The supply range spans 3 V to 5.5 V, and the operating temperature covers -40°C to 125°C, making it suitable for under-hood and engine-bay environments. Connectivity covers I²C, LINbus, SPI, and UART/USART. ## NRND — plan your BOM transition The 16 MHz core speed is adequate for real-time control loops like LIN slave nodes, sensor fusion, or brush-DC motor commutation at moderate rates. The 4 KB Flash limits firmware to small control algorithms — not suitable for complex protocol stacks or over-the-air update logic. The 640-byte EEPROM provides non-volatile storage for calibration constants or fault codes without external memory. The 5-channel 10-bit ADC covers basic analog sensing (temperature, potentiometer, current shunt) on a single package. The STM8AF6223IPCU is AEC-Q100 qualified, meeting automotive reliability standards for under-hood and cabin domains. Compliance documentation (RoHS, REACH) is available with the datasheet package. For a validated second source or successor, contact our sourcing desk — we maintain cross-reference data for this family.","metaTitle":"ST STM8AF6223IPCU 8-bit MCU, AEC-Q100, 16 MHz, 4 KB Flash, 20-TSSOP","metaDescription":"STM8AF6223IPCU 8-bit automotive MCU, 16 MHz, 4 KB Flash, 1K x 8 RAM, AEC-Q100, -40°C to 125°C.
