TM memory FUJITSU SEMICONDUCTOR DATA SHEET DS05-20911-1E FLASH MEMORY CMOS 8 M (1 M x 8/512 K x 16) BIT MBM29SL800TE/BE-90/10 DESCRIPTION The MBM29SL800TE/BE are a 8 M-bit, 1.8 V-only Flash memory organized as 1 Mbytes of 8 bits each or 512 Kwords of 16 bits each. The MBM29SL800TE/BE are offered in a 48-ball FBGA and 45-ball SCSP packages. These devices are designed to be programmed in-system with the standard system 1.8 V VCC supply. 12.0 V VPP and 5.0 V VCC are not required for write or erase operations. The devices can also be reprogrammed in standard EPROM programmers.

To eliminate bus contention the devices have separate chip enable (CE) , write enable (WE) , and output enable (OE) controls. The device supports pin and command set compatible with JEDEC standard E2PROMs. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the devices is similar to reading from 5.0 V and 12.0 V Flash or EPROM devices. The device is programmed by executing the program command sequence. This will invoke the Embedded Program Algorithm which is an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. Typically, each sector can be programmed and verified in about 0.5 seconds. Erase is accomplished by executing the erase command sequence. This will invoke the Embedded Erase Algorithm which is an internal algorithm that automatically preprograms the array if it is not already programmed before executing the erase operation. During erase, the devices automatically time the erase pulse widths and verify proper cell margin. Each sector is typically erased and verified in 1.5 second. (If already completely preprogrammed.) The devices also feature a sector erase architecture. The sector mode allows each sector to be erased and reprogrammed without affecting other sectors. The MBM29SL800TE/BE are erased when shipped from the factory. The devices feature single 1.8 V power supply operation for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. A low VCC detector automatically inhibits write operations on the loss of power. The end of program or erase is detected by Data Polling of DQ7, by the Toggle Bit feature on DQ6, or the RY/BY output pin. Once the end of a program or erase cycle has been completed, the device internally returns to the read mode. Fujitsu's Flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality, reliability, and cost effectiveness. The MBM29SL800TE/BE memories electrically erase the entire chip or all bits within a sector simultaneously via Fowler-Nordhiem tunneling. The bytes/words are programmed one byte/word at a time using the EPROM programming mechanism of hot electron injection. 2 MBM29SL800TE/BE-90/10 FEATURES * 0.23 m Process Technology * Single 1.8 V read, program, and erase Minimizes system level power requirements * Compatible with JEDEC-standard world-wide pinouts 48-ball FBGA (Package suffix : PBT) 45-ball SCSP (Package suffix : PW) * Minimum 100,000 program/erase cycles * High performance 90 ns maximum access time * Sector erase architecture One 8 Kword, two 4 Kwords, one 16 Kword, and fifteen 32 Kwords sectors in word mode One 16 Kbyte, two 8 Kbytes, one 32 Kbyte, and fifteen 64 Kbytes sectors in byte mode Any combination of sectors can be concurrently erased.

When using both pins, a CMOS standby mode is achieved with CE and RESET inputs both held at VCC 0.3 V. Under this condition the current consumed is less than 5 A. The device can be read with standard access time (tCE) from either of these standby modes. During Embedded Algorithm operation, VCC active current (ICC2) is required even CE = "H". When using the RESET pin only, a CMOS standby mode is achieved with RESET input held at VSS 0.3 V (CE = "H" or "L") . Under this condition the current is consumed is less than 5 A. Once the RESET pin is taken high, the device requires tRH of wake up time before outputs are valid for read access. In the standby mode the outputs are in the high impedance state, independent of the OE input. Automatic Sleep Mode There is a function called automatic sleep mode to restrain power consumption during read-out of MBM29SL800TE/BE data. This mode can be used effectively with an application requested low power consumption such as handy terminals. To activate this mode, MBM29SL800TE/BE automatically switch themselves to low power mode when MBM29SL800TE/BE addresses remain stably during access fine of 150 ns. It is not necessary to control CE, WE, and OE on the mode. Under the mode, the current consumed is typically 1 A (CMOS Level) . Since the data are latched during this mode, the data are read-out continuously. If the addresses are changed, the mode is canceled automatically and MBM29SL800TE/BE read-out the data for changed addresses. Autoselect The autoselect mode allows the reading out of a binary code from the devices and will identify its manufacturer and type. This mode is intended for use by programming equipment for the purpose of automatically matching the devices to