47.3 Power Consumption

The values in this section are measured values of power consumption under the following conditions, except where noted:
  • Operating Conditions
    • VDDIO = 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
