Legend: Rows are shaded for improved readability.
Note 1: This is the limit to which V
DD can be lowered in Sleep mode, or during a device Reset, 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
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 high-impedance state and tied to V
DD and VSS
and all features that add delta current disabled (such as WDT, Timer1 Oscillator, BOR, ...).
4: For RC oscillator configuration, current through R
EXT is not included. The current through the resistor can
be estimated by the formula Ir = V
DD/2 REXT (mA) with REXT in kOhm.
5: The LVD and BOR modules share a large portion of circuitry. The ΔI
BOR and ΔILVD currents are not
additive. Once one of these modules is enabled, the other may also be enabled without further penalty.
