Description

The STM8S105x4/6 access line 8-bit microcontrollers offer from 16 to 32 Kbyte Flash program memory, plus integrated true data EEPROM. The STM8S microcontroller family reference manual (RM0016) refers to devices in this family as medium-density. All devices of the STM8S105x4/6 access line provide the following benefits: reduced system cost, performance and robustness, short development cycles, and product longevity.
The system cost is reduced thanks to an integrated true data EEPROM for up to 300 k write/erase cycles and a high system integration level with internal clock oscillators, watchdog and brown-out reset.
Device performance is ensured by a 16 MHz CPU clock frequency and enhanced characteristics which include robust I/O, independent watchdogs (with a separate clock source), and a clock security system.
Short development cycles are guaranteed due to application scalability across common family product architecture with compatible pinout, memory map and modular peripherals.
Product longevity is ensured in the STM8S family thanks to their advanced core which is made in a state-of-the-art technology for applications with 2.95 V to 5.5 V operating supply.
Full documentation is offered as well as a wide choice of development tools.
