37.4 Power Consumption
The values are measured power consumption under the following
conditions, except where noted:
- VDD = 3V
- T = 25°C
- OSC20M (16 MHz setting) used as the system clock source, except where otherwise specified
- System power consumption measured with peripherals disabled and without I/O drive

---|---|---|---|---|---|---|
Active | Active power consumption | CLK_CPU = 16 MHz | VDD = 5V | 8 | - | mA |
CLK_CPU = 8 MHz (div2) | VDD = 5V | 4.2 | - | mA | ||
