TBD = To Be Determined
Data in ‘Typ’ column is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance
only and are not tested.
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 disabled.
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 peripheral current is the sum of the base IDD or IPD and the additional current consumed when this
peripheral is enabled. The peripheral Δ current can be determined by subtracting the base IDD or IPD
current from this limit. Max values should be used when calculating total current consumption.
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.
