Datasheet

Description2
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:
performance, robustness, and reduced system cost.
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.
The system cost is reduced thanks to an integrated true data EEPROM for up to 300
kwrite/erase cycles and a high system integration level with internal clock oscillators, watchdog
and brown-out reset.
Full documentation is offered as well as a wide choice of development tools.
