DC CHARACTERISTICS				Standard Operating Conditions: VDD and VDDIO 2.7V to 5.5V (unless otherwise stated) Operating temperature: -40°C ≤ T_A ≤ +85°C for Industrial
Param. No.	Symbol	Characteristics	Clock/Freq	Typ.	Max.	Units	Conditions
IPWR_1	IDD_IDLE0	MCU IDD in IDLE0 mode	FDPLL 48 MHz	62.4	74.2	µA/MHz	AVDD = VDDIO = 5V XOSC32K @ 32.768 kHz as reference of FDPLL
IPWR_3			FDPLL 48 MHz	62.1	73.9	µA/MHz	AVDD = VDDIO = 3.3V XOSC32K @ 32.768 kHz as reference of FDPLL
IPWR_5			OSC48M 48 MHz	58.7	70.3	µA/MHz	AVDD = VDDIO = 5V XOSC32K Off
IPWR_7			OSC48M 48 MHz	58.4	70.1	µA/MHz	AVDD = VDDIO = 3.3V XOSC32K Off
IPWR_13	IDD_IDLE2	MCU IDD in IDLE2 mode	FDPLL 48 MHz	28.4	40.9	µA/MHz	AVDD = VDDIO = 5V XOSC32K @ 32.768 kHz as reference of FDPLL
IPWR_15			FDPLL 48 MHz	28.3	40.7	µA/MHz	AVDD = VDDIO = 3.3V XOSC32K @ 32.768 kHz as reference of FDPLL
IPWR_17			OSC48M 48 MHz	25	36.9	µA/MHz	AVDD = VDDIO = 5V XOSC32K Off
IPWR_19			OSC48M 48 MHz	24.9	36.8	µA/MHz	AVDD = VDDIO = 3.3V XOSC32K Off

Note: µA/MHz varies over temperature. Worst case is given by maximum.

Note:

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
- MCU 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
- NVMCTRL cache enabled
- BODVDD disabled
