26.9

CPU running at full speed (32MHz), 32MHz XOSC

running, radio in TX mode, 0dBm output power. No

peripherals active. Low CPU activity.

Power mode 1

190

µA

Digital regulator on, 16 MHz RCOSC and 32 MHz crystal

oscillator off. 32.768 kHz XOSC, POR and ST active.

RAM retention.

Power mode 2

0.5

µA

Digital regulator off, 16 MHz RCOSC and 32 MHz crystal

oscillator off. 32.768 kHz XOSC, POR and ST active.

RAM retention.

Power mode 3

0.3

µA

No clocks. RAM retention. POR active.

Peripheral Current

Consumption

Adds to the figures above if the peripheral unit is

activated

Sleep Timer

0.2

µA

Including 32.753 kHz RCOSC.

ADC

1.2

When converting.

Flash write

Estimated value

Flash erase

Estimated value

1 Normal Flash access means that the code used exceeds the cache storage so cache misses will

happen frequently.
