The information is intended to help you evaluate this product. FASL LLC reserves the right to change or discontinue work on this proposed product without notice. A D V A N C E I N F O R M A T I O N General Description The S29JL032H is a 32 megabit, 3.0 volt-only flash memory device, organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. Word mode data appears on DQ15-DQ0; byte mode data appears on DQ7-DQ0. The device is designed to be programmed in-system with the standard 3.0 volt VCC supply, and can also be programmed in standard EPROM programmers. The device is available with an access time of 55, 60, 70, or 90 ns and is offered in a 48-pin TSOP package. Standard control pins--chip enable (CE#), write enable (WE#), and output enable (OE#)--control normal read and write operations, and avoid bus contention issues. The device requires only a single 3.0 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. Simultaneous Read/Write Operations with Zero Latency The Simultaneous Read/Write architecture provides simultaneous operation by dividing the memory space into separate banks (see Table 2). Sector addresses are fixed, system software can be used to form user-defined bank groups. During an Erase/Program operation, any of the non-busy banks may be read from. Note that only two banks can operate simultaneously. The device can improve overall system performance by allowing a host system to program or erase in one bank, then immediately and simultaneously read from the other bank, with zero latency. This releases the system from waiting for the completion of program or erase operations. The S29JL032H can be organized as both a top and bottom boot sector configuration. S29JL032H Features The SecSiTM (Secured Silicon) Sector is an extra 256 byte sector capable of being permanently locked by FASL or customers. The SecSi Customer Indicator Bit (DQ6) is permanently set to 1 if the part has been customer locked, permanently set to 0 if the part has been factory locked, and is 0 if customer lockable. This way, customer lockable parts can never be used to replace a factory locked part. Factory locked parts provide several options. The SecSi Sector may store a secure, random 16 byte ESN (Electronic Serial Number), customer code (programmed through Spansion programming services), or both. Customer Lockable parts may utilize the SecSi Sector as bonus space, reading and writing like any other flash sector, or may permanently lock their own code there. DMS (Data Management Software) allows systems to easily take advantage of the advanced architecture of the simultaneous read/write product line by allowing removal of EEPROM devices. DMS will also allow the system software to be simplified, as it will perform all functions necessary to modify data in file structures, as opposed to single-byte modifications. To write or update a particular piece of data (a phone number or configuration data, for example), the user only needs to state which piece of data is to be updated, and where the updated data is located in the system. This is an advantage compared to systems where userwritten software must keep track of the old data location, status, logical to physical translation of the data onto the Flash memory device (or memory devices), 2 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N and more. Using DMS, user-written software does not need to interface with the Flash memory directly. Instead, the user's software accesses the Flash memory by calling one of only six functions. The device offers complete compatibility with the JEDEC 42.4 single-power-supply Flash command set standard. Commands are written to the command register using standard microprocessor write timings. Reading data out of the device is similar to reading from other Flash or EPROM devices. The host system can detect whether a program or erase operation is complete by using the device status bits: RY/BY# pin, DQ7 (Data# Polling) and DQ6/DQ2 (toggle bits). After a program or erase cycle has been completed, the device automatically returns to the read mode. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of the sectors of memory. This can be achieved in-system or via programming equipment. The device offers two power-saving features. When addresses have been stable for a specified amount of time, the device enters the automatic sleep mode. The system can also place the device into the standby mode. Power consumption is greatly reduced in both modes.

