The high-density STM8AL3188 ultra-low-power devices feature an 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 high-density STM8AL3188 microcontrollers feature embedded data EEPROM and low power low-voltage single-supply program Flash memory. The devices incorporate an extensive range of enhanced I/Os and peripherals, a 12-bit ADC, two DACs, two comparators, a real-time clock, 8x40 or 4x44-segment LCD, four 16-bit timers, one 8-bit timer, as well as standard communication interfaces such as two SPIs, an I 2C interface, and three USARTs. One 8x40 or 4x44-segment LCD is available on the STM8AL3L8x devices. 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.Operating conditions Operating power supply range 1.8 V to 3.6 V (down to 1.65 V at power down) Temp. range: -40 to 85 or 125 °C Low power features 5 low power modes: Wait, Low power run (5.9 µA), Low power wait (3 µA), Active-halt with full RTC (1.4 µA), Halt (400 nA) Consumption: 200 µA/MHz+330 µA Fast wake up from Halt mode (4.7 µs) Ultra-low leakage per I/0: 50 nA Advanced STM8 core Harvard architecture and 3-stage pipeline Max freq: 16 MHz, 16 CISC MIPS peak Up to 40 external interrupt sources Reset and supply management Low power, ultra safe BOR reset with 5 programmable thresholds Ultra-low-power POR/PDR Programmable voltage detector (PVD) Clock management 32 kHz and 1-16 MHz crystal oscillators Internal 16 MHz factory-trimmed RC and 38 kHz low consumption RC Clock security system Low power RTC BCD calendar with alarm interrupt, Digital calibration with +/- 0.5ppm accuracy Advanced anti-tamper detection DMA 4 ch. for ADC, DACs, SPIs, I2C, USARTs, Timers, 1 ch
