11 Power Supply Recommendations

The power supply must provide a constant voltage with a 10% maximum variation of the nominal value and has to be able to provide at least the maximum current consumption of the device for the selected nominal voltage only for the UART device:

  • VCC = 1.8 V
  • VCC = 2.5 V
  • VCC = 3.3 V
  • VCC = 5 V

The VCC pin must have a 1-µF bypass capacitor placed as close as possible to this pin. Also, TI recommends to include two extra capacitors in parallel, which should also be placed as close as possible to the VCC pin. The suggested values for these extra capacitors are 0.1 µF and 0.01 µF, respectively.

Place as close as possible to the VCC pin of the UART.