May 21, 2004 S29JL032HA0 S29JL032H 9 A D V A N C E I N F O R M A T I O N Device Bus Operations This section describes the requirements and use of the device bus operations, which are initiated through the internal command register. The command register itself does not occupy any addressable memory location. The register is a latch used to store the commands, along with the address and data information needed to execute the command. The contents of the register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. Table 1 lists the device bus operations, the inputs and control levels they require, and the resulting output. The following subsections describe each of these operations in further detail. Table 1. S29JL032H Device Bus Operations DQ15-DQ8 Operation CE# OE# WE# RESET# WP#/ACC Addresses (Note 2) BYTE# = VIH BYTE# = VIL DQ7-DQ0 DQ14-DQ8 = HighZ, DQ15 = A-1 DOUT Read L L H H L/H AIN DOUT Write L H L H (Note 3) AIN DIN VCC 0.3 V X X VCC 0.3 V L/H X High-Z High-Z High-Z Output Disable L H H H L/H X High-Z High-Z High-Z Reset X X X L L/H X High-Z High-Z High-Z Sector Protect (Note 2) L H L VID L/H SA, A6 = L, A1 = H, A0 = L X X DIN Sector Unprotect (Note 2) L H L VID (Note 3) SA, A6 = H, A1 = H, A0 = L X X DIN Temporary Sector Unprotect X X X VID (Note 3) AIN DIN High-Z DIN Standby DIN Legend: L = Logic Low = VIL, H = Logic High = VIH, VID = 11.5-12.5 V, VHH = 9.0 0.5 V, X = Don't Care, SA = Sector Address, AIN = Address In, DIN = Data In, DOUT = Data Out Notes: 1. Addresses are A20:A0 in word mode (BYTE# = VIH), A20:A-1 in byte mode (BYTE# = VIL). 2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the "Sector/Sector Block Protection and Unprotection" section. 3. If WP#/ACC = VIL, the two outermost boot sectors remain protected. If WP#/ACC = VIH, protection on the two outermost boot sectors depends on whether they were last protected or unprotected using the method described in "Sector/Sector Block Protection and Unprotection". If WP#/ACC = VHH, all sectors will be unprotected. 10 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N Word/Byte Configuration The BYTE# pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE# pin is set at logic `1', the device is in word configuration, DQ15-DQ0 are active and controlled by CE# and OE#. If the BYTE# pin is set at logic `0', the device is in byte configuration, and only data I/O pins DQ7-DQ0 are active and controlled by CE# and OE#. The data I/ O pins DQ14-DQ8 are tri-stated, and the DQ15 pin is used as an input for the LSB (A-1) address function. Requirements for Reading Array Data To read array data from the outputs, the system must drive the CE# and OE# pins to VIL. CE# is the power control and selects the device. OE# is the output control and gates array data to the output pins. WE# should remain at VIH. The BYTE# pin determines whether the device outputs array data in words or bytes. The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses on the device address inputs produce valid data on the device data outputs. Each bank remains enabled for read access until the command register contents are altered. Refer to the AC Read-Only Operations table for timing specifications and to 14 for the timing diagram. ICC1 in the DC Characteristics table represents the active current specification for reading array data. Writing Commands/Command Sequences To write a command or command sequence (which includes programming data to the device and erasing sectors of memory), the system must drive WE# and CE# to VIL, and OE# to VIH. For program operations, the BYTE# pin determines whether the device accepts program data in bytes or words. Refer to "Word/Byte Configuration" for more information. The device features an Unlock Bypass mode to facilitate faster programming. Once a bank enters the Unlock Bypass mode, only two write cycles are required to program a word or byte, instead of four. The "Byte/Word Program Command Sequence" section has details on programming data to the device using both standard and Unlock Bypass command sequences. An erase operation can erase one sector, multiple sectors, or the entire device. Tables 3 and 4 indicate the address space that each sector occupies. Similarly, a "sector address" is the address bits required to uniquely select a sector. The "Command Definitions" section has details on erasing a sector or the entire chip, or suspending/resuming the erase operation. The device address space is divided into four banks. A "bank address" is the address bits required to uniquely select a bank. ICC2 in the DC Characteristics table represents the active current specification for the write mode. The AC Characteristics section contains timing specification tables and timing diagrams for write operations. May 21, 2004 S29JL032HA0 S29JL032H 11 A D V A N C E I N F O R M A T I O N Accelerated Program Operation The device offers accelerated program operations through the ACC function. This is one of two functions provided by the WP#/ACC pin. This function is primarily intended to allow faster manufacturing throughput at the factory. If the system asserts VHH on this pin, the device automatically enters the aforementioned Unlock Bypass mode, temporarily unprotects any protected sectors, and uses the higher voltage on the pin to reduce the time required for program operations. The system would use a two-cycle program command sequence as required by the Unlock Bypass mode. Removing VHH from the WP#/ACC pin returns the device to normal operation. Note that VHH must not be asserted on WP#/ACC for operations other than accelerated programming, or device damage may result. In addition, the WP#/ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. See "Write Protect (WP#)" on page 22. for related information. Autoselect Functions If the system writes the autoselect command sequence, the device enters the autoselect mode. The system can then read autoselect codes from the internal register (which is separate from the memory array) on DQ15-DQ0. Standard read cycle timings apply in this mode. Refer to the Autoselect Mode and Autoselect Command Sequence sections for more information. Simultaneous Read/Write Operations with Zero Latency This device is capable of reading data from one bank of memory while programming or erasing in the other bank of memory. An erase operation may also be suspended to read from or program to another location within the same bank (except the sector being erased). Figure 21 shows how read and write cycles may be initiated for simultaneous operation with zero latency. ICC6 and ICC7 in the DC Characteristics table represent the current specifications for read-while-program and read-while-erase, respectively. 