The STM8AF6266TCX from STMicroelectronics is an automotive 8-bit microcontroller from the STM8A family, featuring 32KB Flash, 1KB true data EEPROM (300k write/erase cycles), and 2KB RAM. Based on the STM8A core with Harvard architecture and 3-stage pipeline, it delivers up to 10 MIPS at 16MHz. Peripherals include LIN 2.2, SPI, I2C, UART, 10-bit ADC with 7 channels, and multiple 16-bit PWM timers. AEC-Q100 qualified with -40°C to +125°C operating range in a 32-pin LQFP package.

The STM8A core uses a 3-stage pipeline (fetch, decode, execute) with Harvard architecture separating program and data buses for simultaneous access. Instructions execute in an average of 1.6 cycles. The integrated EEPROM provides non-volatile data storage with 300k write/erase endurance for calibration and configuration data. The LIN 2.2 interface supports automotive local interconnect network communication with automatic resynchronization. The clock security system monitors the external oscillator and automatically switches to the internal RC if failure is detected.
