Param. No. Symbol Characteristics Clock/Freq Typ. Max. Units Conditions
APWR_1 IDD_ACTIVE MCU IDD in active mode FDPLL 48MHz 169.5 184.9 µA/MHz AVDD = VDDIO = 5V

XOSC32K @ 32.768 kHz as reference of FDPLL

APWR_3 167.8 182.6 µA/MHz AVDD = VDDIO = 3.3V

XOSC32K @ 32.768 kHz as reference of FDPLL

APWR_5 OSC48M 48MHz 165 181.5 µA/MHz AVDD = VDDIO = 5V

XOSC32K Off

APWR_7 163.1 179.9 µA/MHz AVDD = VDDIO = 3.3V

XOSC32K Off

Note:
  1. Conditions:
    • No peripheral modules are operating (i.e., all peripherals inactive)
    • All clock generation sources disabled unless otherwise specified. (i.e. XOSC32K=Off)
    • GCLK clock generators 1 to 8 stopped (GENCTRL[8:1].GENEN=0)
    • AHB/APB clocks not needed are masked: AHBMASK=0x70, APB(A/B/C/D)MASK=0x0
    • CPU and AHB clocks undivided
    • I/Os are inactive input mode with input trigger disabled
    • WDT, RTC, CFD Clock Fail Detect disabled
    • RESET = VDDIO
    • MCU is running on Flash with two Wait States
    • NVMCTRL cache enabled
    • BODVDD disabled
    • Note: µA/MHz varies over temperature. Worst case is given by max.
  2. CPU Running CoreMark® Test Suite.
