64 KB of Flash leaves room for a bootloader plus two application images if you want field-upgradeable firmware over CAN. The 2 KB of EEPROM is separate from the Flash array — no wear-leveling needed for calibration constants or fault logs that change every cycle.
No official successor order code is listed in the lifecycle record. For a pin-compatible alternative within the same family, evaluate the STM8AF5288TAY — it shares the 48-LQFP package and memory map; the key difference is the temperature grade or minor spec variant. For new designs, migrate to a current STM8A or STM32 automotive MCU.
The core runs at 24 MHz, delivering roughly 20 MIPS on the STM8 pipeline — suitable for automotive body-control and sensor-fusion tasks.
It belongs to the STM8A series, which is AEC-Q100 qualified for automotive applications.
