DocID024849 Rev 3 11/91 23 Functional overview STM32F030x4/x6/x8/xC 3 Functional overview 3.1 ARM(R)-Cortex(R)-M0 core with embedded Flash and SRAM The ARM(R) Cortex(R)-M0 processor is the latest generation of ARM processors for embedded systems. It has been developed to provide a low-cost platform that meets the needs of MCU implementation, with a reduced pin count and low-power consumption, while delivering outstanding computational performance and an advanced system response to interrupts. The ARM(R) Cortex(R)-M0 32-bit RISC processor features exceptional code-efficiency, delivering the high-performance expected from an ARM core in the memory size usually associated with 8- and 16-bit devices. The STM32F0xx family has an embedded ARM core and is therefore compatible with all ARM tools and software. Figure 3 shows the general block diagram of the device family. 3.2 Memories The device has the following features: * 4 to 32 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait states and featuring embedded parity checking with exception generation for failcritical applications. * The non-volatile memory is divided into two arrays: - 16 to 256 Kbytes of embedded Flash memory for programs and data - Option bytes The option bytes are used to write-protect the memory (with 4 KB granularity) and/or readout-protect the whole memory with the following options: 3.3 - Level 0: no readout protection - Level 1: memory readout protection, the Flash memory cannot be read from or written to if either debug features are connected or boot in RAM is selected - Level 2: chip readout protection, debug features (Cortex(R)-M0 serial wire) and boot in RAM selection disabled Boot modes At startup, the boot pin and boot selector option bit are used to select one of the three boot options: * Boot from User Flash * Boot from System Memory * Boot from embedded SRAM The boot loader is located in System Memory. It is used to reprogram the Flash memory by using USART on pins PA14/PA15 or PA9/PA10. 12/91 DocID024849 Rev 3 STM32F030x4/x6/x8/xC 3.4 Functional overview Cyclic redundancy check calculation unit (CRC) The CRC (cyclic redundancy check) calculation unit is used to get a CRC code using a configurable generator polynomial value and size. Among other applications, CRC-based techniques are used to verify data transmission or storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of the software during runtime, to be compared with a reference signature generated at linktime and stored at a given memory location. 3.5 Power management 3.5.1 Power supply schemes * VDD = 2.4 to 3.6 V: external power supply for I/Os and the internal regulator. Provided externally through VDD pins. * VDDA = from VDD to 3.6 V: external analog power supply for ADC, Reset blocks, RCs and PLL. The VDDA voltage level must be always greater or equal to the VDD voltage level and must be provided first. For more details on how to connect power pins, refer to Figure 12: Power supply scheme. 3.5.2 Power supply supervisors The device has integrated power-on reset (POR) and power-down reset (PDR) circuits. They are always active, and ensure proper operation above a threshold of 2 V. The device remains in reset mode when the monitored supply voltage is below a specified threshold, VPOR/PDR, without the need for an external reset circuit. 3.5.3 * The POR monitors only the VDD supply voltage. During the startup phase it is required that VDDA should arrive first and be greater than or equal to VDD. * The PDR monitors both the VDD and VDDA supply voltages, however the VDDA power supply supervisor can be disabled (by programming a dedicated Option bit) to reduce the power consumption if the application design ensures that VDDA is higher than or equal to VDD. Voltage regulator The regulator has two operating modes and it is always enabled after reset. * Main (MR) is used in normal operating mode (Run). * Low power (LPR) can be used in Stop mode where the power demand is reduced. In Standby mode, it is put in power down mode. In this mode, the regulator output is in high impedance and the kernel circuitry is powered down, inducing zero consumption (but the contents of the registers and SRAM are lost). DocID024849 Rev 3 13/91 23 Functional overview 3.5.4 STM32F030x4/x6/x8/xC Low-power modes The STM32F030x4/x6/x8/xC microcontrollers support three low-power modes to achieve the best compromise between low power consumption, short startup time and available wakeup sources: * Sleep mode In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can wake up the CPU when an interrupt/event occurs. * Stop mode Stop mode achieves very low power consumption while retaining the content of SRAM and registers. All clocks in the 1.8 V domain are stopped, the PLL, the HSI RC and the HSE crystal oscillators are disabled. The voltage regulator can also be put either in normal or in low power mode. The device can be woken up from Stop mode by any of the EXTI lines. The EXTI line source can be one of the 16 external lines and RTC. * Standby mode The Standby mode is used to achieve the lowest power consumption. The internal voltage regulator is switched off so that the entire 1.8 V domain is powered off. The PLL, the HSI RC and the HSE crystal oscillators are also switched off. After entering Standby mode, SRAM and register contents are lost except for registers in the RTC domain and Standby circuitry. The device exits Standby mode when an external reset (NRST pin), an IWDG reset, a rising edge on the WKUP pins, or an RTC event occurs. Note: The RTC, the IWDG, and the corresponding clock sources are not stopped by entering Stop or Standby mode. 3.6 Clocks and startup System clock selection is performed on startup, however the internal RC 8 MHz oscillator is selected as default CPU clock on reset. An external 4-32 MHz clock can be selected, in which case it is monitored for failure. If failure is detected, the system automatically switches back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full interrupt management of the PLL clock entry is available when necessary (for example on failure of an indirectly used external crystal, resonator or oscillator). Several prescalers allow the application to configure the frequency of the AHB and the APB domains. The maximum frequency of the AHB and the APB domains is 48 MHz. 14/91 DocID024849 Rev 3 STM32F030x4/x6/x8/xC Functional overview Figure 2.

