This is the limit to which V

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 high-impedance state and tied to V
and all features that add delta current disabled (such as WDT, Timer1 Oscillator, BOR, ...).
For RC oscillator configuration, current through R
be estimated by the formula Ir = V
The LVD and BOR modules share a large portion of circuitry. The I
additive. Once one of these modules is enabled, the other may also be enabled without further penalty.
