Key Differentiators
- AEC-Q100 automotive qualification (vs TMS320F28031)
- Higher performance than F28030 (vs TMS320F28030-Q1)
- Cost-effective without FPU (vs TMS320F28035-Q1)
Design Notes
For the TMS320F28031-Q1, ensure stable power supply with a 3.3V rail and proper decoupling. Place 0.1uF and 1uF capacitors near each power pin. Use a ferrite bead to filter high-frequency noise. The ADC reference should be carefully filtered to improve conversion accuracy. Avoid power supply glitches that could reset the MCU.
For the ADC, keep analog inputs away from digital switching signals. Use a separate analog ground plane that connects to digital ground at a single point. Route the ADC input traces with a guard ring to minimize crosstalk. Also, place the crystal oscillator close to the MCU with short traces to ensure stable clock operation.
A common mistake is not configuring the ADC trigger source properly. The ADC needs a trigger for conversion; using PWM events ensures synchronization with the control loop. Also, ensure the GPIO pins used for PWM have adequate drive strength. Wait for the flash to complete programming before resetting the device. Verify the watchdog timer configuration to avoid unexpected resets in production.
