44.6 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 1 wait states for VDD=3.3V and 3 wait states for VDD=1.8V
    • Low power cache is enabled.
    • BOD33 disabled
    • I/Os are inactive input mode with Input trigger disable
  • Oscillators
    • XOSC (crystal oscillator) stopped
    • XOSC32K (32kHz crystal oscillator) running with external 32kHz crystal
    • When in active PL2 mode FDPLL using XOSC32K as reference and running at 32MHz
    • When in active PL0 internal Multi RC Oscillator running at 8MHz or 4MHz
