15.7 Power Consumption

The values in this section are measured values of power consumption under the following conditions, except where noted:
  • Operating Conditions
    • VDDIN = 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
    • AT86RF212B is in sleep mode
  • Oscillators
    • XOSC (crystal oscillator) stopped
    • XOSC32K (32KHz crystal oscillator) running with external 32KHz crystal
    • When in active Performance Level 2 (PL2) mode, DFLL48M is running at 48MHz 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 12MHz
    • Clock masks and dividers at reset values: All AHB & APB clocks enabled, CPUDIV=1, BUPDIV=1, LPDIV=1
    • I/Os are configured in Digital Functionality Disabled mode