be programmed with its corresponding programming algorithm. This mode is functional over the entire temperature range of the devices. To activate this mode, the programming equipment must force VID (10 V to 11 V) on address pin A9. Two identifier bytes may then be sequenced from the devices outputs by toggling address A0 from VIL to VIH. All addresses are DON'T CARES except A0, A1, A6, and A-1. (See "MBM29SL800TE/BE Sector Protection Verify Autoselect Codes" in DEVICE BUS OPERATION.) The manufacturer and device codes may also be read via the command register, for instances when the MBM29SL800TE/BE are erased or programmed in a system without access to high voltage on the A9 pin. The command sequence is illustrated in "MBM29SL800TE/BE Standard Command Definitions" in DEVICE BUS OPERATION. (Refer to Autoselect Command section.) Byte 0 (A0 = VIL) represents the manufacturer's code (Fujitsu = 04h) and (A0 = VIH) represents the device identifier code (MBM29SL800TE = EAh and MBM29SL800BE = 6Bh for x8 mode; MBM29SL800TE = 22EAh and MBM29SL800BE = 226Bh for x16 mode) . These two bytes/words are given in "MBM29LV800TE/BE Sector Protection Verify Autoselect Codes Table" and "Extended Autoselect Code Table" in DEVICE BUS OPERATION. All identifiers for manufactures and device will exhibit odd parity with DQ7 defined as the parity bit. In order to read the proper device codes when executing the autoselect, A1 must be VIL. (See "MBM29SL800TE/BE Sector Protection Verify Autoselect Codes" and "Extended Autoselect Code" in DEVICE BUS OPERATION.) Read Mode The MBM29SL800TE/BE have two control functions which must be satisfied in order to obtain data at the outputs. CE is the power control and should be used for a device selection. OE is the output control and should be used to gate data to the output pins if a device is selected. Address access time (tACC) is equal to the delay from stable addresses to valid output data. The chip enable access time (tCE) is the delay from stable addresses and stable CE to valid data at the output pins. The output enable access time is the delay from the falling edge of OE to valid data at the output pins. (Assuming the addresses have been stable for at least tACC-tOE time.) When reading out a data without changing addresses after power-up, it is necessary to input hardware reset or change CE pin from "H" to "L" 14 MBM29SL800TE/BE-90/10 Output Disable With the OE input at a logic high level (VIH) , output from the devices are disabled. This will cause the output pins to be in a high impedance state. Write Device erasure and programming are accomplished via the command register. The contents of the register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. 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 command register is written by bringing WE to VIL, while CE is at VIL and OE is at VIH. Addresses are latched on the falling edge of WE or CE, whichever happens later; while data is latched on the rising edge of WE or CE, whichever happens first. Standard microprocessor write timings are used. Refer to AC Write Characteristics and the Erase/Programming Waveforms for specific timing parameters. Sector Protection The MBM29SL800TE/BE feature hardware sector protection. This feature will disable both program and erase operations in any number of sectors (0 through 18) . The sector protection feature is enabled using programming equipment at the user's site. The devices are shipped with all sectors unprotected. To activate this mode, the programming equipment must force VID on address pin A9 and control pin OE, CE = VIL, and A6 = VIL. The sector addresses (A18, A17, A16, A15, A14, A13, and A12) should be set to the sector to be protected. "Sector Address Tables (MBM29SL800TE) " and "Sector Address Tables (MBM29SL800TE) " in FLEXIBLE SECTOR-ERASE ARCHITECTURE define the sector address for each of the nineteen (19) individual sectors. Programming of the protection circuitry begins on the falling edge of the WE pulse and is terminated with the rising edge of the same. Sector addresses must be held constant during the WE pulse. See "Sector Protection Timing Diagram" in TIMING DIAGRAM and "Sector Protection Algorithm" in FLOW CHART for sector protection waveforms and algorithm. To verify programming of the protection circuitry, the programming equipment must force VID on address pin A9 with CE and OE at VIL and WE at VIH. Scanning the sector addresses (A18, A17, A16, A15, A14, A13, and A12) while (A6, A1, A0) = (0, 1, 0) will produce a logical "1" code at device output DQ0 for a protected sector. Otherwise the devices will read 00h for unprotected sector. In this mode, the lower order addresses, except for A0, A1, and A6 are DON'T CARES. Address locations with A1 = VIL are reserved for Autoselect manufacturer and device codes. A-1 requires to apply to VIL on byte mode. Temporary Sector Unprotection This feature allows temporary unprotection of previously protected