The medium-density STM8AL3xxx family operates from 1.8 V to 3.6 V (down to 1.65 V at power down) and is available in the -40 to +85°C and -40 to +125°C temperature ranges. The medium-density STM8AL3xxx ultra-low-power family features the enhanced STM8 CPU core providing increased processing power (up to 16 MIPS at 16 MHz) while maintaining the advantages of a CISC architecture with improved code density, a 24-bit linear addressing space and an optimized architecture for low power operations. The family includes an integrated debug module with a hardware interface (SWIM) which allows non-intrusive In-Application debugging and ultrafast Flash programming. All medium-density STM8AL3xxx microcontrollers feature embedded data EEPROM and low power low-voltage single-supply program Flash memory. They incorporate an extensive range of enhanced I/Os and peripherals. The modular design of the peripheral set allows the same peripherals to be found in different ST microcontroller families including 32-bit families. This makes any transition to a different family very easy, and simplified even more by the use of a common set of development tools. Two different packages are proposed which include 32 and 48 pins. Depending on the device chosen, different sets of peripherals are included. All STM8AL3xxx ultra-low-power products are based on the same architecture with the same memory mapping and a coherent pinout.

An internal or external interrupt, event or a Reset can be used to exit the microcontroller from Wait mode (WFE or WFI mode). Wait consumption: refer to Table 22. • Low power run mode: The CPU and the selected peripherals are running. Execution is done from RAM with a low speed oscillator (LSI or LSE). Flash and data EEPROM are stopped and the voltage regulator is configured in ultra-low-power mode. The microcontroller enters Low power run mode by software and can exit from this mode by software or by a reset. All interrupts must be masked. They cannot be used to exit the microcontroller from this mode. Low power run mode consumption: refer to Table 23. • Low power wait mode: This mode is entered when executing a Wait for event in Low power run mode. It is similar to Low power run mode except that the CPU clock is stopped. The wakeup from this mode is triggered by a Reset or by an internal or external event (peripheral event generated by the timers, serial interfaces, DMA controller (DMA1), comparators and I/O ports). When the wakeup is triggered by an event, the system goes back to Low power run mode. All interrupts must be masked. They cannot be used to exit the microcontroller from this mode. Low power wait mode consumption: refer to Table 24. • Active-halt mode: CPU and peripheral clocks are stopped, except RTC. The wakeup can be triggered by RTC interrupts, external interrupts or reset. Active-halt consumption: refer to Table 25 and Table 26. • Halt mode: CPU and peripheral clocks are stopped, the device remains powered on. The RAM content is preserved. The wakeup is triggered by an external interrupt or reset. A few peripherals have also a wakeup from Halt capability. Switching off the internal reference voltage reduces power consumption. Through software configuration it is also possible to wake up the device without waiting for the internal reference voltage wakeup time to have a fast wakeup time of 5 µs. Halt consumption: refer to Table 27.

