  • The STM8S003F3/K3 value line 8-bit microcontrollers offer 8 Kbytes of Flash program memory, plus integrated true data EEPROM. They are referred to as low-density devices in the STM8S microcontroller family reference manual (RM0016).

    The STM8S003F3/K3 value line devices provide the following benefits: performance, robustness and reduced system cost.
    Device performance and robustness are ensured by true data EEPROM supporting up to 100000 write/erase cycles, advanced core and peripherals made in a state-of-the-art technology at 16 MHz clock frequency, robust I/Os, independent watchdogs with separate clock source, and a clock security system.
    The system cost is reduced thanks to a high system integration level with internal clock oscillators, watchdog, and brown-out reset.
    Full documentation is offered as well as a wide choice of development tools.

    • Analog to digital converter (ADC)
      • 10-bit ADC, ± 1 LSB ADC with up to 5 multiplexed channels, scan mode and analog watchdog
    • I/Os
      • Up to 28 I/Os on a 32-pin package including 21 high-sink outputs
      • Highly robust I/O design, immune against current injection
    • Development support
