Note: µA/MHz varies over temperature. Worst case is given by maximum.
Note:
  1. Conditions:
    • No peripheral modules are operating (i.e., all peripherals are 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
    • Disabled WDT (Watchdog Timer), RTC (Real-Time Clock), and CFD (Clock Failure Detection)
    • RESET = VDDIO
    • MCU is running on Flash with two Wait States
    • NVMCTRL cache enabled
    • BODVDD disabled
  2. CPU Running CoreMark® Test Suite.

Operation Conditions:

  • VDD = VDDIO = 3.3 / 5.0V
  • Refer to Notes 1 and 2 mentioned earlier in the table MCU Active Current Consumption Electrical Specifications.
