Note 1: This is the limit to which VDD can be lowered in SLEEP mode, or during a device RESET, without losing RAM data.

2: 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.

3: 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, and all

features that add delta current disabled (such as WDT, Timer1 Oscillator, BOR, etc.).

4: The LVD and BOR modules share a large portion of circuitry. The

IBOR and ILVD currents are not additive.

Once one of these modules is enabled, the other may also be enabled without further penalty.
