Product details

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.

Frequently asked questions

What is the replacement for STM8AF6223PDAU?

The official successor is not listed in the available records. The base part STM8AF6223PD (without the 'AU' suffix) is the same die and package; verify pin compatibility with ST for a direct swap. For new designs, consider a current STM8A or STM32 automotive MCU with similar peripheral set.

Is STM8AF6223PDAU AEC-Q100 qualified for automotive use?

Yes, it is part of the Automotive, AEC-Q100, STM8A series, making it suitable for production in vehicle systems including under-hood environments up to 150°C.

Does STM8AF6223PDAU have a built-in ADC?

Yes, it includes a 7-channel 10-bit ADC for analog sensor inputs.
