Power Consumption
Power Consumption Versus Modes
The values in
sumption with operating conditions as follows:
Figure 40-1. Measure Schematics:
• 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
• V
• V
• T
• There is no consumption on the I/Os of the device
having enabled then disabled the corresponding clock.
