11 years agoCYCLONE V FPGA Thermal Resistances
I am gonna use the following model of CYCLONE V FPGA (With device number 5CGXFC3B7U15C8N) and as I checked on the website for the values of the 6 thermal resistances (http://www.altera.com/support/devices/packaging/specifications/pkg-pin/dev-package-listing.jsp?device=cyclone_v), I found the following numbers:
26.5 223.3 20.3 18.6 5.7 11.0 It was really impressive that the 2rd value (θ[sub]ja[/sub] (° c/w) at 100 ft./min.) is 10 times bigger than the first one (θ[sub]ja[/sub] (° c/w) still air) !!! An in comparison with the values of all the other models, I tend to think that there is a typo-mistake there (it is 23.3 and not 223.3). But is it possible to confirm that? Thank you very much in advance!
