† Data in "Typ" column is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance
only and are not tested.
NR Not rated for operation.
Note 1: This is the limit to which V
DD 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 I
DD measurements in active operation mode are:
OSC1 = external square wave, from rail-to-rail; all I/O pins tri-stated, pulled to V
DD,
T0CKI = V
DD, 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 V
DD and VSS.
4: For RC osc configuration, current through R
EXT is not included. The current through the resistor can be
estimated by the formula I
R = 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 I
DD measurement.
