Description

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.
