It runs at 16 MHz, with 8 KB of Flash program memory, 1 KB of SRAM, and 640 bytes of EEPROM — enough for body-control logic, LIN-node firmware, or sensor-interface code that needs non-volatile parameter storage. The 20-TSSOP package and 16 I/O lines suit compact ECU boards or actuator modules where board area is tight. The 16 MHz core executes most ALU instructions in a single cycle. The 10-bit ADC samples at the rate specified in the datasheet. ## Automotive-grade peripherals and I/O The internal oscillator saves the external crystal BOM line, though the accuracy (±1 % over temp) does not meet precision timing for a CAN bus without a quartz. Brown-out reset and POR are built in, so the MCU starts cleanly from a 3 V to 5.5 V supply rail.","metaTitle":"ST STM8AF6223PDAX 8-bit MCU, AEC-Q100, 16 MHz, 8 KB Flash","metaDescription":"STM8AF6223PDAX automotive 8-bit MCU from STMicroelectronics. 16 MHz core, 8 KB Flash, 1 KB RAM, AEC-Q100 qualified.
