Shading of rows is to assist in readability of of the table.
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.
This is the limit to which V
DD
can be lowered without losing RAM data.
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 = V
DD
; WDT enabled/disabled as specified.
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-impendance state and tied to V
DD
and V
SS
.
For RC osc configuration, current through R
EXT
is not included. The current through the resistor can be
estimated by the formula Ir = V
DD
/2R
EXT
(mA) with R
EXT
in kOhm.
Timer1 oscillator (when enabled) adds approximately 20
μ
A to the specification. This value is from
characterization and is for design guidance only. This is not tested.
The
Δ
current is the additional current consumed when this peripheral is enabled. This current should be
added to the base I
DD
or I
PD
measurement.
When BOR is enabled, the device will operate correctly until the V
BOR
voltage trip point is reached.
