8-bit automotive MCU with AEC-Q100 qualification
It runs at 16 MHz, packs 8 KB of Flash program memory, 2K x 8 of RAM, and 1K x 8 of EEPROM — enough for sensor fusion, LIN-bus node control, or actuator management in a body-control module. The 48-LQFP package (7x7 mm) gives you 41 I/Os, plus a 12-bit ADC with 25 channels and a single 12-bit DAC, all rated over -40°C to 125°C and AEC-Q100 qualified.
NRND — plan your BOM transition
If you are qualifying a fresh BOM, look at the active STM8A siblings in the same 48-LQFP footprint — ST does not publish a direct pin-compatible successor for this exact code, so a pin-to-pin swap requires checking the current STM8A selector guide.
The 8-bit core runs at 16 MHz, handling LIN-bus messaging, ADC sampling, and PWM generation.
Peripherals and connectivity for automotive nodes
On-chip peripherals include brown-out detect, POR, a watchdog timer, and DMA — all essential for fail-safe automotive designs. The internal oscillator saves an external crystal, though you still need a clock source for the LIN bus timing. The 25-channel 12-bit ADC covers multiple analog inputs without an external mux.
