Design Notes
The TMS320F28377SZWTT requires separate 1.2V core and 3.3V I/O supplies. Use low-ESR ceramic capacitors (100nF and 10uF) close to each power pin. For the core supply, a dedicated LDO or DC-DC converter with adequate current capability is recommended. Ensure proper decoupling to prevent noise-induced errors in ADC and high-speed interfaces.
Follow the layout guidelines in the TI datasheet for the 337-pin NFBGA package. Route high-speed signals (e.g., EMIF, ADC inputs) with controlled impedance and minimize trace lengths. Place the crystal oscillator close to the X1/X2 pins and keep the ground plane continuous under the device. Use vias for thermal relief to the exposed pad.
Avoid exceeding the absolute maximum ratings for supply voltages. Ensure the boot mode pins are configured correctly for the desired boot source. For functional safety applications, implement the recommended self-test routines and use the ECC features on flash. Verify the ADC reference voltage and input scaling to avoid measurement errors.
