Characteristics
1062F–AVR–07/06
The following charts show typical behavior. These figures are not tested during manu-
facturing. All current consumption measurements are performed with all I/O pins
configured as inputs and with internal pull-ups enabled. A sine wave generator with rail-
to-rail output is used as clock source.
The power consumption in Power-down mode is independent of clock selection.
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
where C
quency of I/O pin.
The parts are characterized at frequencies and voltages higher than test limits. Parts are
not guaranteed to function properly at frequencies and voltages higher than the ordering
code indicates.
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.
