Product Description

Description
The STM8S103/105 access line 8-bit microcontrollers offer from 8 Kbytes up to 32 Kbytes of program memory.
All devices of the STM8S103/105 access line provide the following benefits:
● Reduced system cost
– 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
– Applications scalability across a common family product architecture with compatible pinout, memory map and and modular peripherals.
– Full documentation and a wide choice of development tools
● Product longevity
– Advanced core and peripherals made in a state-of-the art technology
– A family of products for applications with 3.0 V to 5.5 V operating supply
