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.
40.3.1 Power Consumption versus Modes
The values in Table 40-3 and Table 40-4 on page 711 are estimated values of the power consumption with operat-
ing conditions as follows:
• V_DDIOM = V_DDIOP = 3.3V
• V_DDPLL = 1.8V
• V_DDCORE = V_DDBU = 1.8V
• TA = 25° C
• There is no consumption on the I/Os of the device
