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
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 hi-impedance state and tied to V
For RC osc configuration, current through R
estimated by the formula Ir = V
Timer1 oscillator (when enabled) adds approximately 20 A to the specification. This value is from
characterization and is for design guidance only. This is not tested.
