Key Differentiators
- Integrated CLA for true parallel control loops (vs TMS320F280036C-Q1)

- Automotive-qualified with AEC-Q100 (vs TMS320F280037)
Design Notes
Place a 10 uF and 0.1 uF ceramic capacitor close to each supply pin (VDDIO, VDD, VDDA) to ensure stable power. Use a separate analog supply with a ferrite bead to isolate clean analog power for the ADC. The internal voltage regulator requires an external capacitor on the VREG pin to maintain core voltage stability. Ensure the XRSn reset pin is routed with a pull-up resistor and a small capacitor for reliable power-on reset.
The LQFP-100 package can dissipate significant heat at high clock frequencies. Provide a ground plane underneath the package and use exposed vias to the bottom copper for enhanced thermal dissipation. In automotive environments with ambient temperatures up to 125C, monitor the junction temperature and consider a heatsink or forced airflow if the device is consuming more than 500 mW.
Avoid exceeding the absolute maximum ratings on any pin. Do not connect signals directly to the ADC input pins without clamping diodes. When using the CLA, ensure that the CLA memory is properly configured and that both CPU and CLA are prevented from writing to the same memory location simultaneously to avoid data corruption. Ensure the watchdog timer is properly managed to avoid unexpected resets in production.
