ATtiny12 Typical
Characteristics

ATtiny11/12
The following charts show typical behavior. These data are characterized, but not
tested. All current consumption measurements are performed with all I/O pins config-
ured 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
ing frequency of I/O pin.
The parts are characterized at frequencies higher than test limits. Parts are not guaran-
teed to function properly at frequencies 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.
