32.5 Power Consumption

The values are measured power consumption under the following conditions, except where noted:
  • VDD = 3V
  • TA = 25°C
  • OSC20M used as the system clock source, except where otherwise specified
  • System power consumption measured with peripherals disabled and I/O ports driven low with inputs disabled
