Power Supplies
Power Consumption
AT91CAP7E
The AT91CAP7E has several types of power supply pins:
Note:
The AT91CAP7E consumes about 600 μA of static current on VDDCORE at typical conditions
(1.2V, 25°C).
On VDDBU, the current does not exceed 30 μA at typical conditions.
For dynamic power consumption, the AT91CAP7E consumes about 0.33 mW/MHz of power or
275 μA/MHz of current on VDDCORE at typical conditions (1.2V, 25°C) and with the ARM sub-
system running full-performance algorithm with on-chip memories, and no peripherals active.
