It handles CAN message processing, LIN slave tasks, and basic sensor fusion without hitting throughput limits. The 2 KB EEPROM is useful for storing calibration constants and fault codes without needing external nonvolatile memory. ## 48-LQFP footprint and supply rails The MCU is supplied in a 48-LQFP package with a 7x7 mm body, a common automotive-grade footprint. The 38 I/O lines provide adequate headroom for multiplexed displays, switch inputs, and actuator drives.","metaTitle":"STM8AF52A8TDX 8-bit MCU, 24 MHz, AEC-Q100, 128 KB Flash","metaDescription":"STMicroelectronics STM8AF52A8TDX 8-bit MCU, 24 MHz core, 128 KB Flash, 6 KB RAM, 2 KB EEPROM.
