Design Notes
The TMS320F28034PNT requires a 3.3V I/O supply and a 1.8V core supply. The core supply can be generated internally using the on-chip voltage regulator, but external capacitors are required as specified in the datasheet. Ensure proper decoupling with 100nF and 10uF capacitors close to the VDD and VDDIO pins to minimize noise and voltage transients.
For the LQFP-80 package, ensure adequate thermal relief and grounding. The exposed pad (if present) should be soldered to a large copper area for heat dissipation. Route JTAG signals with controlled impedance and keep them short to avoid signal integrity issues. Place the crystal oscillator close to the X1/X2 pins with proper load capacitors.
A common mistake is neglecting the internal voltage regulator's capacitor requirements, leading to unstable core voltage. Also, ensure the ADC reference pins (VREFHI/VREFLO) are properly bypassed with capacitors to achieve accurate conversions. Avoid exceeding the absolute maximum ratings on any pin, especially during programming.
