Design Notes

The TMS320F2808PZS requires a 3.3V supply for the digital core and I/O. Use a low-dropout regulator (LDO) such as the TPS7A4700 to provide a clean 3.3V rail. Place 100nF decoupling capacitors close to each VDD pin and a 10uF bulk capacitor near the power input. Ensure the ground plane is solid to minimize noise.

For the 100-pin LQFP package, use a 4-layer PCB with dedicated power and ground planes. Route high-speed signals (e.g., JTAG, PWM) with controlled impedance and keep traces short. Place the crystal oscillator close to the XTAL pins and add load capacitors as specified in the datasheet. Avoid routing sensitive analog signals near switching nodes.

Ensure the JTAG pins (TMS, TCK, TDI, TDO) are not left floating; pull them up or down as recommended. The device has an internal oscillator, but for accurate timing, use an external crystal. Also, verify the boot mode pins (GPIO18, GPIO29) are set correctly to select the desired boot source (flash, SPI, etc.).
