- Cost-effective without InstaSPIN (vs TMS320F28069MPNT)
Design Notes
The TMS320F28069UPNT has an internal voltage regulator that allows single-rail operation, but it requires external capacitors on the VREG pins as specified in the datasheet. Ensure a clean 3.3V supply with adequate decoupling (e.g., 0.1uF and 10uF capacitors) on VDDIO and VDD pins to prevent noise-induced resets.
For the 80-pin LQFP package, ensure proper thermal management by providing a solid ground plane and thermal vias under the exposed pad (if present). The LQFP package has a theta_JA of approximately 40Β°C/W, so for high-power applications, consider airflow or a heatsink. Keep high-speed signal traces short and avoid routing near the crystal oscillator pins.
A common pitfall is forgetting to connect the VCU and CLA power pins correctly. Also, ensure the boot mode pins are set correctly for the desired boot source (e.g., flash, SPI, SCI). Incorrect boot configuration can cause the MCU to fail to start. Refer to the datasheet's boot ROM table for proper pin strapping.