Applies to STM32F030xC devices. 3.7 General-purpose inputs/outputs (GPIOs) Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog alternate functions. DocID024849 Rev 3 15/91 23 Functional overview STM32F030x4/x6/x8/xC The I/O configuration can be locked if needed following a specific sequence in order to avoid spurious writing to the I/Os registers. 3.8 Direct memory access controller (DMA) The 5-channel general-purpose DMA manages memory-to-memory, peripheral-to-memory and memory-to-peripheral transfers. The DMA supports circular buffer management, removing the need for user code intervention when the controller reaches the end of the buffer. Each channel is connected to dedicated hardware DMA requests, with support for software trigger on each channel. Configuration is made by software and transfer sizes between source and destination are independent. The DMA can be used with the main peripherals: SPI, I2C, USART, all TIMx timers (except TIM14) and ADC. 3.9 Interrupts and events 3.9.1 Nested vectored interrupt controller (NVIC) The STM32F0xx family embeds a nested vectored interrupt controller able to handle up to 32 maskable interrupt channels (not including the 16 interrupt lines of Cortex(R)-M0) and 4 priority levels. * Closely coupled NVIC gives low latency interrupt processing * Interrupt entry vector table address passed directly to the core * Closely coupled NVIC core interface * Allows early processing of interrupts * Processing of late arriving higher priority interrupts * Support for tail-chaining * Processor state automatically saved * Interrupt entry restored on interrupt exit with no instruction overhead This hardware block provides flexible interrupt management features with minimal interrupt latency. 3.9.2 Extended interrupt/event controller (EXTI) The extended interrupt/event controller consists of 32 edge detector lines used to generate interrupt/event requests and wake-up the system. Each line can be independently configured to select the trigger event (rising edge, falling edge, both) and can be masked independently. A pending register maintains the status of the interrupt requests. The EXTI can detect an external line with a pulse width shorter than the internal clock period. Up to 55 GPIOs can be connected to the 16 external interrupt lines. 16/91 DocID024849 Rev 3 STM32F030x4/x6/x8/xC 3.10 Functional overview Analog to digital converter (ADC) The 12-bit analog to digital converter has up to 16 external and two internal (temperature sensor, voltage reference measurement) channels and performs conversions in single-shot or scan modes. In scan mode, automatic conversion is performed on a selected group of analog inputs. The ADC can be served by the DMA controller. An analog watchdog feature allows very precise monitoring of the converted voltage of one, some or all selected channels. An interrupt is generated when the converted voltage is outside the programmed thresholds. 3.10.1 Temperature sensor The temperature sensor (TS) generates a voltage VSENSE that varies linearly with temperature. The temperature sensor is internally connected to the ADC_IN16 input channel which is used to convert the sensor output voltage into a digital value. The sensor provides good linearity but it has to be calibrated to obtain good overall accuracy of the temperature measurement. As the offset of the temperature sensor varies from chip to chip due to process variation, the uncalibrated internal temperature sensor is suitable for applications that detect temperature changes only. To improve the accuracy of the temperature sensor measurement, each device is individually factory-calibrated by ST. The temperature sensor factory calibration data are stored by ST in the system memory area, accessible in read-only mode. Table 3.

VREFINT is internally connected to the ADC_IN17 input channel. The precise voltage of VREFINT is individually measured for each part by ST during production test and stored in the system memory area. It is accessible in read-only mode. Table 4.

