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
