2: The supply current is mainly a function of the operating voltage and frequency. Other factors such as I/O pin
3: The power-down current in SLEEP mode does not depend on the oscillator type. Power-down current is

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.
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
OSC1 = external square wave, from rail to rail; all I/O pins tristated, pulled to V
MCLR = V
Current consumed from the oscillator and I/O’s driving external capacitive or resistive loads need to be con-
sidered.
For the RC oscillator, the current through the external pull-up resistor (R) can be estimated as: V
For capacitive loads, The current can be estimated (for an individual I/O pin) as (C
C
The capacitive currents are most significant when the device is configured for external execution (includes
extended microcontroller mode).