Available on STM32F030xC devices only 3.11.1 Advanced-control timer (TIM1) The advanced-control timer (TIM1) can be seen as a three-phase PWM multiplexed on six channels. It has complementary PWM outputs with programmable inserted dead times. It can also be seen as a complete general-purpose timer. The four independent channels can be used for: * Input capture * Output compare * PWM generation (edge or center-aligned modes) * One-pulse mode output If configured as a standard 16-bit timer, it has the same features as the TIMx timer. If configured as the 16-bit PWM generator, it has full modulation capability (0-100%). The counter can be frozen in debug mode. Many features are shared with those of the standard timers which have the same architecture. The advanced control timer can therefore work together with the other timers via the Timer Link feature for synchronization or event chaining. 18/91 DocID024849 Rev 3 STM32F030x4/x6/x8/xC 3.11.2 Functional overview General-purpose timers (TIM3, TIM14..17) There are four or five synchronizable general-purpose timers embedded in the STM32F030x4/x6/x8/xC devices (see Table 5 for differences). Each general-purpose timer can be used to generate PWM outputs, or as simple time base. TIM3 STM32F030x4/x6/x8/xC devices feature one synchronizable 4-channel general-purpose timer. TIM3 is based on a 16-bit auto-reload up/downcounter and a 16-bit prescaler. It features four independent channels each for input capture/output compare, PWM or one-pulse mode output. This gives up to 12 input captures/output compares/PWMs on the largest packages. The TIM3 general-purpose timer can work with the TIM1 advanced-control timer via the Timer Link feature for synchronization or event chaining. TIM3 has an independent DMA request generation. This timer is capable of handling quadrature (incremental) encoder signals and the digital outputs from 1 to 3 hall-effect sensors. The counter can be frozen in debug mode. TIM14 This timer is based on a 16-bit auto-reload upcounter and a 16-bit prescaler. TIM14 features one single channel for input capture/output compare, PWM or one-pulse mode output. Its counter can be frozen in debug mode. TIM15, TIM16 and TIM17 These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler. TIM15 has two independent channels, whereas TIM16 and TIM17 feature one single channel for input capture/output compare, PWM or one-pulse mode output. The TIM15, TIM16 and TIM17 timers can work together, and TIM15 can also operate withTIM1 via the Timer Link feature for synchronization or event chaining. TIM15 can be synchronized with TIM16 and TIM17. TIM15, TIM16 and TIM17 have a complementary output with dead-time generation and independent DMA request generation. Their counters can be frozen in debug mode. 3.11.3 Basic timers TIM6 and TIM7 These timers can be used as a generic 16-bit time base. 3.11.4 Independent watchdog (IWDG) The independent watchdog is based on an 8-bit prescaler and 12-bit downcounter with user-defined refresh window. It is clocked from an independent 40 kHz internal RC and as it operates independently from the main clock, it can operate in Stop and Standby modes. It DocID024849 Rev 3 19/91 23 Functional overview STM32F030x4/x6/x8/xC can be used either as a watchdog to reset the device when a problem occurs, or as a free running timer for application timeout management. It is hardware or software configurable through the option bytes. The counter can be frozen in debug mode. 3.11.5 System window watchdog (WWDG) The system window watchdog is based on a 7-bit downcounter that can be set as free running. It can be used as a watchdog to reset the device when a problem occurs. It is clocked from the APB clock (PCLK). It has an early warning interrupt capability and the counter can be frozen in debug mode. 3.11.6 SysTick timer This timer is dedicated to real-time operating systems, but could also be used as a standard down counter. It features: 3.12 * A 24-bit down counter * Autoreload capability * Maskable system interrupt generation when the counter reaches 0 * Programmable clock source (HCLK or HCLK/8) Real-time clock (RTC) The RTC is an independent BCD timer/counter. Its main features are the following: * Calendar with subseconds, seconds, minutes, hours (12 or 24 format), week day, date, month, year, in BCD (binary-coded decimal) format. * Automatic correction for 28, 29 (leap year), 30, and 31 day of the month. * Programmable alarm with wake up from Stop and Standby mode capability. * Periodic wakeup unit with programmable resolution and period. * On-the-fly correction from 1 to 32767 RTC clock pulses. This can be used to synchronize the RTC with a master clock. * Digital calibration circuit with 1 ppm resolution, to compensate for quartz crystal inaccuracy. * Tow anti-tamper detection pins with programmable filter. The MCU can be woken up from Stop and Standby modes on tamper event detection. * Timestamp feature which can be used to save the calendar content. This function can be triggered by an event on the timestamp pin, or by a tamper event. The MCU can be woken up from Stop and Standby modes on timestamp event detection. * Reference clock detection: a more precise second source clock (50 or 60 Hz) can be used to enhance the calendar precision. The RTC clock sources can be: 20/91 * A 32.768 kHz external crystal * A resonator or oscillator * The internal low-power RC oscillator (typical frequency of 40 kHz) * The high-speed external clock divided by 32 DocID024849 Rev 3 STM32F030x4/x6/x8/xC 3.13 Functional overview Inter-integrated circuit interfaces (I2C) Up to two I2C interfaces (I2C1 and I2C2) can operate in multimaster or slave modes. Both can support Standard mode (up to 100 kbit/s) or Fast mode (up to 400 kbit/s). I2C1 also supports Fast Mode Plus (up to 1 Mbit/s), with 20 mA output drive. Both support 7-bit and 10-bit addressing modes, multiple 7-bit slave addresses (two addresses, one with configurable mask). They also include programmable analog and digital noise filters. Table 6.