sectors of the MBM29SL800TE/BE devices in order to change data. The Sector Unprotection mode is activated by setting the RESET pin to high voltage (VID) . During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses. Once the VID is taken away from the RESET pin, all the previously protected sectors will be protected again. See "Temporary Sector Unprotection Timing Diagram" in TIMING DIAGRAM and "Temporary Sector Unprotection Algorithm" in FLOW CHART. RESET Hardware Reset The MBM29SL800TE/BE devices may be reset by driving the RESET pin to VIL. The RESET pin has a pulse requirement and has to be kept low (VIL) for at least 500 ns in order to properly reset the internal state machine. Any operation in the process of being executed will be terminated and the internal state machine will be reset to the read mode 20 s after the RESET pin is driven low. Furthermore, once the RESET pin goes high, the devices require an additional tRH before it will allow read access. When the RESET pin is low, the devices will be in the standby mode for the duration of the pulse and all the data output pins will be tri-stated. If a hardware reset occurs during a program or erase operation, the data at that particular location will be corrupted. Please note that the RY/BY output signal should be ignored during the RESET pulse. See "RESET, RY/BY Timing Diagram" in TIMING DIAGRAM for the timing diagram. Refer to Temporary Sector Unprotection for additional functionality. 15 MBM29SL800TE/BE-90/10 COMMAND DEFINITIONS Device operations are selected by writing specific address and data sequences into the command register. "MBM29SL800TE/BE Standard Command Definitions" in DEVICE BUS OPERATION defines the valid register command sequences. Note that the Erase Suspend (B0h) and Erase Resume (30h) commands are valid only while the Sector Erase operation is in progress. Moreover both Reset commands are functionally equivalent, resetting the device to the read mode. Please note that commands are always written at DQ7 to DQ0 and DQ15 to DQ8 bits are ignored. Reset Command In order to return from Autoselect mode or Exceeded Timing Limits (DQ5 = 1) to Read mode, the Reset operation is initiated by writing the Reset command sequence into the command register. The device remains enabled for reads until the command register contents are altered. The device will automatically power-up in the reset state. In this case, a command sequence is not required to read data. Autoselect Command Flash memories are intended for use in applications where the local CPU alters memory contents. As such, manufacture and device codes must be accessible while the devices reside in the target system. PROM programmers typically access the signature codes by raising A9 to a high voltage. However, multiplexing high voltage onto the address lines is not generally desired system design practice. The device contains an Autoselect command operation to supplement traditional PROM programming methodology. The operation is initiated by writing the Autoselect command sequence into the command register. Following the command write, a read cycle from address XX00h retrieves the manufacture code of 04h. A read cycle from address XX01h for x16 (XX02h for x8) returns the device code (MBM29SL800TE = EAh and MBM29SL800BE = 6Bh for x8 mode; MBM29SL800TE = 22EAh and MBM29SL800BE = 226Bh for x16 mode) . (See "MBM29SL800TE/BE Sector Protection Verify Autoselect Codes" and "Extended Autoselect Code" in DEVICE BUS OPERATION.) All manufacturer and device codes will exhibit odd parity with DQ7 defined as the parity bit. Sector state (protection or unprotection) will be informed by address XX02h for x16 (XX04h for x8) . Scanning the sector addresses (A18, A17, A16, A15, A14, A13, and A12) while (A6, A1, A0) = (0, 1, 0) will produce a logical "1" at device output DQ0 for a protected sector. The programming verification should be perform margin mode on the protected sector. (See "MBM29SL800TE/BE User Bus Operations (BYTE = VIH) " and "MBM29SL800TE/BE User Bus Operations (BYTE = VIL) " in DEVICE BUS OPERATION.) To terminate the operation, it is necessary to write the Reset command sequence into the register, and also to write the Autoselect command during the operation, execute it after writing Reset command sequence. Byte/Word Programming The devices are programmed on a byte-by-byte (or word-by-word) basis. Programming is a four bus cycle operation. There are two "unlock" write cycles. These are followed by the program set-up command and data write cycles. Addresses are latched on the falling edge of CE or WE, whichever happens later and the data is latched on the rising edge of CE or WE, whichever happens first. The rising edge of CE or WE (whichever happens first) begins programming. Upon executing the Embedded Program Algorithm command sequence, the system is not required to provide further controls or timings. The device will automatically provide adequate internally generated program pulses and verify the programmed cell margin. The automatic programming operation is completed when the data on DQ7 is equivalent to data written to this bit at which time the devices return to the read mode and addresses are no longer latched. (See "Hardware Sequence Flags".) Therefore, the devices require that a valid address to the devices be supplied by the system at this particular instance of time. Hence, Data Polling must be performed at the memory location which is being programmed. If hardware reset occurs during the programming operation, it is impossible to guarantee the data are being written. 