43.4 CPU Idle Power

Table 43-7. CPU Idle Current Consumption Electrical Specifications
DC CHARACTERISTICS Standard Operating Conditions: VDD and VDDIO 2.7V to 5.5V (unless otherwise stated)

Operating temperature: -40°C ≤ TA ≤ +85°C for Industrial
Param. No. Symbol Characteristics Clock/Freq Typ.(1) Max. Units Conditions
IPWR_1 IDD_IDLE CPU IDD in IDLE mode FDPLL 48MHz 19.1 25 µA/MHz VDDANA = VDDIO = 5V

XOSC32K at 32.768 kHz as reference of FDPLL(2)
IPWR_3 19 24.8 µA/MHz VDDANA = VDDIO = 3.3V

XOSC32K at 32.768 kHz as reference of FDPLL(2)
IPWR_5 OSC48M 48MHz 17.3 22.2 µA/MHz VDDANA = VDDIO = 5V

XOSC32K Off(2)
IPWR_7 17.2 22 µA/MHz VDDANA = VDDIO = 3.3V

XOSC32K Off(2)
Note:
  1. Typical values at 25°C only.
  2. Conditions:
    • No peripheral modules are operating (That is, all peripherals inactive)
    • All clock sources disabled unless otherwise specified. (that is, XOSC32 = 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 stopped and AHB clocks undivided
    • All I/O pins configured as input pins pulled down or tied to GND
    • WDT, RTC, CFD Clock Fail Detect disabled
    • RESET = VDDIO
    • NVMCTRL cache enabled
    • BODVDD disabled
    Note: µa/MHz varies over temperature. Worst case is given by max.
