Note

The test conditions for all IDD measurements in active operation mode are: OSC1 = external square wave, from

rail-to-rail; all I/O pins tri-stated, pulled to VDD; MCLR = VDD; WDT disabled.

The supply current is mainly a function of the operating voltage and frequency. Other factors, such as I/O pin loading

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

consumption.

For RC oscillator configurations, current through REXT is not included. The current through the resistor can be extended

by the formula IR = VDD/2REXT (mA) with REXT in k



FVR and BOR are disabled.