Data based on characterization results, design simulation and/or technology characteristics are indicated in the table footnotes and are not tested in production. Based on characterization, the minimum and maximum values refer to sample tests and represent the mean value plus or minus three times the standard deviation (mean 3). 6.1.2 Typical values Unless otherwise specified, typical data are based on TA = 25 C, VDD = VDDA = 3.3 V. They are given only as design guidelines and are not tested. Typical ADC accuracy values are determined by characterization of a batch of samples from a standard diffusion lot over the full temperature range, where 95% of the devices have an error less than or equal to the value indicated (mean 2). 6.1.3 Typical curves Unless otherwise specified, all typical curves are given only as design guidelines and are not tested. 6.1.4 Loading capacitor The loading conditions used for pin parameter measurement are shown in Figure 10. 6.1.5 Pin input voltage The input voltage measurement on a pin of the device is described in Figure 11.

This current consumption must be correctly distributed over all I/Os and control pins. The total output current must not be sunk/sourced between two consecutive power supply pins referring to high pin count QFP packages. 3. A positive injection is induced by VIN > VDDIOx while a negative injection is induced by VIN < VSS. IINJ(PIN) must never be exceeded. Refer to Table 18: Voltage characteristics for the maximum allowed input voltage values. 4. Positive injection is not possible on these I/Os and does not occur for input voltages lower than the specified maximum value. 5. On these I/Os, a positive injection is induced by VIN > VDDA. Negative injection disturbs the analog performance of the device. See note (2) below Table 52: ADC accuracy. 6. When several inputs are submitted to a current injection, the maximum IINJ(PIN) is the absolute sum of the positive and negative injected currents (instantaneous values). Table 20.

I/O static current consumption All the I/Os used as inputs with pull-up generate current consumption when the pin is externally held low. The value of this current consumption can be simply computed by using the pull-up/pull-down resistors values given in Table 46: I/O static characteristics. For the output pins, any external pull-down or external load must also be considered to estimate the current consumption. Additional I/O current consumption is due to I/Os configured as inputs if an intermediate voltage level is externally applied. This current consumption is caused by the input Schmitt trigger circuits used to discriminate the input value. Unless this specific configuration is required by the application, this supply current consumption can be avoided by configuring these I/Os in analog mode. This is notably the case of ADC input pins which should be configured as analog inputs. Caution: Any floating input pin can also settle to an intermediate voltage level or switch inadvertently, as a result of external electromagnetic noise. To avoid current consumption related to floating pins, they must either be configured in analog mode, or forced internally to a definite digital value. This can be done either by using pull-up/down resistors or by configuring the pins in output mode. I/O dynamic current consumption In addition to the internal peripheral current consumption measured previously, the I/Os used by an application also contribute to the current consumption. When an I/O pin switches, it uses the current from the I/O supply voltage to supply the I/O pin circuitry and to charge/discharge the capacitive load (internal or external) connected to the pin: I SW = V DDIOx x f SW x C DocID024849 Rev 3 49/91 74 Electrical characteristics STM32F030x4/x6/x8/xC where ISW is the current sunk by a switching I/O to charge/discharge the capacitive load VDDIOx is the I/O supply voltage fSW is the I/O switching frequency C is the total capacitance seen by the I/O pin: C = CINT + CEXT + CS CS is the PCB board capacitance including the pad pin.

