Key Differentiators
- Higher performance than TMS320F28232PTPS (vs TMS320F28232PTPS)

- Pin-compatible with higher-performance variants (vs TMS320F28335PTPS)
Design Notes
The TMS320F28332PTPS requires a 1.8V core supply and 3.3V I/O supply. Use separate voltage regulators for each rail to minimize noise coupling. Place 100nF decoupling capacitors close to each VDD and VDDIO pin, and a 10uF bulk capacitor near the power input. Ensure the power supply can handle the peak current during high-speed operation.
The 176-pin HLQFP package has an exposed pad that must be soldered to a thermal pad on the PCB for optimal heat dissipation. Use multiple vias to connect the thermal pad to a ground plane. For high-power applications, consider adding a heatsink or forced air cooling. The maximum junction temperature is 125Β°C, so calculate power dissipation and ensure adequate thermal management.
Follow the layout guidelines in the datasheet for the ADC and clock circuits. Keep analog and digital grounds separate and connect them at a single point. Place the crystal oscillator close to the X1/X2 pins and ensure proper load capacitance. Route high-speed signals away from analog inputs to reduce noise.
