46.6 Power Consumption

The values in this section are measured values of power consumption under the following conditions, except where noted:
  • Operating Conditions
    • VVDDIN = 3.3V or 1.8V
    • For VDDIN = 1.8V, CPU is running on Flash with 3 wait states
    • For VDDIN = 3.3V, CPU is running on Flash with 1 wait state in PL0 and 2 wait states in PL2.
    • Low-power cache is enabled
    • BOD33 is disabled
  • Oscillators
    • XOSC (crystal oscillator) stopped
    • XOSC32K (32 kHz crystal oscillator) running with external 32 kHz crystal
    • When in active Performance Level 2 (PL2) mode, DFLL48M is running at 48 MHz and using XOSC32K as reference
    • When in active PL0 mode, the internal Multi RC Oscillator is running at specified frequency
  • Clocks
    • DFLL48M used as main clock source when in PL2 mode. In PL0 mode, OSC16M used at 4, 8, or 12 MHz
    • Clock masks and dividers at reset values: All AHB and APB clocks enabled, CPUDIV = 1, BUPDIV = 8, LPDIV = 1
    • I/Os are configured in Digital Functionality Disabled mode
