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 high-impedance state and tied to V
DD or VSS and all features that
add delta current disabled (such as WDT, Timer1 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 or VSS;
MCLR
= VDD; WDT enabled/disabled as specified.
3: When operation below -10°C is expected, use T1OSC High-Power mode, where LPT1OSC (CONFIG3H<2>) = 0.
When operation will always be above -10°C, then the low-power Timer1 oscillator may be selected.
4: BOR and HLVD enable internal band gap reference. With both modules enabled, current consumption will be less
than the sum of both specifications.
