These parameters are characterized but not tested.

†

Data in "Typ" column is at 5.0V, 25

°C unless otherwise stated. These parameters are for design guidance only

and are not tested.

Note 1: This is the limit to which VDD 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 IDD measurements in active operation mode are:

OSC1=external square wave, from rail to rail; all I/O pins tristated, pulled to VDD, T0CKI = 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 and VSS.

4: For RC 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.

5: The

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

added to the base IDD measurement.
