Larger capacity #5

It is surprising what you can do with the XC9572XL's 72 macrocell capacity, but there's also no doubt that for some jobs it is limiting. Specifically, PWM and applications like led display refresh are limited by the number of macrocells available.

There is a solution, there are larger versions of this device available. The down side is that the larger devices don't come in packages that can be through hole soldered. Some of them can be home soldered but you'll need to be competent with a soldering iron and willing to assemble surface mount devices (QFP100's are definitely possible, we've done it by hand).

If you'd like to see a larger capacity Guzunty, please register your interest by leaving a comment against this issue.

Let us know if you'd be willing to build one or whether you'd want it ready made. Bare boards would be the same cost, kits would obviously have to reflect the increased cost of the devices.

Closing this as there does not seem to be much demand for a larger capacity version.
