These parameters are characterized but not tested.
Data in “Typ” column is at 5V, 25C unless otherwise stated. These parameters are for design guidance only
and are not tested.
Note 1: This is the limit to which VDD can be lowered in SLEEP mode without losing RAM data.
2: 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 tristated, pulled to VDD.
MCLR = VDD; WDT enabled/disabled as specied.
3: Measured with all inputs at rails, no DC loads. IPD1 measured with internal oscillator active.
4: IDD values of individual analog module cannot be tested independently but are characterized.
5: Worst-case IPD conditions with all conguration bits unprogrammed. Programming conguration bits
may reduce IPD.
