The STM8AF6246UDY from STMicroelectronics is an automotive-grade 8-bit STM8A microcontroller in a 32-VFQFN package. It operates from 3V to 5.5V at 16MHz, with 16KB flash and 2KB RAM. Designed for extreme environments, it features brown-out reset, POR, PWM, and WDT, with an operating temperature range up to 150°C for under-hood automotive applications.
- 150°C operating temperature – enables placement in high-heat automotive zones.
- Automotive-grade reliability – meets AEC-Q100 standards for harsh environments.
- 3V-5.5V supply – directly powered from vehicle battery with load-dump protection.
- 32-VFQFN package – excellent thermal dissipation for high-current PWM outputs.
Engine Control Units
150°C rating allows placement near engine block, with 16MHz speed for real-time fuel injection timing.
Transmission Actuators
PWM outputs drive solenoid valves with precise duty cycle control, while WDT ensures fail-safe operation.
Brake System Sensors
Wide voltage range handles load-dump transients, and POR resets safely during cranking voltage dips.
Exhaust Aftertreatment
High-temperature capability suits NOx sensor interfaces in diesel exhaust systems.
Electric Power Steering
16KB flash stores torque assist algorithms, with PWM for motor drive and fault detection.
HVAC Blower Controllers
3V-5.5V range supports both logic and power stages, with PWM for variable speed control.
