STMicroelectronics | STM8S103F3P3

The STM8S103F3P3 is a 8-bit Microcontroller, offers 8-Kbytes flash program memory plus integrated true data EEPROM. This provides performance, robustness, and reduced system cost.

This device performance and robustness are ensured by advanced core and peripherals made in a state-of-the art technology, a 16 MHz clock frequency, robust I/Os, independent watchdogs with separate clock source, and a clock security system.