16 MBM29SL800TE/BE-90/10 Programming is allowed in any sequence and across sector boundaries. Beware that a data "0" cannot be programmed back to a "1". Attempting to do so may either hang up the device or result in an apparent success according to the data polling algorithm but a read from read/reset mode will show that the data is still "0". Only erase operations can convert "0"s to "1"s. "Embedded ProgramTM Algorithm" in FLOW CHART illustrates the Embedded ProgramTM Algorithm using typical command strings and bus operations. Chip Erase Chip erase is a six bus cycle operation. There are two "unlock" write cycles. These are followed by writing the "set-up" command. Two more "unlock" write cycles are then followed by the chip erase command. Chip erase does not require the user to program the device prior to erase. Upon executing the Embedded Erase Algorithm command sequence the devices will automatically program and verify the entire memory for an all zero data pattern prior to electrical erase (Preprogram function) . The system is not required to provide any controls or timings during these operations. The automatic erase begins on the rising edge of the last WE pulse in the command sequence and terminates when the data on DQ7 is "1" (See Write Operation Status section.) at which time the device returns to read the mode. Chip Erase Time; Sector Erase Time x All sectors + Chip Program Time (Preprogramming) "Embedded EraseTM Algorithm" in FLOW CHART illustrates the Embedded EraseTM Algorithm using typical command strings and bus operations. Sector Erase Sector erase is a six bus cycle operation. There are two "unlock" write cycles. These are followed by writing the "set-up" command. Two more "unlock" write cycles are then followed by the Sector Erase command. The sector address (any address location within the desired sector) is latched on the falling edge of WE, while the command (Data = 30h) is latched on the rising edge of WE. After time-out of 50 s from the rising edge of the last sector erase command, the sector erase operation will begin. Multiple sectors may be erased concurrently by writing the six bus cycle operations on "MBM29SL800TE/BE Standard Command Definitions" in DEVICE BUS OPERATION. This sequence is followed with writes of the Sector Erase command to addresses in other sectors desired to be concurrently erased. The time between writes must be less than 50 s otherwise that command will not be accepted and erasure will start. It is recommended that processor interrupts be disabled during this time to guarantee this condition. The interrupts can be re-enabled after the last Sector Erase command is written. A time-out of 50 s from the rising edge of the last WE will initiate the execution of the Sector Erase command (s) . If another falling edge of the WE occurs within the 50 s time-out window the timer is reset. (Monitor DQ3 to determine if the sector erase timer window is still open, see section DQ3, Sector Erase Timer.) Resetting the devices once execution has begun will corrupt the data in the sector. In that case, restart the erase on those sectors and allow them to complete. (Refer to the Write Operation Status section for Sector Erase Timer operation.) Loading the sector erase buffer may be done in any sequence and with any number of sectors (0 to 18) . Sector erase does not require the user to program the devices prior to erase. The devices automatically program all memory locations in the sector (s) to be erased prior to electrical erase (Preprogram function) . When erasing a sector or sectors the remaining unselected sectors are not affected. The system is not required to provide any controls or timings during these operations. The automatic sector erase begins after the 50 s time out from the rising edge of the WE pulse for the last sector erase command pulse and terminates when the data on DQ7 is "1" (See Write Operation Status section.) at which time the devices return to the read mode. Data polling must be performed at an address within any of the sectors being erased. Multiple Sector Erase Time; [Sector Erase Time + Sector Program Time (Preprogramming) ] x Number of Sector Erase "Embedded EraseTM Algorithm" in FLOW CHART illustrates the Embedded EraseTM Algorithm using typical command strings and bus operations. 