Description
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).
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.
robustness
•
Performance andclock frequency
-
16 MHz CPU
-
Robust I/O, independent watchdogs with separate clock source
-
Clock security system
•
Short development cycles across a common family product architecture with compatible
-
Applications scalability and modular peripherals.

-
Full documentation and a wide choice of development tools
•
Product longevity and peripherals made in a state-of-the art technology
-
Advanced core
-
A family of products for applications with 2.95 to 5.5 V operating supply
