37.4 Power Consumption

The values are measured power consumption under the following conditions, except where noted:
  • VDD=3V
  • T=25°C
  • OSC20M used as system clock source, except where otherwise specified
  • System power consumption measured with peripherals disabled and without I/O drive.
