Note
1:
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 a high-impedance state and tied to V
DD
 or V
SS
, and all features that add delta 
current are disabled (such as WDT, SOSC oscillator, BOR, etc.).
2:
The supply current is mainly a function of operating voltage, frequency and mode. Other factors, such as I/O pin loading 
and switching rate, oscillator type and circuit, 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. 
3:
Standard, low-cost 32 kHz crystals have an operating temperature range of -10°C to +70°C. Extended temperature 
crystals are available at a much higher cost.
4:
Voltage regulator disabled (ENVREG = 0, tied to V
SS
, RETEN (CONFIG1L<0>) = 1).
5:
Voltage regulator enabled (ENVREG = 1, tied to V
DD
, SRETEN (WDTCON<4>) = 1 and RETEN (CONFIG1L<0>) = 0).
6:
LCD glass is not connected; resistor current is not included.
7:
48 MHz maximum frequency at 125°C.
