2: The supply current is mainly a function of the operating voltage and frequency. Other factors such as I/O pin
3: The power down current in SLEEP mode does not depend on the oscillator type. Power-down current is

and are not tested.
loading and switching rate, oscillator type, internal code execution pattern, and temperature also have an
impact on the current consumption.

Current consumed from the oscillator and I/O’s driving external capacitive or resistive loads needs to be con-
sidered.
For the RC oscillator, the current through the external pull-up resistor (R) can be estimated as: V
For capacitive loads, the current can be estimated (for an individual I/O pin) as (C
C
The capacitive currents are most significant when the device is configured for external execution (includes
extended microcontroller mode).