12 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N Standby Mode When the system is not reading or writing to the device, it can place the device in the standby mode. In this mode, current consumption is greatly reduced, and the outputs are placed in the high impedance state, independent of the OE# input. The device enters the CMOS standby mode when the CE# and RESET# pins are both held at VCC 0.3 V. (Note that this is a more restricted voltage range than VIH.) If CE# and RESET# are held at VIH, but not within VCC 0.3 V, the device will be in the standby mode, but the standby current will be greater. The device requires standard access time (tCE) for read access when the device is in either of these standby modes, before it is ready to read data. If the device is deselected during erasure or programming, the device draws active current until the operation is completed. ICC3 in the DC Characteristics table represents the standby current specification. Automatic Sleep Mode The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables this mode when addresses remain stable for tACC + 30 ns. The automatic sleep mode is independent of the CE#, WE#, and OE# control signals. Standard address access timings provide new data when addresses are changed. While in sleep mode, output data is latched and always available to the system. ICC5 in the DC Characteristics table represents the automatic sleep mode current specification. RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity. Current is reduced for the duration of the RESET# pulse. When RESET# is held at VSS0.3 V, the device draws CMOS standby current (ICC4). If RESET# is held at VIL but not within VSS0.3 V, the standby current will be greater. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory. If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a "0" (busy) until the internal reset operation is complete, which requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/ BY# to determine whether the reset operation is complete. If RESET# is asserted when a program or erase operation is not executing (RY/BY# pin is "1"), the reset operation is completed within a time of tREADY (not during Embedded Algorithms). The system can read data tRH after the RESET# pin returns to VIH. Refer to the AC Characteristics tables for RESET# parameters and to 15 for the timing diagram.

This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm. However, the autoselect codes can also be accessed in-system through the command register. When using programming equipment, the autoselect mode requires VID on address pin A9. Address pins must be as shown in Table 5. In addition, when verifying sector protection, the sector address must appear on the appropriate highest order address bits. Table 5 shows the remaining address bits that are don't care. When all necessary bits have been set as required, the programming equipment may then read the corresponding identifier code on DQ7-DQ0. However, the autoselect codes can also be accessed in-system through the command register, for instances when the S29JL032H is erased or programmed in a system without access to high voltage on the A9 pin. The command sequence is illustrated in Table 13. Note that if a Bank Address (BA) on address bits A20, A19 and A18 is asserted during the third write cycle of the autoselect command, the host system can read autoselect data from that bank and then immediately read array data from another bank, without exiting the autoselect mode. To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown in Table 13. This method does not require VID.

A sector block consists of two or more adjacent sectors that are protected or unprotected at the same time (see Table 6). The hardware sector protection feature disables both program and erase operations in any sector. The hardware sector unprotection feature re-enables both program and erase operations in previously protected sectors. Sector protection/ unprotection can be implemented via two methods. Table 6.

Figure 2 shows the algorithms and Figure 26 shows the timing diagram. For sector unprotect, all unprotected sectors must first be protected prior to the first sector unprotect write cycle. Note that the sector unprotect algorithm unprotects all sectors in parallel. All previously protected sectors must be individually re-protected. To change data in protected sectors efficiently, the temporary sector unprotect function is available. See "Temporary Sector Unprotect" . The device is shipped with all sectors unprotected. Optional Spansion programming service enable programming and protecting sectors at the factory prior to shipping the device. Contact your local sales office for details. It is possible to determine whether a sector is protected or unprotected. See the Autoselect Mode section for details. May 21, 2004 S29JL032HA0 S29JL032H 21 A D V A N C E I N F O R M A T I O N Write Protect (WP#) The Write Protect function provides a hardware method of protecting certain boot sectors without using VID. This function is one of two provided by the WP#/ACC pin. If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the two outermost 8 Kbyte boot sectors independently of whether those sectors were protected or unprotected using the method described in "Sector/Sector Block Protection and Unprotection". The two outermost 8 Kbyte boot sectors are the two sectors containing the lowest addresses in a bottomboot-configured device, or the two sectors containing the highest addresses in a top-boot-configured device. If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the two outermost 8K Byte boot sectors were last set to be protected or unprotected. That is, sector protection or unprotection for these two sectors depends on whether they were last protected or unprotected using the method described in "Sector/Sector Block Protection and Unprotection". Note that the WP#/ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. Table 8. WP#/ACC Modes Device Mode WP# Input Voltage VIL Disables programming and erasing in the two outermost boot sectors VIH Enables programming and erasing in the two outermost boot sectors, dependent on whether they were last protected or unprotected. VHH Enables accelerated programming (ACC). See "Accelerated Program Operation" on page 12.. Temporary Sector Unprotect (Note: For the following discussion, the term "sector" applies to both sectors and sector blocks. A sector block consists of two or more adjacent sectors that are protected or unprotected at the same time (see Table 6 and Table 7). This feature allows temporary unprotection of previously protected sectors to change data in-system. The Temporary Sector Unprotect mode is activated by setting the RESET# pin to VID. During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses. Once VID is removed from the RESET# pin, all the previously protected sectors are protected again. shows the algorithm, and 25 shows the timing diagrams, for this feature. If the WP#/ACC pin is at VIL, the two outermost boot sectors will remain protected during the Temporary sector Unprotect mode. 22 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N .

