These parameters are characterized but not tested.
Data in "Typ" column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only and are not
tested.
This is the limit to which VDD can be lowered without losing RAM data.
The supply current is mainly a function of the operating voltage and frequency. Other factors, such as I/O pin loading and
switching rate, oscillator type, 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 configured as inputs, pulled to VDD
MCLR = VDD; WDT enabled/disabled as specified.
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 configured as iputs and tied to VDD or VSS.
