- Integrated Control Law Accelerator (CLA) (vs TMS320F28032PNT)
Design Notes
The TMS320F28034PNT requires a 3.3V I/O supply and an internal 1.8V core supply. Use a low-dropout regulator (LDO) to generate the 3.3V from a higher rail, and ensure the internal 1.8V regulator is properly decoupled with 1uF and 0.1uF capacitors as specified in the datasheet. Place decoupling capacitors close to the VDDIO and VDD pins to minimize noise.
For the LQFP-80 package, ensure proper grounding and power plane design. Use a solid ground plane and split power planes for 3.3V and 1.8V if necessary. Route JTAG signals with controlled impedance and keep them short to avoid signal integrity issues. Follow the layout guidelines in the TI datasheet for optimal performance.
A common pitfall is forgetting to connect the JTAG pins correctly, which prevents programming and debugging. Ensure the JTAG pins (TMS, TCK, TDI, TDO) are pulled up or down as required. Also, verify the crystal oscillator circuit (X1/X2) with appropriate load capacitors. Incorrect crystal setup can cause the MCU to fail to start.
