These parameters are characterized but not tested.
Data in “Typ” column is at 5.0V, 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 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 con-
sumption.
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.
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
or V
SS
.
4:
The
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.
5:
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 k
.
