Key Differentiators
- Higher performance than TMS320F28069UPNT (vs TMS320F28069UPNT)
- Lower cost than TMS320F28335PTPS (vs TMS320F28335PTPS)
- More memory than TMS320F28334PTPS (vs TMS320F28334PTPS)
Design Notes
The TMS320F28332PTPS requires separate 1.8V core and 3.3V I/O supplies. Use low-dropout regulators (LDOs) with low noise for the core supply, and ensure proper decoupling with 100nF capacitors close to each power pin. The total current draw can reach up to 300mA on the core supply, so size the regulator accordingly.
For the 176-pin HLQFP package, ensure the exposed pad is soldered to a thermal via array to improve heat dissipation. Follow the recommended PCB layout in the TI datasheet, including proper grounding and signal routing for the ADC inputs to minimize noise. Keep analog and digital grounds separate and connect at a single point.
When using the external memory interface (EMIF), ensure timing requirements are met for the external memory devices. Also, the ADC requires a stable reference voltage; use an external reference like REF5030 for high accuracy. Avoid floating unused GPIO pins by configuring them as outputs or enabling internal pull-ups.
Compliance Information
RoHS compliant per TI product page. Not AEC-Q100 qualified; for automotive use, consider TMS320F28335 or other qualified devices.
