Param. No. Symbol Characteristics Clock/Freq Typ.(1) Max. Units Conditions
APWR_1 IDD_ACTIVE(2,3) MCU IDD in Active mode w/LDO mode selected PLL 64 MHz 105 411 μA/MHz VDD = VDDANA = 3.3V
PLL 48 MHz 89 395 μA/MHz VDD = VDDANA = 3.3V
APWR_13 MCU IDD in Active mode w/BUCK mode selected PLL 64 MHz 70 291 μA/MHz VDD = VDDANA = 3.3V
PLL 48 MHz 62 279 μA/MHz VDD = VDDANA = 1.8V
Note:
  1. Typical value measured during characterization across voltage and temperature.
  2. The test conditions are as follows:
    • All GPIO are input and pulled up.
    • RF System ON with default settings.
    • All Peripherals disabled with PMD bits.
    • All PB clocks are divided by 16.
    • LPRC is set as LPCLK.
    • SOSC is disabled.
    • PMU 1 MHz clock is derived from FRC. FRC is divided by 8.
    • Cache is enabled and configured wait time as 0xF.
    • WCM memories configured in Retention + NAP mode.
    • DSU is disconnected.

  3. MCU running while(1) loop with 50 NOP instructions.

  4. These parameters are characterized but not tested in manufacturing.
