23. AT90PWM81 Typical Characteristics
The following charts show typical behavior. These figures are not tested during manufacturing. All cur-
rent 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.
All Active- and Idle current consumption measurements are done with all bits in the PRR register set and
thus, the corresponding I/O modules are turned off. Also the Analog Comparator is disabled during these
measurements.
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

The parts are characterized at frequencies higher than test limits. Parts are not guaranteed 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 differential current drawn by the Watch-
dog Timer.
