We recommend using the Ultra37000 CPLD devices for new designs. The Ultra37000 CPLDs is a different family of products with a higher density. The Ultra37000 CPLDs will require PCB changes and the source code to be retargeted and recompiled. The datasheet for the Ultra37000 devices is available on our website.
