Power Consumption

The values in this section are measured values of power consumption under the following conditions, except where noted:

Operating Conditions
- V_DDIO = 3.3V or 1.8V
- CPU is running on Flash with required Wait states, as recommended in the NVM Characteristics section.
- Low power cache is enabled
- BOD33 is disabled
- I/Os are configured with digital input trigger disabled (default Reset configuration)
Oscillators
- XOSC (crystal oscillator) stopped
- XOSC32K (32.768 kHz crystal oscillator) running with external 32.768 kHz crystal
- When in active PL2 mode on FDPLL96M at 32 MHZ, DPLL is using XOSC32K as reference clock and running at 32 MHz
- When in Active mode on DFLLULP, the DFLLULP is configured in Closed Loop mode using XOSC32K as reference clock and MCLK.CTRLA.CKSEL = 1
