†

"Typ" column data is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are

not tested.

Note 1: The supply current is mainly a function of the operating voltage and frequency. Other factors such as I/O pin load-

ing and switching rate, oscillator type, internal code execution pattern, and temperature also have an impact on the

current consumption.

2: Should operate down to VBOR but not tested below 2.0V.

3: The test conditions for all IDD measurements in active Operation mode are: all I/O pins tristated, pulled to VDD.

MCLR = VDD; WDT enabled/disabled as specified. The power-down/shutdown current in SLEEP mode does not

depend on the oscillator frequency. Power-down current is measured with the part in SLEEP mode, with all I/O pins

in hi-impedance state and tied to VDD or VSS. The

 current is the additional current consumed when the WDT is

enabled. This current should be added to the base IDD or IPD measurement.
