The STM8AF6266TCX is an automotive-grade 8-bit microcontroller from STMicroelectronics. It features a 16MHz STM8A core with 32KB flash and 2KB RAM. Operating from 3V to 5.5V, it includes brown-out reset, POR, PWM, and WDT. The 32-LQFP package is designed for reliable performance from -40°C to 125°C, making it suitable for demanding automotive and industrial applications.
- Automotive-grade reliability – AEC-Q100 qualified for harsh environments.
- Wide supply range 3V-5.5V – reduces need for external regulators.
- Integrated safety features – WDT and brown-out reset improve system robustness.
- High-temperature operation – supports 125°C ambient without derating.
Automotive Lighting Control
The 16MHz STM8A core with PWM outputs enables precise LED dimming. Its 125°C rating supports headlamp proximity.
Industrial Valve Actuators
With 32KB flash, it stores multiple calibration curves. The WDT ensures fail-safe operation in continuous processes.
Engine Management Sensors
5.5V tolerance allows direct interface to 5V sensor rails. The brown-out reset protects against cranking voltage dips.
Smart Battery Switches
POR and WDT provide safe state transitions during load switching. The 32-LQFP fits inside battery junction boxes.
Pump Control for Automotive Cooling
PWM channels drive brushless pumps efficiently. The wide temperature range covers under-hood conditions.
Off-Road Vehicle Electronics
Robust 125°C operation and 3V minimum supply handle extreme vibration and heat. The compact package suits sealed controllers.
