38.3
Power Consumption
 Typical power consumption of PLLs, Slow Clock and Main Oscillator.
 Power consumption of power supply in two different modes: Active and ultra Low-power.
 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:
 V_DDIO = V_DDIN = V_DDFLASH= 3.3V
 V_DDCORE = V_DDPLL = 1.85V
 TA = 25°C
 There is no consumption on the I/Os of the device
