Design Notes
The TMS320F28035PAGT requires a 3.3V supply for I/O and an internal 1.8V core voltage generated by the on-chip regulator. Ensure the 3.3V rail is clean and adequately decoupled with 100nF and 10uF capacitors near the VDDIO pins. The internal regulator's output should be bypassed with a 1uF capacitor on the VDD pin. Avoid exceeding the absolute maximum ratings of 3.6V on VDDIO.
For optimal ADC performance, route analog input traces away from digital switching signals and use a solid ground plane. Place the ADC reference pins (VREFHI/VREFLO) with appropriate filtering capacitors. The crystal oscillator pins (X1/X2) should have short traces and proper load capacitors as specified in the datasheet. Use a 4-layer PCB with dedicated power and ground planes for best noise immunity.
A common mistake is neglecting the CLA's memory access conflicts. When both the CPU and CLA access the same memory block, wait states are inserted, degrading performance. Use the CLA's dedicated memory regions or implement proper semaphore handling. Also, ensure the boot mode pins are configured correctly to avoid unexpected boot behavior. Finally, verify the flash programming voltage and timing to prevent corruption.
