Note 1:

The peripheral current is the sum of the base IDD or IPD and the additional current consumed when this peripheral is

enabled. The peripheral

 current can be determined by subtracting the base IDD or IPD current from this limit. Max

values should be used when calculating total current consumption.

The power-down current in Sleep mode does not depend on the oscillator type. Power-down current is measured with

the part in Sleep mode, with all I/O pins in high-impedance state and tied to VDD.

A/D oscillator source is FRC.