The external power supply pins must be connected as follows: 3.3.2 • VSS1; VDD1 = 1.8 to 3.6 V, down to 1.65 V at power down: external power supply for I/Os and for the internal regulator. Provided externally through VDD1 pins, the corresponding ground pin is VSS1. • VSSA; VDDA = 1.8 V to 3.6 V, down to 1.65 V at power down: external power supplies for analog peripherals (minimum voltage to be applied to VDDA is 1.8 V when the ADC1 is used). VDDA and VSSA must be connected to VDD1 and VSS1, respectively. • VSS2; VDD2 = 1.8 V to 3.6 V, down to 1.65 V at power down: external power supplies for I/Os. VDD2 and VSS2 must be connected to VDD1 and VSS1, respectively. • VREF+; VREF- (for ADC1): external reference voltage for ADC1. Must be provided externally through VREF+ and VREF- pin. • VREF+ (for DAC): external voltage reference for DAC must be provided externally through VREF+. Power supply supervisor The STM8AL313x/4x/6x and STM8AL3L4x/6x have an integrated ZEROPOWER power-on reset (POR)/power-down reset (PDR), coupled with a brownout reset (BOR) circuitry. At power-on, BOR is always active, and ensures proper operation starting from 1.8 V. After the 1.8 V BOR threshold is reached, the option byte loading process starts, either to confirm or modify default thresholds, or to disable BOR permanently (in which case, the VDD min value at power down is 1.65 V). Five BOR thresholds are available through option bytes, starting from 1.8 V to 3 V. To reduce the power consumption in Halt mode, it is possible to automatically switch off the internal reference voltage (and consequently the BOR) in Halt mode. The device remains under reset when VDD is below a specified threshold, VPOR/PDR or VBOR, without the need for any external reset circuit. The STM8AL313x/4x/6x and STM8AL3L4x/6x feature an embedded programmable voltage detector (PVD) that monitors the VDD/VDDA power supply and compares it to the VPVD threshold. This PVD offers 7 different levels between 1.85 V and 3.05 V, chosen by software, with a step around 200 mV. An interrupt can be generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is higher than the VPVD threshold. The interrupt service routine can then generate a warning message and/or put the MCU into a safe state. The PVD is enabled by software. 16/123 DS7106 Rev 9 STM8AL313x/4x/6x STM8AL3L4x/6x 3.3.3 Functional overview Voltage regulator The medium-density STM8AL313x/4x/6x and STM8AL3L4x/6x embed an internal voltage regulator for generating the 1.8 V power supply for the core and peripherals. This regulator has two different modes: • Main voltage regulator mode (MVR) for Run, Wait for interrupt (WFI) and Wait for event (WFE) modes. • Low power voltage regulator mode (LPVR) for Halt, Active-halt, Low power run and Low power wait modes. When entering Halt or Active-halt modes, the system automatically switches from the MVR to the LPVR in order to reduce current consumption. 3.4 Clock management The clock controller distributes the system clock (SYSCLK) coming from different oscillators to the core and the peripherals. It also manages the clock gating for low-power modes and ensures clock robustness. Features • Clock prescaler: to get the best compromise between speed and current consumption the clock frequency to the CPU and peripherals can be adjusted by a programmable prescaler. • Safe clock switching: the clock sources can be changed safely on the fly in run mode through a configuration register. • Clock management: to reduce power consumption, the clock controller can stop the clock to the core, individual peripherals or memory. • System clock sources: four different clock sources can be used to drive the system clock: – 1-16 MHz High speed external crystal (HSE), – 16 MHz High speed internal RC oscillator (HSI), – 32.768 kHz Low speed external crystal (LSE), – 38 kHz Low speed internal RC (LSI). • RTC and LCD clock sources: the above four sources can be chosen to clock the RTC and the LCD, whatever the system clock. • Startup clock: After reset, the microcontroller restarts by default with an internal 2 MHz clock (HSI/8). The prescaler ratio and clock source can be changed by the application program as soon as the code execution starts. • Clock security system (CSS): This feature can be enabled by software. If a HSE clock failure occurs, the system clock is automatically switched to HSI. • Configurable main clock output (CCO): This outputs an external clock for use by the application.

Six byte locations contain the second, minute, hour (12/24 hour), week day, date, month, year, in BCD (binary coded decimal) format. Correction for 28, 29 (leap year), 30, and 31 day months are made automatically. It provides a programmable alarm and programmable periodic interrupts with wakeup from Halt capability. 18/123 • Periodic wakeup time using the 32.768 kHz LSE with the lowest resolution (of 61 µs) is from min. 122 µs to max. 3.9 s. With a different resolution, the wakeup time can reach 36 hours. • Periodic alarms based on the calendar can also be generated from every second to every year.

It supports the read-while-write (RWW): it is possible to execute the code from the program matrix while programming/erasing the data matrix. The option byte protects part of the Flash program memory from write and readout piracy. 3.8 DMA A 4-channel direct memory access controller (DMA1) offers a memory-to-memory and peripherals-from/to-memory transfer capability. The 4 channels are shared between the following IPs with DMA capability: ADC1, DAC, I2C1, SPI1, USART1, the 4 Timers. 3.9 Note: Analog-to-digital converter • 12-bit analog-to-digital converter (ADC1) with 25 channels (including 1 fast channel), temperature sensor and internal reference voltage • Conversion time down to 1 µs with fSYSCLK= 16 MHz • Programmable resolution • Programmable sampling time • Single and continuous mode of conversion • Scan capability: automatic conversion performed on a selected group of analog inputs • Analog watchdog • Triggered by timer ADC1 can be served by DMA1.

The voltage reference can be internal or external (coming from an I/O). • One comparator with fixed threshold (COMP1). • One comparator rail to rail with fast or slow mode (COMP2). The threshold can be one of the following: – DAC output, – External I/O, – Internal reference voltage or internal reference voltage sub multiple (1/4, 1/2, 3/4). The two comparators can be used together to offer a window function. They can wake up from Halt mode. 3.12 System configuration controller and routing interface The system configuration controller provides the capability to remap some alternate functions on different I/O ports. TIM4 and ADC1 DMA channels can also be remapped. The highly flexible routing interface allows application software to control the routing of different I/Os to the TIM1 timer input captures. It also controls the routing of internal analog signals to ADC1, COMP1, COMP2, DAC and the internal reference voltage VREFINT. It also provides a set of registers for efficiently managing the charge transfer acquisition sequence (see Section 3.13: Timers). 20/123 DS7106 Rev 9 STM8AL313x/4x/6x STM8AL3L4x/6x 3.13 Functional overview Timers The medium-density STM8AL313x/4x/6x and STM8AL3L4x/6x devices contain one advanced control timer (TIM1), two 16-bit general purpose timers (TIM2 and TIM3) and one 8-bit basic timer (TIM4).

