38.3
Power Consumption
ï¬ Typical power consumption of PLLs, Slow Clock and Main Oscillator.
ï¬ Power consumption of power supply in two different modes: Active and ultra Low-power.
ï¬ Power consumption by peripheral: calculated as the difference in current measurement after having enabled then
disabled the corresponding clock.
38.3.1 Power Consumption Versus Modes
The values in Table 38-6 and Table 38-7 on page 585 are measured values of the power consumption with operating
conditions as follows:
ï¬ VDDIO = VDDIN = VDDFLASH= 3.3V
ï¬ VDDCORE = VDDPLL = 1.85V
ï¬ TA = 25°C
ï¬ There is no consumption on the I/Os of the device
