* 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.
Note 1:
This is the limit to which V
DD
can be lowered 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 tristated, 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
and V
SS
.
4:
For RC osc mode, current through Rext is not included. The current through the resistor can be estimated by
the formula Ir = V
DD
/2Rext (mA) with Rext in kOhm.
5:
Timer1 oscillator (when enabled) adds approximately 20
A to the specification. This value is from charac-
terization and is for design guidance only. This is not tested.
6:
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.
7:
This is the voltage where the device enters the Brown-out Reset. When BOR is enabled, the device will
perform a brown-out reset when V
DD
falls below V
BOR
.
