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 599 are measured values of the power con-
sumption with operating conditions as follows:
•V
DDIO
= V
DDIN
= V
DDFLASH
= 3.3V
•V
DDCORE
= V
DDPLL
= 1.85V
•T
A = 25°C
• There is no consumption on the I/Os of the device
