Automotive 8-bit MCU with AEC-Q100 qualification
It runs at 16 MHz on an STM8A core, with 32 KB of Flash program memory, 2 KB of RAM, and 1 KB of EEPROM.
Memory and peripheral set for body-control tasks
The 32 KB Flash and 2 KB RAM are sized for moderate firmware loads such as window lift, wiper control, or seat-position modules. The 1 KB EEPROM stores calibration and diagnostic data without external storage. On-chip peripherals include a 7-channel 10-bit ADC, PWM outputs, brown-out detect, POR, and a watchdog timer.
NRND — sourcing reality for this order code
This means it is not the target for new design-ins, but existing production lines may still require it for BOM continuity. We source this part through independent distribution channels and quote it to order against an RFQ. For new designs, ST recommends evaluating the active STM8A family members — contact us for cross-reference support.
Package and supply range
Housed in a 32-lead LQFP (7x7 mm) for surface-mount assembly, the device operates from a 3 V to 5.5 V supply. The 25 I/O lines are enough for a typical sensor-interface or actuator-driver board.
