Automotive-grade 8-bit MCU with CAN – the peripheral mix that matters
The STM8AF5288TAY is an 8-bit STM8A-core microcontroller from STMicroelectronics built for automotive body and industrial CAN-node applications. The 48-LQFP package provides 38 general-purpose I/Os.
For an existing production BOM that already qualifies this MCU, the NRND status means you can continue sourcing through the independent channel while planning a migration. For a new design, selecting this part locks you into a limited procurement window. The official STM8A series includes many pin-compatible Flash and RAM densities; a migration path within the family is the most straightforward option, but no specific successor order code is published in the lifecycle record.
24 MHz, 64 KB Flash, CAN – sizing the part for the job
The 24 MHz core speed is typical for 8-bit automotive MCUs – enough to handle a CAN message loop, LIN slave protocol, and a few control loops without external clock management (the internal oscillator is on-chip). The 64 KB Flash is sized for mid-complexity firmware: a CAN stack, bootloader, and application code fit without external memory. The 6K x 8 RAM is the tighter resource; if your application buffers multiple CAN messages or runs a real-time OS with several tasks, verify the RAM footprint early. The 10-channel 10-bit ADC is adequate for monitoring analogue sensors (temperature, position, voltage) but not for high-resolution measurement.
Package and supply – the board-level constraints
Brown-out detect and POR are integrated, so external reset supervision is optional.
