Shading of rows is to assist in readability of the table.

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 V

DD

 or V

SS

, and all features that add delta 

current disabled (such as WDT, Timer1 Oscillator, BOR, etc.).

The supply current is mainly a function of operating voltage, frequency and mode. Other factors, such as I/O pin loading 
and switching rate, oscillator type and circuit, internal code execution pattern and temperature, also have an impact on 
the current consumption.
The test conditions for all I

DD

 measurements in active operation mode are: 

OSC1 = external square wave, from rail-to-rail; all I/O pins tri-stated, pulled to V

DD

;

MCLR = V

DD

; WDT enabled/disabled as specified. 

For RC oscillator configurations, current through R

EXT

 is not included. The current through the resistor can be estimated 

by the formula: Ir = V

Standard, low-cost 32 kHz crystals have an operating temperature range of -10°C to +70°C. Extended temperature 
crystals are available at a much higher cost.
