46.3 Power Consumption
• Typical power consumption of PLLs, Slow Clock and Main Oscillator.
• Power consumption of power supply in four different modes: Active, Idle, Ultra Low-power
and Backup.
• 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 1094 are estimated values of the power con-
sumption with operating conditions as follows:
• V
DDIOM
= 1.8V
• V
DDIOP0 and 1
= 3.3V
• V
DDPLLA
= 1.0V
• V
DDCORE
= 1.0V
• V
