The values are measured power consumption under the following
conditions, except where otherwise specified:
- T = 25°C
- OSC20M at 16 MHz used as system clock
source
- No peripherals enabled and all I/O ports
set to inputs connected to VDD or GND

| Active | Active power consumption | CLK_CPU=16 MHz | VDD=5V | 7.9 | 10 | mA |
| CLK_CPU=8 MHz (div2) | VDD=5V | 4.0 | 5.5 | mA |
| VDD=3V | 2.2 | 3.5 | mA |
| CLK_CPU=32 KHz (OSCULP32K) | VDD=5V | 19 | 35 | µA |
| VDD=3V | 11 | 25 | µA |
| Idle | Idle power consumption | CLK_CPU=16 MHz | VDD=5V | 3.4 | 5 | mA |
| CLK_CPU=8 MHz (div2) | VDD=5V | 1.7 | 2.5 | mA |
| VDD=3V | 0.9 | 1.5 | mA |
| CLK_CPU=32 KHz (OSCULP32K) | VDD=5V | 8.0 | 20 | µA |

Table 35-5. Power Consumption in Power-Down,
Standby, and Reset Mode| Mode | Description | Condition | Typ. 25°C | Max. 85°C | Max. 125°C | Unit |
|---|
| Standby | Standby power consumption | RTC running at 1.024 kHz from external XOSC32K (CL=7.5 pF) | VDD=3V | 0.69 | - | - | µA |
| RTC running at 1.024 kHz from internal OSCULP32K | VDD=3V | 0.71 | 6.0 | 8.0 | µA |
| Power Down/Standby | Power down/Standby power consumption are the same when all
peripherals are stopped | All peripherals stopped | VDD=3V | 0.1 | 5.0 | 7.0 | µA |
| Reset | Reset power consumption | Reset line pulled down | VDD=3V | 100 | - | - | µA |