17 MBM29SL800TE/BE-90/10 Erase Suspend/Resume The Erase Suspend command allows the user to interrupt a Sector Erase operation and then perform data reads from or programs to a sector not being erased. This command is applicable ONLY during the Sector Erase operation which includes the time-out period for sector erase. Writting the Erase Suspend command during the Sector Erase time-out results in immediate termination of the time-out period and suspension of the erase operation. Writing the Erase Resume command resumes the erase operation. The addresses are DON'T CARES when writing the Erase Suspend or Erase Resume command. When the Erase Suspend command is written during the Sector Erase operation, the device will take a maximum of 20 s to suspend the erase operation. When the devices have entered the erase-suspended mode, the RY/BY output pin and the DQ7 bit will be at logic "1", and DQ6 will stop toggling. The user must use the address of the erasing sector for reading DQ6 and DQ7 to determine if the erase operation has been suspended. Further writes of the Erase Suspend command are ignored. When the erase operation has been suspended, the devices default to the erase-suspend-read mode. Reading data in this mode is the same as reading from the standard read mode except that the data must be read from sectors that have not been erase-suspended. Successively reading from the erase-suspended sector while the device is in the erase-suspend-read mode will cause DQ2 to toggle. (See the section on DQ2.) After entering the erase-suspend-read mode, the user can program the device by writing the appropriate command sequence for Program. This program mode is known as the erase-suspend-program mode. Again, programming in this mode is the same as programming in the regular Program mode except that the data must be programmed to sectors that are not erase-suspended. Successively reading from the erase-suspended sector while the devices are in the erase-suspend-program mode will cause DQ2 to toggle. The end of the erasesuspended Program operation is detected by the RY/BY output pin, Data polling of DQ7, or by the Toggle Bit I (DQ6) which is the same as the regular Program operation. Note that DQ7 must be read from the Program address while DQ6 can be read from any address. To resume the operation of Sector Erase, the Resume command (30h) should be written. Any further writes of the Resume command at this point will be ignored. Another Erase Suspend command can be written after the chip has resumed erasing. Fast Mode Set/Reset MBM29SL800TE/BE has Fast Mode function. This mode dispenses with the initial two unclock cycles required in the standard program command sequence by writing Fast Mode command into the command register. In this mode, the required bus cycle for programming is two cycles instead of four bus cycles in standard program command. The read operation is also executed after exiting this mode. During Fast mode, do not write any commands other than the Fast program/Fast mode reset command. To exit this mode, it is necessary to write Fast Mode Reset command into the command register. (Refer to the "Embedded ProgramTM Algorithm for Fast Mode" in FLOW CHART Extended algorithm.) The VCC active current is required even CE = VIH during Fast Mode. Fast Programming During Fast Mode, the programming can be executed with two bus cycles operation. The Embedded Program Algorithm is executed by writing program set-up command (A0h) and data write cycles (PA/PD) . (Refer to the "Embedded ProgramTM Algorithm for Fast Mode" in FLOW CHART Extended algorithm.) Extended Sector Protection In addition to normal sector protection, the MBM29SL800TE/BE has Extended Sector Protection as extended function. This function enable to protect sector by forcing VID on RESET pin and write a commnad sequence. Unlike conventional procedure, it is not necessary to force VID and control timing for control pins. The only RESET pin requires VID for sector protection in this mode. The extended sector protect requires VID on RESET pin. With this condition, the operation is initiated by writing the set-up command (60h) into the command register. Then, the sector addresses pins (A18, A17, A16, A15, A14, A13 and A12) and (A6, A1, A0) = (0, 1, 0) should be set to the sector to be protected (recommend to set VIL for the other addresses pins) , and write extended sector protect 18 MBM29SL800TE/BE-90/10 command (60h) . A sector is typically protected in 250 s. To verify programming of the protection circuitry, the sector addresses pins (A18, A17, A16, A15, A14, A13 and A12) and (A6, A1, A0) = (0, 1, 0) should be set and write a command (40h) . Following the command write, a logical "1" at device output DQ0 will produce for protected sector in the read operation. If the output data is logical "0", please repeat to write extended sector protect command (60h) again. To terminate the operation, it is necessary to set RESET pin to VIH.

