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 VSS,
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
= VDD; 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).