The SecSi Sector is 256 bytes in length, and uses a SecSi Sector Indicator Bit (DQ7) to indicate whether or not the SecSi Sector is locked when shipped from the factory. This bit is permanently set at the factory and cannot be changed, which prevents cloning of a factory locked part. This ensures the security of the ESN once the product is shipped to the field. The product is available with the SecSi Sector either factory locked or customer lockable. The factory-locked version is always protected when shipped from the factory, and has the SecSi (Secured Silicon) Sector Indicator Bit permanently set to a "1." The customer-lockable version is shipped with the SecSi Sector unprotected, allowing customers to utilize the that sector in any manner they choose. The customer-lockable version has the SecSi (Secured Silicon) Sector Indicator Bit permanently set to a "0." Thus, the SecSi Sector Indicator Bit prevents customer-lockable devices from being used to replace devices that are factory locked. The SecSi Customer Indicator Bit (DQ6) is permanently set to 1 if the part has been customer locked, permanently set to 0 if the part has been factory locked, and is 0 if customer lockable. The system accesses the SecSi Sector Secure through a command sequence (see "Enter SecSiTM Sector/Exit SecSi Sector Command Sequence"). After the system has written the Enter SecSi Sector command sequence, it may read the SecSi Sector by using the addresses normally occupied by the boot sectors. This mode of operation continues until the system issues the Exit SecSi Sector command sequence, or until power is removed from the device. On power-up, or following a hardware reset, the device reverts to sending commands to the first 256 bytes of Sector 0. Note that the ACC function and unlock bypass modes are not available when the SecSi Sector is enabled. Factory Locked: SecSi Sector Programmed and Protected At the Factory In a factory locked device, the SecSi Sector is protected when the device is shipped from the factory. The SecSi Sector cannot be modified in any way. The device is preprogrammed with both a random number and a secure ESN. The 8word random number is at addresses 000000h-000007h in word mode (or 000000h-00000Fh in byte mode). The secure ESN is programmed in the next 8 words at addresses 000008h-00000Fh (or 000010h-00001Fh in byte mode). The device is available preprogrammed with one of the following: A random, secure ESN only Customer code through Spansion programming services Both a random, secure ESN and customer code through Spansion programming services Contact an your local sales office for details on using Spansion programming services. Customer Lockable: SecSi Sector NOT Programmed or Protected At the Factory If the security feature is not required, the SecSi Sector can be treated as an additional Flash memory space. The SecSi Sector can be read any number of times, but can be programmed and locked only once. Note that the accelerated programming (ACC) and unlock bypass functions are not available when programming the SecSi Sector. May 21, 2004 S29JL032HA0 S29JL032H 25 A D V A N C E I N F O R M A T I O N The SecSi Sector area can be protected using one of the following procedures: Write the three-cycle Enter SecSi Sector Region command sequence, and then follow the in-system sector protect algorithm as shown in Figure 2, except that RESET# may be at either VIH or VID. This allows in-system protection of the SecSi Sector Region without raising any device pin to a high voltage. Note that this method is only applicable to the SecSi Sector. To verify the protect/unprotect status of the SecSi Sector, follow the algorithm shown in Figure 3. Once the SecSi Sector is locked and verified, the system must write the Exit SecSi Sector Region command sequence to return to reading and writing the remainder of the array. The SecSi Sector lock must be used with caution since, once locked, there is no procedure available for unlocking the SecSi Sector area and none of the bits in the SecSi Sector memory space can be modified in any way. START If data = 00h, SecSi Sector is unprotected. If data = 01h, SecSi Sector is protected. RESET# = VIH or VID Wait 1 ms Write 60h to any address Remove VIH or VID from RESET# Write 40h to SecSi Sector address with A6 = 0, A1 = 1, A0 = 0 Read from SecSi Sector address with A6 = 0, A1 = 1, A0 = 0 Figure 3. Write reset command SecSi Sector Protect Verify complete SecSi Sector Protect Verify Hardware Data Protection The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadvertent writes (refer to Table 13 for command definitions). In addition, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during VCC power-up and power-down transitions, or from system noise. Low VCC Write Inhibit When VCC is less than VLKO, the device does not accept any write cycles. This protects data during VCC power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets to the read 26 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N mode. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control pins to prevent unintentional writes when VCC is greater than VLKO. Write Pulse "Glitch" Protection Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle. Logical Inhibit Write cycles are inhibited by holding any one of OE# = VIL, CE# = VIH or WE# = VIH. To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a logical one. Power-Up Write Inhibit If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept commands on the rising edge of WE#. The internal state machine is automatically reset to the read mode on power-up. Common Flash Memory Interface (CFI) The Common Flash Interface (CFI) specification outlines device and host system software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h in word mode (or address AAh in byte mode), any time the device is ready to read array data. The system can read CFI information at the addresses given in Tables 9-12. To terminate reading CFI data, the system must write the reset command.The CFI Query mode is not accessible when the device is executing an Embedded Program or embedded Erase algorithm. The system can also write the CFI query command when the device is in the autoselect mode. The device enters the CFI query mode, and the system can read CFI data at the addresses given in Tables 9-12. The system must write the reset command to reading array data. For further information, please refer to the CFI Specification and CFI Publication 100. Contact your local sales office for copies of these documents.

