Note 1: Data in “Typical” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance
only and are not tested.
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 I
DD measurements are as follows: OSC1
driven with external square wave from rail to rail. All I/O pins are configured as inputs and pulled to V
SS.
MCLR
= VDD, WDT and FSCM are disabled. CPU, SRAM, program memory and data memory are
operational. No peripheral modules are operating; however, every peripheral is being clocked (PMD bits
are all zeroed).
