The STM8S105xx access line 8-bit microcontrollers offer from 16 to 32 Kbytes Flash program memory, plus integrated true data EEPROM. They are referred to as medium-density devices in the STM8S microcontroller family reference manual (RM0016).

STM8S105xx主要优势:

All devices of the STM8S105xx access line 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.

• Performance and robustness

- 16 MHz CPU clock frequency

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

- Clock security system

• Short development cycles