The device goes in low-power mode after the WFE (Wait For Event) instruction, in the case of a WFI (Wait For Interruption) instruction, 16 CPU cycles must be added to the following timings due to the interrupt latency in the Cortex M0 architecture. The SYSCLK clock source setting is kept unchanged after wakeup from Sleep mode. During wakeup from Stop or Standby mode, SYSCLK takes the default setting: HSI 8 MHz. The wakeup source from Sleep and Stop mode is an EXTI line configured in event mode. The wakeup source from Standby mode is the WKUP1 pin (PA0). All timings are derived from tests performed under the ambient temperature and supply voltage conditions summarized in Table 21: General operating conditions. 50/91 DocID024849 Rev 3 STM32F030x4/x6/x8/xC Electrical characteristics Table 30.

CL1 and CL2 are usually the same size. The crystal manufacturer typically specifies a load capacitance which is the series combination of CL1 and CL2. PCB and MCU pin capacitance must be included (10 pF can be used as a rough estimate of the combined pin and board capacitance) when sizing CL1 and CL2.

Functional EMS (electromagnetic susceptibility) While a simple application is executed on the device (toggling 2 LEDs through I/O ports). the device is stressed by two electromagnetic events until a failure occurs. The failure is indicated by the LEDs: * Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard. * FTB: A Burst of Fast Transient voltage (positive and negative) is applied to VDD and VSS through a 100 pF capacitor, until a functional disturbance occurs. This test is compliant with the IEC 61000-4-4 standard. A device reset allows normal operations to be resumed. The test results are given in Table 41. They are based on the EMS levels and classes defined in application note AN1709. Table 41.

It should be noted that good EMC performance is highly dependent on the user application and the software in particular. Therefore it is recommended that the user applies EMC software optimization and prequalification tests in relation with the EMC level requested for his application. Software recommendations DocID024849 Rev 3 57/91 74 Electrical characteristics STM32F030x4/x6/x8/xC The software flowchart must include the management of runaway conditions such as: * Corrupted program counter * Unexpected reset * Critical Data corruption (control registers...) Prequalification trials Most of the common failures (unexpected reset and program counter corruption) can be reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1 second. To complete these trials, ESD stress can be applied directly on the device, over the range of specification values. When unexpected behavior is detected, the software can be hardened to prevent unrecoverable errors occurring (see application note AN1015). Electromagnetic Interference (EMI) The electromagnetic field emitted by the device are monitored while a simple application is executed (toggling 2 LEDs through the I/O ports). This emission test is compliant with IEC 61967-2 standard which specifies the test board and the pin loading. Table 42.

However, in order to give an indication of the robustness of the microcontroller in cases when abnormal injection accidentally happens, susceptibility tests are performed on a sample basis during device characterization. Functional susceptibility to I/O current injection While a simple application is executed on the device, the device is stressed by injecting current into the I/O pins programmed in floating input mode. While current is injected into the I/O pin, one at a time, the device is checked for functional failures. The failure is indicated by an out of range parameter: ADC error above a certain limit (higher than 5 LSB TUE), out of conventional limits of induced leakage current on adjacent pins (out of the -5 A/+0 A range) or other functional failure (for example reset occurrence or oscillator frequency deviation).

ADC DC accuracy values are measured after internal calibration. 2. ADC Accuracy vs. Negative Injection Current: Injecting negative current on any of the standard (non-robust) analog input pins should be avoided as this significantly reduces the accuracy of the conversion being performed on another analog input. It is recommended to add a Schottky diode (pin to ground) to standard analog pins which may potentially inject negative current. Any positive injection current within the limits specified for IINJ(PIN) and IINJ(PIN) in Section 6.3.14 does not affect the ADC accuracy. 3.

Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the pad capacitance (roughly 7 pF). A high Cparasitic value will downgrade conversion accuracy. To remedy this, fADC should be reduced. General PCB design guidelines Power supply decoupling should be performed as shown in Figure 12: Power supply scheme. The 10 nF capacitor should be ceramic (good quality) and it should be placed as close as possible to the chip.

The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated using the following equation: TJ max = TA max + (PD max x JA) Where: * TA max is the maximum ambient temperature in C, * JA is the package junction-to-ambient thermal resistance, in C/W, * PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax), * PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip internal power. PI/O max represents the maximum power dissipation on output pins where: PI/O max = (VOL x IOL) + ((VDD - VOH) x IOH), taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the application.
