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.

Note1:

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

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 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 high-impedance state and tied to VDD and VSS.

For RC Osc mode, 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.

Timer1 oscillator (when enabled) adds approximately 20

A to the specification. This value is from characterization and is

for design guidance only. This is not tested.

The

 current is the additional current consumed when this peripheral is enabled. This current should be added to the base

IDD or IPD measurement.

This is the voltage where the device enters the Brown-out Reset. When BOR is enabled, the device will operate correctly to

this trip point.
