Looks like LQFP64_14 is probably compatible with what you want. It is a 64 pin, 14mm square body, 0.8mm pitch. Please verify that before using it. Speaking as one who checks in a lot of footprints, the best way is to attach the submission to a RFE (request for feature enhancemnet) on the pcb sourceforge project page. Especially on a package such as a TQFP where there is a whole family of footprints, I like to add as much of the family as possible at once. If you are able to provide a URL to a reference for the footprints, that is highly desirable as I don't like to add any footprints that I have not checked over myself. Attaching them to a RFE will let others have access to them before they're checked in and its a good way to help me not lose them as sometimes I have more time for PCB than other times. -Dan --
