The STM8AF52A9TDY is a 8-bit Automotive Microcontroller, 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 130nm embedded non-volatile memory technology. The STM8 allows fast and safe development through enhanced stack pointer operations, advanced addressing modes and new instructions. The device offer 128kB of flash program memory and integrated true data EEPROM. Device performance is ensured by 20MIPS at 24MHz CPU clock frequency and enhanced characteristics which include robust I/O, independent watchdogs (with a separate clock source) and a clock security system.
