Key Differentiators
- Single-core with CLA for parallel control (vs TMS320F28377DZWTT)
- Higher MIPS than F28075 (vs TMS320F28075PZPQ)
- Functional safety support (vs TMS320F280045PZQ)
Design Notes
The TMS320F28377SZWTT requires a 1.2V core supply and 3.3V I/O supply. Use low-dropout regulators (LDOs) with low noise for the core, and ensure proper decoupling with 100nF capacitors close to each power pin. A bulk capacitor of 10uF is recommended on the main supply rails.
For the NFBGA package, use a 4-layer PCB with dedicated power and ground planes. Place the ADC reference decoupling capacitors as close as possible to the ADC pins. Follow the layout guidelines in the TI datasheet for high-speed interfaces like EMIF and PWM outputs to minimize signal integrity issues.
The NFBGA package has a thermal resistance of approximately 20Β°C/W. At maximum clock speed and full peripheral usage, the power dissipation can reach 2W, resulting in a temperature rise of 40Β°C. Ensure adequate airflow or a heatsink for operation at high ambient temperatures.
Compliance Information
RoHS compliant per TI product page. Not AEC-Q100 qualified; for automotive, consider TMS320F28377DZWTT-Q1 if available.
