With 52 general-purpose I/O lines brought out to a 64-LQFP (10x10 mm) package, the part offers enough pins to capture multiple sensor inputs and drive local actuators without an external GPIO expander. The wide 3V to 5.5V supply range means it can sit directly on an automotive battery rail (with appropriate transients handled) or a regulated 3.3V logic supply. That means STMicroelectronics is not actively promoting it for new projects, though it remains available for existing production runs through the independent distribution channel.","metaTitle":"STM8AF5269TAX 8-bit MCU, 24 MHz, 32 KB Flash, AEC-Q100","metaDescription":"STMicroelectronics STM8AF5269TAX automotive 8-bit MCU with 24 MHz core, 32 KB Flash, 2K x 8 RAM, 1K x 8 EEPROM, CAN/LIN interfaces.
