48.3

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

48.3.1 Power Consumption versus Modes

The values in Table 48-3 and Table 48-4 on page 1216 are estimated values of the power consumption with

operating conditions as follows:

 VDDIOM0 = 1.8V

 VDDIOP0 and 1 = 3.3V

 VDDPLLA = 1.0V

 VDDCORE = 1.0V

 VDDBU = 3.3V

 TA = 25°C

 There is no consumption on the I/Os of the device.