Table 13 defines the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence may place the device in an unknown state. A reset command is then required to return the device to reading array data. All addresses are latched on the falling edge of WE# or CE#, whichever happens later. All data is latched on the rising edge of WE# or CE#, whichever happens first. Refer to the AC Characteristics section for timing diagrams. Reading Array Data The device is automatically set to reading array data after device power-up. No commands are required to retrieve data. Each bank is ready to read array data after completing an Embedded Program or Embedded Erase algorithm. After the device accepts an Erase Suspend command, the corresponding bank enters the erase-suspend-read mode, after which the system can read data from any non-erase-suspended sector within the same bank. The system can read array data using the standard read timing, except that if it reads at an address within erase-suspended sectors, the device outputs status data. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See the Erase Suspend/Erase Resume Commands section for more information. The system must issue the reset command to return a bank to the read (or erasesuspend-read) mode if DQ5 goes high during an active program or erase operation, or if the bank is in the autoselect mode. See the next section, Reset Command, for more information. See also Requirements for Reading Array Data in the Device Bus Operations section for more information. The Read-Only Operations table provides the read parameters, and 14 shows the timing diagram. Reset Command Writing the reset command resets the banks to the read or erase-suspend-read mode. Address bits are don't cares for this command. The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the bank to which the system was writing to the read mode. Once erasure begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the bank to which the system was writing to the read mode. If the program command sequence is written to a bank that is in the Erase Suspend mode, writing the reset command returns that bank to the erase-suspend-read mode. Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in an autoselect command sequence. Once in the autoselect mode, the reset command must be written to return to the read mode. If a bank entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns that bank to the erase-suspend-read mode. May 21, 2004 S29JL032HA0 S29JL032H 31 A D V A N C E I N F O R M A T I O N If DQ5 goes high during a program or erase operation, writing the reset command returns the banks to the read mode (or erase-suspend-read mode if that bank was in Erase Suspend). Autoselect Command Sequence The autoselect command sequence allows the host system to access the manufacturer and device codes, and determine whether or not a sector is protected. The autoselect command sequence may be written to an address within a bank that is either in the read or erase-suspend-read mode. The autoselect command may not be written while the device is actively programming or erasing in another bank. The autoselect command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle that contains the bank address and the autoselect command. The bank then enters the autoselect mode. The system may read any number of autoselect codes without reinitiating the command sequence. Table 13 shows the address and data requirements. To determine sector protection information, the system must write to the appropriate bank address (BA) and sector address (SA). Tables 3 and 4 show the address range and bank number associated with each sector. The system must write the reset command to return to the read mode (or erasesuspend-read mode if the bank was previously in Erase Suspend). Enter SecSiTM Sector/Exit SecSi Sector Command Sequence The SecSi Sector region provides a secured data area containing a random, sixteen-byte electronic serial number (ESN). The system can access the SecSi Sector region by issuing the three-cycle Enter SecSi Sector command sequence. The device continues to access the SecSi Sector region until the system issues the four-cycle Exit SecSi Sector command sequence. The Exit SecSi Sector command sequence returns the device to normal operation. The SecSi Sector is not accessible when the device is executing an Embedded Program or embedded Erase algorithm. Table 13 shows the address and data requirements for both command sequences. See also "SecSiTM (Secured Silicon) Sector Flash Memory Region" for further information. Note that the ACC function and unlock bypass modes are not available when the SecSi Sector is enabled. Byte/Word Program Command Sequence The system may program the device by word or byte, depending on the state of the BYTE# pin. Programming is a four-bus-cycle operation. The program command sequence is initiated by writing two unlock write cycles, followed by the program set-up command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further controls or timings. The device automatically provides internally generated program pulses and verifies the programmed cell margin. Table 13 shows the address and data requirements for the byte program command sequence. When the Embedded Program algorithm is complete, that bank then returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by using DQ7, DQ6, or RY/BY#. Refer to the Write Operation Status section for information on these status bits. 32 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hardware reset immediately terminates the program operation. The program command sequence should be reinitiated once that bank has returned to the read mode, to ensure data integrity. Note that the SecSi Sector, autoselect, and CFI functions are unavailable when a program operation is in progress. Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from "0" back to a "1." Attempting to do so may cause that bank to set DQ5 = 1, or cause the DQ7 and DQ6 status bits to indicate the operation was successful. However, a succeeding read will show that the data is still "0." Only erase operations can convert a "0" to a "1." Unlock Bypass Command Sequence The unlock bypass feature allows the system to program bytes or words to a bank faster than using the standard program command sequence. The unlock bypass command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. That bank then enters the unlock bypass mode. A two-cycle unlock bypass program command sequence is all that is required to program in this mode. The first cycle in this sequence contains the unlock bypass program command, A0h; the second cycle contains the program address and data. Additional data is programmed in the same manner. This mode dispenses with the initial two unlock cycles required in the standard program command sequence, resulting in faster total programming time. Table 13 shows the requirements for the command sequence. During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command sequence. (See Table 12). The device offers accelerated program operations through the WP#/ACC pin. When the system asserts VHH on the WP#/ACC pin, the device automatically enters the Unlock Bypass mode. The system may then write the two-cycle Unlock Bypass program command sequence. The device uses the higher voltage on the WP#/ACC pin to accelerate the operation. Note that the WP#/ACC pin must not be at VHH for any operation other than accelerated programming, or device damage may result. In addition, the WP#/ACC pin must not be left floating or unconnected; inconsistent behavior of the device may result. 4 illustrates the algorithm for the program operation. Refer to the Erase and Program Operations table in the AC Characteristics section for parameters, and Figure 18 for timing diagrams.

Program Operation Chip Erase Command Sequence Chip erase is a six bus cycle operation. The chip erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. Table 13 shows the address and data requirements for the chip erase command sequence. When the Embedded Erase algorithm is complete, that bank returns to the read mode and addresses are no longer latched. The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. Refer to the Write Operation Status section for information on these status bits. Any commands written during the chip erase operation are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the chip erase command sequence should be reinitiated once that bank has returned to reading array data, to ensure data integrity. Note that the SecSi Sector, autoselect, and CFI functions are unavailable when an erase operation is in progress. 34 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N 5 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters, and Figure 20 section for timing diagrams. Sector Erase Command Sequence Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock cycles are written, and are then followed by the address of the sector to be erased, and the sector erase command. Table 13 shows the address and data requirements for the sector erase command sequence. The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire sector for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. After the command sequence is written, a sector erase time-out of 80 s occurs. During the time-out period, additional sector addresses and sector erase commands may be written. Loading the sector erase buffer may be done in any sequence, and the number of sectors may be from one sector to all sectors. The time between these additional cycles must be less than 80 s, otherwise erasure may begin. Any sector erase address and command following the exceeded timeout may or may not be accepted. It is recommended that processor interrupts be disabled during this time to ensure all commands are accepted. The interrupts can be re-enabled after the last Sector Erase command is written. Any command other than Sector Erase or Erase Suspend during the time-out period resets that bank to the read mode. The system must rewrite the command sequence and any additional addresses and commands. The system can monitor DQ3 to determine if the sector erase timer has timed out (See the section on DQ3: Sector Erase Timer.). The time-out begins from the rising edge of the final WE# or CE# pulse (first rising edge) in the command sequence. When the Embedded Erase algorithm is complete, the bank returns to reading array data and addresses are no longer latched. Note that while the Embedded Erase operation is in progress, the system can read data from the non-erasing bank. The system can determine the status of the erase operation by reading DQ7, DQ6, DQ2, or RY/BY# in the erasing bank. Refer to the Write Operation Status section for information on these status bits. Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the sector erase command sequence should be reinitiated once that bank has returned to reading array data, to ensure data integrity. Note that the SecSi Sector, autoselect, and CFI functions are unavailable when an erase operation is in progress. 5 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters, and Figure 20 section for timing diagrams.

