54.7 Power Consumption
The values in this section are measured values of power
consumption under the following conditions, except where noted:
- Operating
Conditions
- CPU is running on Flash with automatic wait state
- Low-power cache enabled.
- BOD33 is disabled
- I/Os are inactive input mode with input trigger disabled
- Oscillators
- XOSC0 (crystal oscillator) running with external 32 MHz crystal
- XOSC32K (32 kHz crystal oscillator) running with external 32 kHz crystal in LP mode
- FDPLL is using XOSC32K as reference
- DFLL is using XOSC32K as reference
