46.3 Power Consumption
z Typical power consumption of PLLs, Slow Clock and Main Oscillator.
z Power consumption of power supply in four different modes: Active, Idle, Ultra Low-power and Backup.
z Power consumption by peripheral: calculated as the difference in current measurement after having enabled then
disabled the corresponding clock.
46.3.1 Power Consumption versus Modes
The values in Table 46-3 and Table 46-4 on page 1044 are estimated values of the power consumption with operating
conditions as follows:
z V
DDIOM
= 1.8V
z V
DDIOP0 and 1
= 3.3V
z V
DDPLLA
= 1.0V
z V
DDCORE
= 1.0V
z V
DDBU
= 3.3V
z TA = 25° C
z There is no consumption on the I/Os of the device
Figure 46-1. Measures Schematics
These figures represent the power consumption estimated on the power supplies.
