8-bit MCU for automotive body control — what is in the kit
The 32-pin LQFP package (7x7 mm) gives you 25 I/O lines, plus a 7-channel 10-bit ADC, I²C, SPI, LIN, and UART interfaces, and built-in brown-out reset, POR, PWM, and watchdog timer.
The STM8AF6286TAX is officially obsolete per STMicroelectronics. That means no further factory orders are accepted — no last-time-buy window, no new production. If you have this part on a current BOM, you are looking at surplus or broker channels for remaining inventory. The 32-LQFP footprint and the STM8A core architecture are shared across the STM8AF series, so a pin-compatible drop-in is the first place to check.
24 MHz and the memory envelope — sizing the firmware
At 24 MHz this is a workhorse 8-bit core, not a speed demon. The 64 KB Flash and 6 KB RAM suit a single control loop with moderate data tables — think LIN-based actuator control, sensor aggregation, or a simple HMI panel. The 2 KB EEPROM is handy for storing calibration offsets or fault codes without wearing the Flash.