It can be used for timebase generation with interrupt generation on timer overflow or for DAC trigger generation. 3.14 Watchdog timers The watchdog system is based on two independent timers providing maximum security to the applications. 3.14.1 Window watchdog timer The window watchdog (WWDG) is used to detect the occurrence of a software fault, usually generated by external interferences or by unexpected logical conditions, which cause the application program to abandon its normal sequence. 3.14.2 Independent watchdog timer The independent watchdog peripheral (IWDG) can be used to resolve processor malfunctions due to hardware or software failures. It is clocked by the internal LSI RC clock source, and thus stays active even in case of a CPU clock failure. 3.15 Beeper The beeper function outputs a signal on the BEEP pin for sound generation. The signal is in the range of 1, 2 or 4 kHz. 3.16 Communication interfaces 3.16.1 SPI The serial peripheral interface (SPI1) provides half/ full duplex synchronous serial communication with external devices.

At power-up, the PA1/NRST pin is a reset input pin with pull-up. It is used as a general purpose pin (PA1) and can be configured only as output push-pull, not as output open drain or as a general purpose input. Refer to Section Configuring NRST/PA1 pin as general purpose output in STM8L051/L052 Value Line, STM8L151/L152, STM8L162, STM8AL31, STM8AL3L MCU lines reference manual (RM0031). 2. Available on STM8AL3Lxx devices only. 3. In the 3.6 V tolerant I/Os, protection diode to VDD is not implemented. 4. [ ] Alternate function remapping option (if the same alternate function is shown twice, it indicates an exclusive choice not a duplication of the function). 5. In the 5 V tolerant I/Os, protection diode to VDD is not implemented. 6. A pull-up is applied to PB0 and PB4 during the reset phase. These two pins are input floating after reset release. 7. In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer, weak pull-up and protection diode to VDD are not implemented). 8. Available on STM8AL31xx devices only. 9. The PA0 pin is in input pull-up during the reset phase and after reset release. 10. High sink LED driver capability available on PA0. Note: 34/123 The slope control of all GPIO pins, except true open drain pins, can be programmed. By default, the slope control is limited to 2 MHz.

The Low power wait mode is entered when executing a WFE instruction in Low power run mode. In WFE mode, the interrupt is served if it has been previously enabled. After processing the interrupt, the processor goes back to WFE mode. When the interrupt is configured as a wakeup event, the CPU wakes up and resumes processing. 2. The interrupt from PVD is logically OR-ed with Port E and F interrupts. Register EXTI_CONF allows to select between Port E and Port F interrupt (see External interrupt port select register (EXTI_CONF) in STM8L051/L052 Value Line, STM8L151/L152, STM8L162, STM8AL31, STM8AL3L MCU lines reference manual (RM0031). 3. The device is woken up from Halt or Active-halt mode only when the address received matches the interface address. 54/123 DS7106 Rev 9 STM8AL313x/4x/6x STM8AL3L4x/6x 7 Option bytes Option bytes Option bytes contain configurations for device hardware features as well as the memory protection of the device.

The 96 bits of the identifier can never be altered by the user. The unique device identifier can be read in single bytes and may then be concatenated using a custom algorithm. The unique device identifier is ideally suited: • For use as serial numbers • For use as security keys to increase the code security in the program memory while using and combining this unique ID with software cryptographic primitives and protocols before programming the internal memory. • To activate secure boot processes Table 14.

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, out of spec current injection on adjacent pins or other functional failure (for example reset, oscillator frequency deviation, LCD levels, etc.). The test results are given in the following table. 80/123 DS7106 Rev 9 STM8AL313x/4x/6x STM8AL3L4x/6x Electrical parameters Table 40.

Functional EMS (electromagnetic susceptibility) Based on a simple running application on the product (toggling 2 LEDs through I/O ports), the product is stressed by two electromagnetic events until a failure occurs (indicated by the LEDs). • ESD: Electrostatic discharge (positive and negative) is applied on all pins of the device until a functional disturbance occurs. This test conforms to the ANSI/ESDA/JEDEC JS001, JESD22-A115 and ANSI/ESD S5.3.1. • 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 conforms with the IEC 61000 standard. A device reset allows normal operations to be resumed. The test results are given in the table below based on the EMS levels and classes defined in application note AN1709. Designing hardened software to avoid noise problems EMC characterization and optimization are performed at component level with a typical application environment and simplified MCU software. 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. 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). Table 61.

The maximum chip-junction temperature, TJmax, in degree Celsius, may be calculated using the following equation: TJmax = TAmax + (PDmax x ΘJA) Where: • TAmax is the maximum ambient temperature in °C • ΘJA is the package junction-to-ambient thermal resistance in °C/W • PDmax is the sum of PINTmax and PI/Omax (PDmax = PINTmax + PI/Omax) • PINTmax is the product of IDD and VDD, expressed in Watts. This is the maximum chip internal power. • PI/Omax represents the maximum power dissipation on output pins Where: PI/Omax = Σ(VOL*IOL) + Σ((VDD-VOH)*I OH), taking into account the actual VOL/IOL and VOH/IOH of the I/Os at low and high level in the application.
