* These parameters are characterized but not tested.

鈥?Data in 鈥淭yp鈥?column is at 5.0V, 25掳C, unless otherwise stated. These parameters are for design guidance only

and are not tested.

Note 1: This is the limit to which V

can be lowered in SLEEP mode 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 I

measurements in active operation mode are:

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

MCLR = V

; WDT enabled/disabled as speci铿乪d.

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 V

or V

4: For RC osc con铿乬uration, current through Rext is not included. The current through the resistor can be

estimated by the formula Ir = V

/2Rext (mA) with Rext in k鈩?

5: The

鈭?/div>

current is the additional current consumed when this peripheral is enabled. This current should be

added to the base I

or I

measurement.
