The STMicroelectronics STM8AF6288TAY is an 8-bit microcontroller from the STM8A automotive-grade family, built around the STM8 core running at 24 MHz. The 48-LQFP package gives you 38 I/O lines, a 10-channel 10-bit ADC, and serial interfaces including I²C, LINbus, SPI, and UART/USART.
That means it's still available for existing production runs, but ST is signaling that new designs should target a successor or alternate part. If you're qualifying this into a new BOM, expect a last-time-buy window and eventual phase-out. For ongoing production, sourcing through independent distribution with an RFQ is the practical path — we can quote current availability and pricing on request.
24 MHz core and memory sizing for control loops
The 24 MHz clock rate is typical for an 8-bit MCU handling real-time control loops — think LIN message handling, PWM generation for a DC motor, or polling a 10-bit ADC.