Erase Operation Erase Suspend/Erase Resume Commands The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. The bank address is required when writing this command. This command is valid only during the sector erase operation, including the 80 s time-out period during the sector erase command sequence. The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. The bank address must contain one of the sectors currently selected for erase. When the Erase Suspend command is written during the sector erase operation, the device requires a maximum of 20 s to suspend the erase operation. However, when the Erase Suspend command is written during the sector erase time-out, the device immediately terminates the time-out period and suspends the erase operation. After the erase operation has been suspended, the bank enters the erase-suspend-read mode. The system can read data from or program data to any sector not selected for erasure. (The device "erase suspends" all sectors selected for erasure.) Reading at any address within erase-suspended sectors produces status information on DQ7-DQ0. The system can use DQ7, or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. Refer to the Write Operation Status section for information on these status bits. 36 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N After an erase-suspended program operation is complete, the bank returns to the erase-suspend-read mode. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard Byte Program operation. Refer to the Write Operation Status section for more information. In the erase-suspend-read mode, the system can also issue the autoselect command sequence. The device allows reading autoselect codes even at addresses within erasing sectors, since the codes are not stored in the memory array. When the device exits the autoselect mode, the device reverts to the Erase Suspend mode, and is ready for another valid operation. Refer to the Autoselect Mode and Autoselect Command Sequence sections for details. To resume the sector erase operation, the system must write the Erase Resume command. The bank address of the erase-suspended bank is required when writing this command. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the chip has resumed erasing. May 21, 2004 S29JL032HA0 S29JL032H 37 A D V A N C E Cycles Table 13.

The data is 82h for factory locked, 40h for customer locked, and 02h for not factory/customer locked. The data is 00h for an unprotected sector/sector block and 01h for a protected sector/sector block. The Unlock Bypass command is required prior to the Unlock Bypass Program command. The Unlock Bypass Reset command is required to return to the read mode when the bank is in the unlock bypass mode. The system may read and program in non-erasing sectors, or enter the autoselect mode, when in the Erase Suspend mode. The Erase Suspend command is valid only during a sector erase operation, and requires the bank address. The Erase Resume command is valid only during the Erase Suspend mode, and requires the bank address. Command is valid when device is ready to read array data or when device is in autoselect mode. S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N Write Operation Status The device provides several bits to determine the status of a program or erase operation: DQ2, DQ3, DQ5, DQ6, and DQ7. Table 14 and the following subsections describe the function of these bits. DQ7 and DQ6 each offer a method for determining whether a program or erase operation is complete or in progress. The device also provides a hardware-based output signal, RY/BY#, to determine whether an Embedded Program or Erase operation is in progress or has been completed. DQ7: Data# Polling The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase algorithm is in progress or completed, or whether a bank is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the command sequence. During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a protected sector, Data# Polling on DQ7 is active for approximately 1 s, then that bank returns to the read mode. During the Embedded Erase algorithm, Data# Polling produces a "0" on DQ7. When the Embedded Erase algorithm is complete, or if the bank enters the Erase Suspend mode, Data# Polling produces a "1" on DQ7. The system must provide an address within any of the sectors selected for erasure to read valid status information on DQ7. After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on DQ7 is active for approximately 100 s, then the bank returns to the read mode. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. However, if the system reads DQ7 at an address within a protected sector, the status may not be valid. When the system detects DQ7 has changed from the complement to true data, it can read valid data at DQ15-DQ0 (or DQ7-DQ0 for x8-only device) on the following read cycles. Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ15-DQ8 (DQ7-DQ0 for x8only device) while Output Enable (OE#) is asserted low. That is, the device may change from providing status information to valid data on DQ7. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device has completed the program or erase operation and DQ7 has valid data, the data outputs on DQ15-DQ0 may be still invalid. Valid data on DQ15-DQ0 (or DQ7-DQ0 for x8-only device) will appear on successive read cycles. Table 14 shows the outputs for Data# Polling on DQ7. 6 shows the Data# Polling algorithm. 22 in the AC Characteristics section shows the Data# Polling timing diagram.

VA = Valid address for programming. During a sector erase operation, a valid address is any sector address within the sector being erased. During chip erase, a valid address is any non-protected sector address. 2. DQ7 should be rechecked even if DQ5 = "1" because DQ7 may change simultaneously with DQ5. Figure 6. 40 Data# Polling Algorithm S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N RY/BY#: Ready/Busy# The RY/BY# is a dedicated, open-drain output pin which indicates whether an Embedded Algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC. If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.) If the output is high (Ready), the device is in the read mode, the standby mode, or one of the banks is in the erase-suspend-read mode. Table 14 shows the outputs for RY/BY#. DQ6: Toggle Bit I Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete, or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WE# pulse in the command sequence (prior to the program or erase operation), and during the sector erase time-out. During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. The system may use either OE# or CE# to control the read cycles. When the operation is complete, DQ6 stops toggling. After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for approximately 100 s, then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erase-suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7 (see the subsection on DQ7: Data# Polling). If a program address falls within a protected sector, DQ6 toggles for approximately 1 s after the program command sequence is written, then returns to reading array data. DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete.

