STM8AF6288TCX — automotive 8-bit MCU with 24MHz core and AEC-Q100 grade
It runs at 24MHz from an internal oscillator, with 64KB of Flash program memory, 6K x 8 of RAM, and 2K x 8 of EEPROM for data storage.
For a BOM line already qualified, the NRND tag means you have time to secure last-time-buy quantities or identify a migration path. For new automotive designs, a pin-compatible alternative within the STM8A family should be evaluated before committing the layout.
24MHz core, 64KB Flash — sizing the firmware budget
The 24MHz clock rate is typical for an 8-bit MCU handling real-time control loops — LIN bus messaging, PWM generation for lighting or small motor drives, and sensor polling via the 10-bit ADC. The 64KB Flash provides room for a modest application stack plus bootloader; the 2K x 8 EEPROM holds calibration and configuration data across power cycles without needing external storage.
