STMicroelectronics | STM8S105C4T6

The STM8S105C4T6 is a Mainstream access line 8-bit Microcontroller with 16 Kbytes Flash program memory, plus integrated true data EEPROM. It provides reduced system cost, performance and robustness, short development cylces, and product longevity.   

This device performance is ensured by a 16 MHz CPU clock frequency and enhanced characteristics which include robust I/O, independent watchdogs (with a separate clock source), and a clock security system.
