Power Consumption

The values are measured power consumption under the following conditions, except where otherwise noted:

V_DD = 3V
T = 25°C
OSC20M used as the system clock source, except where otherwise specified
System power consumption measured with peripherals disabled and without I/O drive

Table 1. Power Consumption in Active and Idle Mode
Mode	Description	Condition		Typ.	Max.	Unit
Active	Active power consumption	CLK_CPU = 20 MHz (OSC20M)	V_DD = 5V	9.0	-	mA
		CLK_CPU = 10 MHz (OSC20M div2)	V_DD = 5V	4.8	-	mA
		CLK_CPU = 10 MHz (OSC20M div2)	V_DD = 3V	2.7	-	mA
		CLK_CPU = 5 MHz (OSC20M div4)	V_DD = 5V	2.8	-	mA
			V_DD = 3V	1.6	-	mA
			V_DD = 2V	1.0	-	mA
		CLK_CPU = 32.768 kHz (OSCULP32K)	V_DD = 5V	18	-	µA
			V_DD = 3V	10	-	µA
			V_DD = 2V	7	-	µA
Idle	Idle power consumption	CLK_CPU = 20 MHz (OSC20M)	V_DD = 5V	2.8	6.3⁽¹⁾	mA
		CLK_CPU = 10 MHz (OSC20M div2)	V_DD = 5V	1.7	3.1⁽¹⁾	mA
		CLK_CPU = 10 MHz (OSC20M div2)	V_DD = 3V	0.9	1.9⁽¹⁾	mA
		CLK_CPU = 5 MHz (OSC20M div4)	V_DD = 5V	1.2	2.0⁽¹⁾	mA
			V_DD = 3V	0.6	1.2	mA
			V_DD = 2V	0.4	-	mA
		CLK_CPU = 32.768 kHz (OSCULP32K)	V_DD = 5V	8.0	20⁽¹⁾	µA
			V_DD = 3V	4.0	15⁽¹⁾	µA
			V_DD = 2V	1.7	-	µA

Table 2. Power Consumption in Power-Down, Standby and Reset Mode
Mode	Description	Condition		Typ. 25°C	Max. 25°C	Max. 85°C⁽¹⁾	Max. 125°C	Unit
Standby	Standby power consumption	RTC running at 1.024 kHz from internal OSCULP32K	V_DD = 3V	0.7	3.0	6.0	8.0	µA
Power Down/Standby	Power down/Standby power consumption are the same when all peripherals are stopped	All peripherals stopped	V_DD = 3V	0.1	2.0	5.0	7.0	µA
Reset	Reset power consumption	Reset line pulled down	V_DD = 3V	100	-	-	-	µA