DQ7 Data Polling The MBM29SL800TE/BE devices feature Data Polling as a method to indicate to the host that the Embedded Algorithms are in progress or completed. During the Embedded Program Algorithm an attempt to read the devices will produce the complement of the data last written to DQ7. Upon completion of the Embedded Program Algorithm, an attempt to read the device will produce the true data last written to DQ7. During the Embedded Erase Algorithm, an attempt to read the device will produce a "0" at the DQ7 output. Upon completion of the Embedded Erase Algorithm an attempt to read the device will produce a "1" at the DQ7 output. The flowchart for Data Polling (DQ7) is shown in "Data Polling Algorithm" in FLOW CHART. For chip erase and sector erase, the Data Polling is valid after the rising edge of the sixth WE pulse in the six write pulse sequence. Data Polling must be performed at sector address within any of the sectors being erased and not a protected sector. Otherwise, the status may not be valid. Once the Embedded Algorithm operation is close to being completed, the MBM29SL800TE/BE data pins (DQ7) may change asynchronously while the output enable (OE) is asserted low. This means that the devices are driving status information on DQ7 at one instant of time and then that byte's valid data at the next instant of time. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device has completed the Embedded Algorithm operation and DQ7 has a valid data, the data outputs on DQ6 to DQ0 may be still invalid. The valid data on DQ7 to DQ0 will be read on the successive read attempts. The Data Polling feature is only active during the Embedded Programming Algorithm, Embedded Erase Algorithm or sector erase time-out. (See "Hardware Sequence Flags".) 19 MBM29SL800TE/BE-90/10 See "Data Polling during Embedded Algorithm Operation Timing Diagram" in TIMING DIAGRAM for the Data Polling timing specifications and diagrams. DQ6 Toggle Bit I The MBM29SL800TE/BE also feature the "Toggle Bit I" as a method to indicate to the host system that the Embedded Algorithms are in progress or completed. During an Embedded Program or Erase Algorithm cycle, successive attempts to read (OE toggling) data from the devices will result in DQ6 toggling between one and zero. Once the Embedded Program or Erase Algorithm cycle is completed, DQ6 will stop toggling and valid data will be read on the next successive attempts. During programming, the Toggle Bit I is valid after the rising edge of the fourth WE pulse in the four write pulse sequence. For chip erase and sector erase, the Toggle Bit I is valid after the rising edge of the sixth WE pulse in the six write pulse sequence. The Toggle Bit I is active during the sector time out. In programming, if the sector being written to is protected, the toggle bit will toggle for about 2 s and then stop toggling without the data having changed. In erase, the devices will erase all the selected sectors except for the ones that are protected. If all selected sectors are protected, the chip will toggle the toggle bit for about 100 s and then drop back into read mode, having changed none of the data. Either CE or OE toggling will cause the DQ6 to toggle. In addition, an Erase Suspend/Resume command will cause the DQ6 to toggle. See "AC Waveforms for Toggle Bit I during Embedded Algorithm Operations" in TIMING DIAGRAM for the Toggle Bit I timing specifications and diagrams. DQ5 Exceeded Timing Limits DQ5 will indicate if the program or erase time has exceeded the specified limits (internal pulse count) . Under these conditions DQ5 will produce a "1". This is a failure condition which indicates that the program or erase cycle was not successfully completed. Data Polling is the only operating function of the devices under this condition. The CE circuit will partially power down the device under these conditions (to approximately 2 mA) . The OE and WE pins will control the output disable functions as described in "MBM29SL800TE/BE User Bus Operations (BYTE = VIH) " and "MBM29SL800TE/BE User Bus Operations (BYTE = VIL) " in DEVICE BUS OPERATION. The DQ5 failure condition may also appear if a user tries to program a non blank location without erasing. In this case the devices lock out and never complete the Embedded Algorithm operation. Hence, the system never reads a valid data on DQ7 bit and DQ6 never stops toggling. Once the devices have exceeded timing limits, the DQ5 bit will indicate a "1." Please note that this is not a device failure condition since the devices were incorrectly used. If this occurs, reset the device with command sequence. DQ3 Sector Erase Timer After the completion of the initial sector erase command sequence the sector erase time-out will begin. DQ3 will remain low until the time-out is complete. Data Polling and Toggle Bit are valid after the initial sector erase command sequence. If Data Polling or the Toggle Bit I indicates the device has been written with a valid erase command, DQ3 may be used to determine if the sector erase timer window is still open. If DQ3 is high ("1") the internally controlled erase cycle has begun. If DQ3 is low ("0") the device will accept additional sector erase commands. To insure 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 were high on the second status check, the command may not have been accepted. See "Hardware Sequence Flags". 