Conditions

Legend: Rows with standard voltage device data only are shaded for improved readability.

†

Data in "Typ" column is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance

only and are not tested.

Not rated for operation.

Note 1: This is the limit to which VDD can be lowered 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,

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.
