150°C-rated 8-bit MCU for under-hood and high-temp automotive
It runs at a 16 MHz core speed and packs 8 KB of Flash program memory, 1K x 8 of RAM, and 640 x 8 of EEPROM — enough for sensor interfacing, LIN-bus communication, and local control loops in engine bay or transmission applications.
NRND — plan a replacement for production
For existing BOM lines, secure a last-time-buy window or qualify a pin-compatible alternative. The STM8AF6223PD (without the 'AU' suffix) is the same base part; verify the exact variant with your ST contact for a drop-in replacement.
16 MHz core, 8 KB Flash, 7-channel 10-bit ADC
With 16 I/O lines in a 20-TSSOP, it fits basic sensor-to-LIN gateway or actuator driver roles.
