The peripheral set includes a 10-channel 10-bit ADC, PWM timers, and a watchdog, plus CAN 2.0B and LIN bus interfaces for automotive network integration. This is a genuine automotive-grade part, not an industrial derivative with a temperature-range sticker — the AEC-Q100 qualification and the STM8A series designation confirm it was developed and validated to the PPAP documentation an OEM auditor will expect. ## AEC-Q100 qualification — what grade and what it means The STM8AF52A8TCX is AEC-Q100 qualified and belongs to the STM8A automotive series. ## 48-LQFP footprint — board integration note The STM8AF52A8TCX comes in a 48-pin LQFP package, surface-mount for reflow assembly. The 38 GPIO lines are distributed around the perimeter.","metaTitle":"ST STM8AF52A8TCX 8-bit MCU, AEC-Q100, 24MHz, 128KB Flash, 48-LQFP","metaDescription":"STMicroelectronics STM8AF52A8TCX automotive 8-bit MCU, AEC-Q100, 24MHz, 128KB Flash, 6KB RAM, 2KB EEPROM, CAN, LIN, -40°C to 125°C, 48-LQFP.
