Design Notes
The TMS320F2808PZA requires separate 1.8V core and 3.3V I/O supplies. Use low-dropout regulators (LDOs) with low noise for the core supply to ensure stable operation. Decouple each supply pin with a 0.1uF ceramic capacitor placed close to the pin, and add a 10uF bulk capacitor at the power entry point. Proper power sequencing is recommended: apply 3.3V I/O before or simultaneously with 1.8V core to avoid latch-up.
For the 100-pin LQFP package, ensure adequate ground plane and thermal vias under the exposed pad (if present) to dissipate heat. Route high-speed signals such as JTAG and PWM with controlled impedance and minimal trace length. Keep analog and digital grounds separate and connect at a single point to reduce noise. Follow TI's layout guidelines in the datasheet for optimal performance.
A common mistake is neglecting the 128-bit security key/lock feature, which can permanently lock the device if not handled correctly. Always back up the code and use the unlock sequence as described in the datasheet. Also, ensure the JTAG pins are not left floating; pull them up or down as recommended to prevent unintended debug mode entry.
