The STM8S003F3/K3 Ultra Value Series 8-bit microcontroller provides 8 KB of flash program memory and integrated true data EEPROM. They are referred to as low-density devices in the STM8S microcontroller series reference manual (RM0016). The STM8S003F3/K3 high-value series devices have the following advantages: performance, robustness, and reduced system costs. Supports real data EEPROM with up to 100000 write/erase cycles, advanced 16 MHz clock frequency advanced core and peripherals manufactured with advanced technology, powerful I/O, independent watchdog with independent clock source, and clock security system, ensuring device performance and robustness. Due to the high system integration with internal clock oscillator, watchdog, and undervoltage reset function, the system cost can be reduced.
