Note 1: A device’s I
DD supply current is mainly a function of the operating voltage and frequency. Other factors,
such as PBCLK (Peripheral Bus Clock) frequency, number of peripheral modules enabled, internal code
execution pattern, execution from program Flash memory vs. SRAM, I/O pin loading and switching rate,
oscillator type as well as temperature can have an impact on the current consumption.
2: The test conditions for I
DD measurements are as follows: Oscillator mode = EC+PLL with OSC1 driven by
external square wave from rail to rail and PBCLK divisor = 1:8. CPU, Program Flash and SRAM data
memory are operational, Program Flash memory Wait states = 7, program cache and prefetch are dis-
abled and SRAM data memory Wait states = 1. All peripheral modules are disabled (ON bit = 0). WDT
and FSCM are disabled. All I/O pins are configured as inputs and pulled to V
SS. MCLR = VDD.
3: Data in “Typical” column is at 3.3V, 25°C at specified operating frequency unless otherwise stated.
Parameters are for design guidance only and are not tested.
4: This parameter is characterized, but not tested in manufacturing.
