BS003F3P6 datasheet 8S003F3P6 mcu

The STM8S003F3/K3, 8S003F3P6 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).
TheSTM8S003F3/K3, BS003F3P6 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.
