55.2 Power Consumption (105°C)

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 on LDO and external clock 32768 on Buck mode
    • DFLL48M is using XOSC32K as reference
