95 / 112 page 95 AT90S8515 0841G–09/01 Typical Characteristics 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. ICP is pulled high externally. 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 L • VCC • f where CL = load capacitance, VCC = operating voltage and f = average switching 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.
