cyclone III power

Another question. If you look at the Cyclone 3 static power spec in the chart on their web site, it's hard to tell how they pulled 50% out of that. I'm using a relatively small cyclone 2 chip (2C8 in...

Hi,

There is some circuitry in the device that burns static power independent of the# of LEs in the device. Grabbing the EPE from altera.com (http://www.altera.com/support/devices/estimator/cy3-estimator/cy3-power_estimator.html) is the best way to see this for yourself.

As for temperature dependence, you can see the impact of temperature in the EPE by selecting "User Entered Tj" and typing in the temperature point of interest. Repeat for various temperatures and record the results. Until we release I-specs, extrapolating this curve to 100C isn't a bad guess :-)
