Peripheral Power Consumption
The values in Table 8-5 are measured values of power consumption under the following
conditions.
• Operating conditions external core supply (Figure 8-1)
– V_VDDIN = 3.3V
– V_VDDCORE = 1.8V, supplied by the internal regulator
– Corresponds to the 3.3V + 1.8V dual supply mode , please refer to the Supply and
Startup Considerations section for more details
• TA = 25°C
• Oscillators
– OSC0 on external clock running
– PLL running at 48MHz with OSC0 as reference
• Clocks
– OSC0 external clock used as main clock source
– CPU, HSB, and PB clocks undivided
