The STM8S103F2/x3 access line 8-bit microcontroller provides 8 KB of flash program memory and integrated real data EEPROM. The STM8S microcontroller series reference manual (RM0016) refers to the devices in this series as low-density devices. They have the following advantages: performance, robustness, and reduced system costs. The advanced core and peripherals manufactured using advanced technology, 16 MHz clock frequency, robust I/O, independent watchdog with independent clock source, and clock safety system ensure device performance and robustness. Thanks to the integration of real data EEPROM with up to 300 k write/erase cycles, as well as high system integration with internal clock oscillator, watchdog, and undervoltage reset, system costs have been reduced.
