13 years agocyclone V static power
We recently designed and built a new PCB with a Cyclone V part on it. The part we used is 5CEFA7U19I7N. We are seeing static power consumption that is around 4x the "typical" amount predic...

13 years agoI am absolutely sure we are measuring static power.
I just got confirmation from a personal contact at a large defense contractor that they are seeing the same problems. They said in an email to me: Power consumption is a BIG issue. Altera has been prescreening parts in order to meet the power specifications as they were specified initially. Supposedly Altera is having problems with yield/process variation. The 2.5 VCCaux that powers the configuration memory seems to be a major culprit. This voltage rail is drawing substantially more current than advertized originally. Altera is definitely aware of the issue, you have to alert them that you are having problems.
