The 64-LQFP package brings out 52 I/O lines, a 16-channel 10-bit ADC, and on-chip CAN, LIN, I²C, SPI, and UART interfaces. At 24 MHz the STM8 pipeline delivers roughly 6 MIPS — enough for a body-control module polling a dozen digital inputs and driving PWM outputs for lighting or wiper motors. For time-critical CAN message handling, the 24 MHz clock keeps the bit-timing jitter within the CAN 2.0 tolerance window without a dedicated PLL. ## CAN and LIN — native bus interfaces The on-chip CAN and LIN controllers reduce BOM count in automotive body and gateway modules. ## Sourcing posture Given the NRND status, early commitment on quantity and delivery window is advised to avoid a last-minute scramble when the factory allocation closes.","metaTitle":"ST STM8AF52A9TCX 8-bit MCU, 24 MHz, 128 KB Flash, AEC-Q100","metaDescription":"STM8AF52A9TCX automotive 8-bit MCU with 24 MHz core, 128 KB Flash, 6 KB RAM, CAN/LIN, -40 to 125 °C.