See the subsections on DQ6 and DQ2 for more information. Figure 7. Toggle Bit Algorithm DQ2: Toggle Bit II The "Toggle Bit II" on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is, the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. Toggle Bit II is valid after the rising edge of the final WE# pulse in the command sequence. 42 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N DQ2 toggles when the system reads at addresses within those sectors that have been selected for erasure. (The system may use either OE# or CE# to control the read cycles.) But DQ2 cannot distinguish whether the sector is actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sector and mode information. Refer to Table 14 to compare outputs for DQ2 and DQ6. 7 shows the toggle bit algorithm in flowchart form, and the section "DQ2: Toggle Bit II" explains the algorithm. See also the DQ6: Toggle Bit I subsection. 23 shows the toggle bit timing diagram. 24 shows the differences between DQ2 and DQ6 in graphical form. Reading Toggle Bits DQ6/DQ2 Refer to 7 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read DQ15-DQ0 (or DQ7-DQ0 for x8-only device) at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the first. If the toggle bit is not toggling, the device has completed the program or erase operation. The system can read array data on DQ15-DQ0 (or DQ7-DQ0 for x8-only device) on the following read cycle. However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high (see the section on DQ5). If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or erase operation. If it is still toggling, the device did not completed the operation successfully, and the system must write the reset command to return to reading array data. The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not gone high. The system may continue to monitor the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively, it may choose to perform other system tasks. In this case, the system must start at the beginning of the algorithm when it returns to determine the status of the operation (top of 7). DQ5: Exceeded Timing Limits DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a "1," indicating that the program or erase cycle was not successfully completed. The device may output a "1" on DQ5 if the system tries to program a "1" to a location that was previously programmed to "0." Only an erase operation can change a "0" back to a "1." Under this condition, the device halts the operation, and when the timing limit has been exceeded, DQ5 produces a "1." Under both these conditions, the system must write the reset command to return to the read mode (or to the erase-suspend-read mode if a bank was previously in the erase-suspend-program mode). DQ3: Sector Erase Timer After writing a sector erase command sequence, the system may read DQ3 to determine whether or not erasure has begun. (The sector erase timer does not May 21, 2004 S29JL032HA0 S29JL032H 43 A D V A N C E I N F O R M A T I O N apply to the chip erase command.) If additional sectors are selected for erasure, the entire time-out also applies after each additional sector erase command. When the time-out period is complete, DQ3 switches from a "0" to a "1." If the time between additional sector erase commands from the system can be assumed to be less than 50 s, the system need not monitor DQ3. See also the Sector Erase Command Sequence section. After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure that the device has accepted the command sequence, and then read DQ3. If DQ3 is "1," the Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored until the erase operation is complete. If DQ3 is "0," the device will accept additional sector erase commands. To ensure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last command might not have been accepted. Table 14 shows the status of DQ3 relative to the other status bits. Table 14.

DQ5 switches to `1' when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits. Refer to the section on DQ5 for more information. 2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details. 3. When reading write operation status bits, the system must always provide the bank address where the Embedded Algorithm is in progress. The device outputs array data if the system addresses a non-busy bank. 44 S29JL032H S29JL032HA0 May 21, 2004 A D V A N C E I N F O R M A T I O N Absolute Maximum Ratings Storage Temperature Plastic Packages . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .-65C to +150C Ambient Temperature with Power Applied . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .-65C to +125C Voltage with Respect to Ground VCC (Note 1). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.5 V to +4.0 V A9, OE#, and RESET# (Note 2). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.5 V to +12.5 V WP#/ACC. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.5 V to +10.5 V All other pins (Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.5 V to VCC +0.5 V Output Short Circuit Current (Note 3) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 200 mA Notes: 1.

See Figure 8. Maximum DC input voltage on pin A9 is +12.5 V which may overshoot to +14.0 V for periods up to 20 ns. Maximum DC input voltage on WP#/ACC is +9.5 V which may overshoot to +12.0 V for periods up to 20 ns. 3. No more than one output may be shorted to ground at a time. Duration of the short circuit should not be greater than one second. Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections of this data sheet is not implied.

Typical program and erase times assume the following conditions: 25C, VCC = 3.0 V, 100,000 cycles; checkerboard data pattern. 2. Under worst case conditions of 90C, VCC = 2.7 V, 1,000,000 cycles. 3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes program faster than the maximum program times listed. 4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure. 5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See Table 13 for further information on command definitions. 6. The device has a minimum cycling endurance of 100,000 cycles per sector.
