Wake-Up Time

Conditions:

VDDIO/VDDANA = 3.3V
LDO Regulation mode
CPU clock = OSC16M @ 4 MHz
One Wait-state
Cache enabled
Flash Fast Wake-up enabled (NVMCTRL.CTRLB.FWUP = 1)
Flash in WAKEUPINSTANT mode (NVMCTRL.CTRLB.SLEEPPRM = 1)

Measurement Method:

For Idle and Standby, the CPU sets an I/O by writing PORT->IOBUS without jumping in an interrupt handler (Cortex M23 register PRIMASK = 1). The wake-up time is measured between the edge of the wake-up input signal and the edge of the GPIO pin.

For Off mode, the exit of the mode is done through the reset pin, the time is measured between the falling edge of the RESETN signal (with the minimum reset pulse length), and the set of the I/O which is done by the first executed instructions after Reset.

Sleep Mode	Condition		Typ	Unit
Idle	PL2 or PL0		1.5	μs
Standby	PL0	PDSW domain in retention	5.3
	PL0	PDSW domain in active	2.6
	PL2 Voltage scaling at default values: SUPC >VREG.VSVSTEP=0 SUPC > VREG.VSPER=0	PDSW domain in retention	76
		PDSW domain in active	75
	PL2 Voltage scaling at fastest setting: SUPC > VREG.VSVSTEP=15 SUPC > VREG.VSPER=0	PDSW domain in retention	16
		PDSW domain in active	15
OFF	L10 with BOOTOPT=0		3.2	ms
	L11 with BOOTOPT=0		4.1
	L10 or L11 with BOOTOPT=1, BS = 0x40		210
	L10 or L11 with BOOTOPT=1, BS = 0x80		410
	L10 or L11 with BOOTOPT=2, BS = 0x40		210
	L10 or L11 with BOOTOPT=2, BS = 0x80		410
