I already tried that. UltraLibrarian does not support my CAD tool. I exported the DFX and used DWG to measure the pads. The DFX files were dimensionless. If I assume that the dimensions are mils then the width of the pad is 0.35mm x 1.00mm which left 0.14mm spacing between the pads (about 5.5mil spacing). I was expecting the typical 6mils, so I either measured something else or my assumption of the dimension unit was wrong. In the end, I just downloaded the Gerbers for the Launchpad and measured the pads. Those measurements said that the pads are 0.3mm x 1.6mm, much more believable. (warning recreational griping ahead): This is a lot of trouble for customers who just wanted to search the pad library of their CAD tool for a matching footprint. In my opinion this should information should be part of the datasheet instead of requiring users to download UltraLibrarian (about 2Gb of disk space and comes with an annoying upgrade nag screen to pay for an upgrade). Most CAD tools come with pre-made library footprints so why do I have to use UltraLibrarian to get a footprint when I can just look it up? And why should I have to learn another tool chain ecosystem for information that should be part of the datasheet? If the footprint was completely different standard then yeah maybe but this is not the case with this LQFP. And why does TI make customers go through their "Where's Waldo" website jungle to find the small print that you circled above in red? You don't have to answer the above, I am just venting about TI's new one size fits all solution darling. I am using the Gerber dimensions to identify the needed footprint.
