STM8 8-bit MCUs

ST's 8-bit microcontroller platform is implemented around a high-performance 8-bit core and a state-of-the-art set of peripherals. This platform is manufactured using an ST-proprietary 130 nm embedded non-volatile memory technology.
The STM8 allows fast and safe development through enhanced stack pointer operations, advanced addressing modes and new instructions.

The 8-bit microcontroller platform supports four product series:

Your next 8-bit MCU is a 32-bit!

STM8 MCUs now available in 8-pin package!

The STM8 Series expands our product portfolio in smaller pin count packages, introducing two part numbers in a SO8 package.
