* These parameters are characterized but not tested.
† Data in "Typ" column is at 5V, 25˚C unless otherwise stated. These parameters are for design guidance
only and are not tested.
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 tristated, pulled to 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 Rext is not included. The current through the resistor can be esti-
mated by the formula Ir = V
DD/2Rext (mA) with Rext in kOhm.
5: Timer1 oscillator (when enabled) adds approximately 20 µA to the specification. This value is from charac-
terization and is for design guidance only. This is not tested.
6: The ∆ current is the additional current consumed when this peripheral is enabled. This current should be
added to the base I
DD or IPD measurement.
