STM8S103F2M6 Description

The STM8S103F2M6 access line 8-bit microcontrollers provide integrated true data EEPROM and 8 Kbyte Flash program memory. Devices from this series are referred to as low-density in the STM8S microcontroller family reference manual (RM0016). They offer improved performance, increased robustness, and lower system costs.

Modernized peripherals and advanced cores, a 16 MHz clock frequency, durable I/Os, independent watchdogs with a separate clock source, and a clock security system all contribute to the performance and resilience of the device.

An integrated real data EEPROM with up to 300 k write/erase cycles and a high level of system integration with internal clock oscillators, watchdog, and brown-out reset decrease the system cost.

A large selection of development tools is available, along with comprehensive documentation.
