Power due to capacitive loading on output pins is (first order) a function of the capacitive load and
frequency at which the outputs change.
in the IO cells as a function of capacitive load. In these cases:
Total Power = Σ((Intercept +Slope*Cload)*frequency/10MHz)
where:
Because of the low duty cycle on most device pins, power dissipation due to capacitive loads was found
to be fairly low when averaged over a period of time.
E, the external [static component], reflects the effects of placing resistive loads on the outputs of the
device. Sum the total of all V
0.5 for the purposes of these rough calculations. For instance, if there is a total of eight PWM outputs
driving 10mA into LEDs, then P = 8*.5*.01 = 40mW.
In previous discussions, power consumption due to parasitics associated with pure input pins is ignored,
as it is assumed to be negligible.
