Typical characteristics – PRELIMINARY DATA
The following charts show typical behavior. These data are characterized, but not tested. All current consumption measure-
ments 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

V
CC
*f where C
L
= load capacitance,
V
CC
= operating voltage and f = average switching 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 differential current drawn by the watchdog timer.
