41.6 Power Consumption
The values in this section are measured values of power consumption under the following conditions, except where noted:
- Operating conditions
- VVDDIN = 3.3 V
- VVDDIN = 2.7V, CPU is running on Flash with 1 wait state
- Wake up time from sleep mode is measured from the edge of the wakeup signal to the execution of the first instruction fetched in flash.
- Oscillators
- XOSC (crystal oscillator) stopped
- XOSC32K (32 kHz crystal oscillator) running with external 32kHz crystal
- DFLL48M using XOSC32K as reference and running at 48 MHz
- Clocks
- DFLL48M used as main clock source, except otherwise specified
- CPU, AHB clocks undivided
- APBA clock divided by 4
- APBB and APBC bridges off
- The following AHB module clocks are running: NVMCTRL, APBA bridge
- All other AHB clocks stopped
- The following peripheral clocks running: PM, SYSCTRL, RTC
- All other peripheral clocks stopped
- I/Os are inactive with internal pull-up
- CPU is running on flash with 1 wait states
- Cache enabled
- BOD33 disabled
