* These parameters are characterized but not tested.

Note 1:

Data in the Typical (“Typ”) column is based on characterization results at 25

°C. This data is for design

guidance only and is not tested.

This is the limit to which VDD can be lowered in Sleep mode without losing RAM data.

The supply current is mainly a function of the operating voltage and frequency. Other factors such as bus

loading, oscillator type, bus rate, internal code execution pattern and temperature also have an impact on

the current consumption.

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 VSS, T0CKI = VDD, MCLR =

VDD; WDT enabled/disabled as specified.

For standby current measurements, the conditions are the same as IDD, except that the device is in Sleep

mode. If a module current is listed, the current is for that specific module enabled and the device in Sleep.
