- Pin-to-pin compatible with extended temperature variant (vs TMS320F28335PTPQ)
Design Notes
The TMS320F28335PGFA requires separate power supplies for core (1.9V) and I/O (3.3V). Use low-dropout regulators (LDOs) with low noise for the core supply, and ensure proper decoupling with 100nF capacitors close to each VDD/VDDIO pin. A bulk capacitor (10uF) on each supply rail is recommended. Power sequencing is critical: apply I/O supply before core supply to avoid latch-up.
For the 176-pin LQFP package, use a multi-layer PCB with dedicated ground and power planes. Place the crystal oscillator and its load capacitors close to the X1/X2 pins to minimize parasitic capacitance. Keep high-speed signal traces short and avoid routing them near the ADC inputs to reduce noise coupling. Follow TI's layout guidelines in the TMS320F2833x Technical Reference Manual.
The LQFP package has a thermal resistance (theta_JA) of approximately 40Β°C/W. At 150 MHz, the device can dissipate up to 1.5W, resulting in a temperature rise of 60Β°C above ambient. Ensure adequate airflow or a heatsink for high-temperature environments. The PTPQ variant with extended temperature range is recommended for applications exceeding 85Β°C ambient.
