The STMicroelectronics STM8AF52A8TDX is an automotive-grade 8-bit MCU with a 24MHz STM8A core. It provides 128KB of flash and 6KB of SRAM, operating from 3V to 5.5V. Housed in a 48-LQFP package, it features PWM, Brown-out Reset, POR, and WDT, and is rated for -40°C to 150°C, making it ideal for harsh automotive environments.
- Automotive temperature range (-40°C to 150°C): Meets AEC-Q100 Grade 0 requirements for engine bay applications.
- High flash density (128KB): Stores complex control algorithms and calibration data without external memory.
- Integrated PWM timers: Directly drives motors and actuators, reducing external components.
- Wide supply voltage (3-5.5V): Tolerates automotive battery fluctuations and cold-crank conditions.
Engine Control Units (ECU)
The 150°C rating and 24MHz STM8A core handle real-time fuel injection timing and ignition control, while the 5.5V supply tolerates load-dump transients.
Transmission Control Modules
With 128KB flash for calibration tables and PWM outputs for solenoid valves, this MCU manages gear shifting with high precision.
Body Control Modules
The 48-LQFP package and 3-5.5V range simplify integration with interior lighting, window motors, and central locking systems.
Electric Power Steering
The 24MHz speed and PWM channels enable smooth motor commutation, while the WDT ensures fail-safe operation in safety-critical systems.
HVAC Blower Control
Its robust temperature range and PWM capabilities allow direct control of brushless DC fans in automotive HVAC units.
Motorcycle Engine Management
The compact 48-LQFP and 128KB flash make it ideal for small-displacement engine ECUs with fuel injection and ignition control.
