Note 1:

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 or VSS 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 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.

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

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

Ω.

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.

BOR and HLVD enable internal band gap reference. With both modules enabled, current consumption will be

less than the sum of both specifications.
