Legend:  
Shading of rows is to assist in readability of the table.  
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 VDD 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 IDD measurements in active operation mode are:  
OSC1 = external square wave, from rail-to-rail; all I/O pins tri-stated, pulled to VDD;  
MCLR = VDD; WDT enabled/disabled as specified.  
3: For RC oscillator configurations, current through REXT is not included. The current through the resistor can be estimated  
by the formula: Ir = VDD/2REXT (mA) with REXT in k.  
4: 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.
