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			FDPLL 48MHz	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			OSC48M 48MHz	17.2	22	µA/MHz	VDDANA = VDDIO = 3.3V XOSC32K Off⁽²⁾
Note: Typical values at 25°C only. 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.
