Device Typ Max Units Conditions
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 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;
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 is disabled (ENVREG tied to V
SS).
5: Voltage regulator is enabled (ENVREG tied to V
DD).
6: Resistor ladder current is not included.
7: Connecting an actual display will increase the current consumption depending on the size of the LCD.
