24 MHz 8-bit core with automotive-grade peripherals
Housed in a 32-LQFP package with 25 I/O lines, this MCU is surface-mount ready for reflow assembly.
This means STMicroelectronics is not actively promoting it for new projects, and the part is on a trajectory toward end-of-life. For new designs, the procurement team should evaluate a pin-compatible or functionally equivalent replacement within the STM8A family to avoid a future last-time-buy scramble. The STM8AF6286TCY is still orderable for sustaining production, but the window for volume commitments is narrowing.
The 2 KB EEPROM provides non-volatile storage for calibration parameters and fault codes without needing an external serial EEPROM. The 10-bit ADC with 7 channels covers analog sensor inputs like temperature, position, and pressure transducers common in automotive subsystems.
