Design Notes
The TMS320F28035PNT requires a 3.3V supply for I/O and an internal 1.8V core voltage. Place 100nF and 10uF decoupling capacitors close to each VDD and VDDIO pin. The core voltage is generated internally, but ensure the 3.3V supply is clean and stable. Use a low-dropout regulator (LDO) with low noise for analog sections.
For the 80-pin LQFP package, ensure proper grounding and thermal management. Connect the exposed pad (if present) to the ground plane with multiple vias. Keep high-speed signals short and use controlled impedance for clock lines. Separate analog and digital ground planes to minimize noise coupling into the ADC.
Do not exceed the absolute maximum ratings for VDD (3.6V) and VDDIO (3.6V). Ensure the ADC reference pins are properly bypassed with 1uF and 100nF capacitors. When using the internal oscillator, place the crystal close to the X1/X2 pins and load capacitors as specified in the datasheet. Avoid floating GPIO pins by configuring them as inputs with pull-ups or outputs.
Compliance Information