20 MBM29SL800TE/BE-90/10 DQ2 Toggle Bit II This toggle bit II, along with DQ6, can be used to determine whether the devices are in the Embedded Erase Algorithm or in Erase Suspend. Successive reads from the erasing sector will cause DQ2 to toggle during the Embedded Erase Algorithm. If the devices are in the erase-suspended-read mode, successive reads from the erase-suspended sector will cause DQ2 to toggle. When the devices are in the erase-suspended-program mode, successive reads from the byte address of the non-erase suspended sector will indicate a logic "1" at the DQ2 bit. DQ6 is different from DQ2 in that DQ6 toggles only when the standard program or Erase, or Erase Suspend Program operation is in progress. The behavior of these two status bits, along with that of DQ7, is summarized as follows : For example, DQ2 and DQ6 can be used together to determine if the erase-suspend-read mode is in progress. (DQ2 toggles while DQ6 does not.) See also "Hardware Sequence Flags" and "DQ2 vs. DQ6" in TIMING DIAGRAM. Furthermore, DQ2 can also be used to determine which sector is being erased. When the device is in the erase mode, DQ2 toggles if this bit is read from an erasing sector. Reading Toggle Bits DQ6/DQ2 Whenever the system initially begins reading toggle bit status, it must read DQ7 to DQ0 at least twice in a row to determine whether a toggle bit is toggling. Typically a 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 DQ7 to DQ0 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 complete 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 begining of the algorithm when it returns to determine the status of the operation.

If the output is low, the devices are busy with either a program or erase operation. If the output is high, the devices are ready to accept any read/write or erase operation. If the MBM29SL800TE/BE are placed in an Erase Suspend mode, the RY/BY output will be high. During programming, the RY/BY pin is driven low after the rising edge of the fourth WE pulse. During an erase operation, the RY/BY pin is driven low after the rising edge of the sixth WE pulse. The RY/BY pin will indicate a busy condition during the RESET pulse. Refer to "RY/BY Timing Diagram during Program/Erase Operation Timing Diagram" and "RESET, RY/BY Timing Diagram" in TIMING DIAGRAM for a detailed timing diagram. The RY/BY pin is pulled high in standby mode. Since this is an open-drain output, the pull-up resistor needs to be connected to VCC; multiples of devices may be connected to the host system via more than one RY/BY pin in parallel. Byte/Word Configuration The BYTE pin selects the Byte (8-bit) mode or Word (16-bit) mode for the MBM29SL800TE/BE devices. When this pin is driven high, the devices operate in the Word (16-bit) mode. The data is read and programmed at DQ15 to DQ0. When this pin is driven low, the devices operate in byte (8-bit) mode. Under this mode, the DQ15/A-1 pin becomes the lowest address bit and DQ14 to DQ8 bits are tri-stated. However, the command bus cycle is always an 8-bit operation and hence commands are written at DQ7 to DQ0 and the DQ15 to DQ8 bits are ignored. Data Protection The MBM29SL800TE/BE are designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transitions. During power up the devices automatically reset the internal state machine in the Read mode. Also, with its control register architecture, alteration of the memory contents only occurs after successful completion of specific multi-bus cycle command sequences. The devices also incorporate several features to prevent inadvertent write cycles resulting form VCC power-up and power-down transitions or system noise. If Embedded Erase Algorithm is interrupted, there is possibility that the erasing sector (s) cannot be used. Write Pulse "Glitch" Protection Noise pulses of less than 3 ns (typical) on OE, CE, or WE will not initiate a write cycle. Logical Inhibit Writing is 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 Power-up of the devices with WE = CE = VIL and OE = VIH will not accept commands on the rising edge of WE. The internal state machine is automatically reset to the read mode on power-up. Sector Protection Device user is able to protect each sector individually to store and protect data. Protection circuit voids both program and erase commands that are addressed to protected sectors. Any commands to program or erase addressed to ptotected sector are ignored.
