42023ES–SAM–07/2013

The values in 

Table 34-7

 are measured values of power consumption under the following condi-

tions, except where noted:

• Operating conditions for power scaling mode 1

– V

VDDIN

 = 3.3V

• Wake up time from low power modes is measured from the edge of the wakeup signal to the 

first instruction fetched in flash.

• Oscillators

– OSC0 (crystal oscillator) and OSC32K (32kHz crystal oscillator) stopped

– RCFAST Running at 12MHz 

• Clocks

– RCFAST used as main clock source

– CPU, AHB clocks undivided

– APBC and APBD clocks divided by 4

– APBA and APBB bridges off

– The following peripheral clocks running

• PM, SCIF, AST, FLASHCALW, APBC and APBD bridges
