Typical
Characteristics
The following charts show typical behavior. These data are characterized but not tested.
All current consumption measurements are performed with all I/O pins configured as
inputs and with internal pull-ups enabled.
The current consumption is a function of several factors such as: Operating voltage,
operating frequency, loading of I/O pins, switching rate of I/O pins, code executed and
ambient temperature. The dominating factors are operating voltage and frequency.
The current drawn from capacitive loaded pins may be estimated (for one pin) as
C_L•V_CC•f where C_L = load capacitance, V_CC = operating voltage and f = average switch-
ing frequency of I/O pin.
The difference between current consumption in Power-down mode with Watchdog
Timer enabled and Power-down mode with Watchdog Timer disabled represents the dif-
ferential current drawn by the Watchdog Timer.
