The STM8S103x access line 8-bit microcontrollers offer 8 Kbytes Flash program memory, plus integrated true data EEPROM. The STM8S microcontroller family reference manual (RM0016) refers to devices in this family as low-density. They provide the following benefits:

Reduced system cost Integrated true data EEPROM for up to 300 k write/erase cycles

High system integration level with internal clock oscillators, watchdog and brown-out reset.

– 16 MHz

– Robust I/O, independent watchdogs with separate clock source

Clock security system

· Full documentation and a wide choice of development tools

· Advanced core and peripherals made in a state-of-the art technology
