COMPLEX PROGRAMMABLE LOGIC DEVICE (CPLD) MODULE
A Complex Programmable Logic Device (CPLD) is a cool piece of hardware to have in your repertoire and it can be used to learn logic or a high level design language or replace obsolete functions or chips. But a CPLD needs a little bit of support infrastructure to become usable, and that’s what I’ll be walking you through here. So if you’re interested in learning CPLDs, or just designing boards for them, read on.
The design itself tries to utilize through-hole parts and a socket for the CPLD so that you could more easily build it yourself without a lot of surface mount soldering. With that said, the oscillator is a surface mount device (SMD) just due to the cost and size of its through-hole counterpart.
