These parameters are characterized but not tested.

Data in "Typ" column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only and are not

tested.

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

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 con-

sumption.

The test conditions for all IDD measurements in active operation mode are:

OSC1 = external square wave, from rail to rail; all I/O pins tristated, pulled to VDD

MCLR = VDD; WDT enabled/disabled as specified.

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 hi-impedance state and tied to VDD or VSS.

For ER osc configuration, current through Rext is not included. The current through the resistor can be estimated by the

formula Ir = VDD/2Rext (mA) with Rext in kOhm.

The ∆ current is the additional current consumed when the peripheral is enabled. This current should be added to the base

(IPD or IDD) current.
