10/103 DS7147 Rev 10
2 Description
The STM8S003F3/K3 value line 8-bit microcontrollers offer 8 Kbytes of Flash program
memory, plus integrated true data EEPROM. They are referred to as low-density devices in
the STM8S microcontroller family reference manual (RM0016).
The STM8S003F3/K3 value line devices provide the following benefits: performance,
robustness and reduced system cost.
Device performance and robustness are ensured by true data EEPROM supporting up to
100000 write/erase cycles, advanced core and peripherals made in a state-of-the-art
technology at 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 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.
