- Fixed-point core with 100 MHz (vs TMS320F28069PZT)
Design Notes
The TMS320F2808PZS requires a 3.3V supply for VDD and 1.8V for VDDIO (if applicable). Use separate decoupling capacitors (0.1uF and 10uF) close to each power pin. Ensure the power supply can handle the peak current during flash programming and high-speed operation. Refer to the datasheet's power supply recommendations for proper filtering.
For the 100-pin LQFP package, ensure proper PCB layout with a solid ground plane. Place decoupling capacitors as close as possible to the VDD and VSS pins. Route high-speed signals (JTAG, clock) with controlled impedance if necessary. Follow the manufacturer's layout guidelines to minimize noise and ensure reliable operation.
A common pitfall is forgetting to connect the JTAG pins (TMS, TCK, TDI, TDO) to a header for programming and debugging. Also, ensure the XRS reset pin has a proper pull-up resistor and capacitor for reliable reset. Do not leave unused GPIO pins floating; configure them as outputs or tie them to a defined state to avoid excessive current draw.
