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 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 or VSS, T0CKI = VDD,
MCLR
= VDD; WDT disabled.
Current consumed from the oscillator and I/O’s driving external capacitive or resistive loads needs to be
considered.
For the RC oscillator, the current through the external pull-up resistor (R) can be estimated as:
V
DD/(2  R).
For capacitive loads, the current can be estimated (for an individual I/O pin) as (C
LVDD)  f
C
L = Total capacitive load on the I/O pin; f = average frequency the I/O pin switches.
The capacitive currents are most significant when the device is configured for external execution (includes
Extended Microcontroller mode).
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 or VSS.
4: For RC osc configuration, current through R
EXT is not included. The current through the resistor can be esti-
mated by the formula I
R = VDD/2REXT (mA) with REXT in kOhm.
5: This is the voltage where the device enters the Brown-out Reset. When BOR is enabled, the device (-16)
will operate correctly to this trip point.
