Xilinx CoolRunner-II CPLD starter kit
Arhi tipped us to this starter kit for CoolRunner-II CPLDs: I can highly recommend CoolRunner-II CPLD Starter Kit. I have this small board for a while and it’s more then you need to learn to use cpld’s and it’s fairly cheap ($60)… it’s of course proprietary, the atmel on board (that can be used to […]
Debugging a glitch on a CoolRunner-II project
While working on his CoolRunner-II 50Mhz counter project jbaele found a bug. The reset line was showing a serious glitch when the stop signal was sent to the counter. The glitch was found to be the result of having the stop and reset signals next to each other on a ribbon cable. The capacitance of […]

App note: CoolRunner-II character LCD module interface
Xilinx has an application note explaining how to use LCD modules with a CPLD. CoolRunner-II CPLDs can be used to control dot-matrix liquid crystal display (LCD) modules. The low-power characteristics of LCD modules make them an ideal complement to the CoolRunner-II family. These displays typically require 3.3V signals. However, this is not of concern because […]

CPLD dev-board button bouncieness
voidptr tested the bouncieness of the CPLD development board button and found it to be pretty good. XSVF and SVF files are available to download if you’d like to program the CPLD and try it yourself. that little switch is not bouncy … 1 bounce each 4 or 5 clicks … a lot better that […]
Mini robot design using CoolRunner-II CPLD
It’s National Robotics Week, and what would National Robotics Week be without a CPLD based mini robot design? Here’s a mini robot design project outline (PDF!) found in the World Academy of Science, Engineering and Technology journal. While it’s not a “how to” style article (no schematic/code provided), it describes the advantages of using CPLDs […]
Free PCB Sunday: CPLD development boards
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This week we’re giving away two […]
Week in (p)review: April 01, 2011
Don’t forget to share your current project in the comments or the forum. This week our favorite project gets a free QFP protoboard. Here’s a summary of major developments over the last week: We released XC9572XL and XC2C64A (CoolRunner-II) CPLD development boards USB IR Toy v1 and Web platform v1.1 are back in stock at […]
Xilinx CPLD schematic libraries guide
When you get your CPLD development board, you’ll want to start coding! Programs for Xilinx CPLDs are most commonly written in Verilog or VHDL, and you will find examples on our CPLD page. A third way which is usually easier for beginners is schematic entry which you can do in the free Xilinx ISE WebPack. […]
Free PCB: CPLD development boards
To celebrate the launch of our new CPLD development boards we’re giving away PCBs. Just ask for a CoolRunner-II or XC9572XL dev-board in the comments, if you have a project in mind we’d like to hear about it too. Assembled CoolRunner-II and XC9572XL development boards are available now for $15.
NEW PROTOTYPE: CoolRunner-II CPLD development board
Ever get stuck choosing the right logic chip combination or voltage level translator? Give up the hunt and create your own custom logic chip. CPLDs can give you the logic you need, with the pinout you want, while saving board space and board revisions. The CoolRunner-II XC2C CPLD has two separate banks of pins that […]
Xilinx CPLD applications handbook
This document from Xilinx could easily be titled “Everything You Always Wanted to Know About Xilinx CPLDs But Didn’t Know Where to Look.” Its the Xilinx CPLD Applications Handbook, featuring the CoolRunner-II and XC9500XL. It’s a 422 page compendium of application notes, hardware interfacing tips and specs that any Xilinx CPLD user will want to […]
Xilinx CPLDs: XC9500 vs CoolRunner-II
The two cheapest and most readily available Xilinx CPLD families are the XC9500 and CoolRunner-II. Both are in stock at DigiKey in a variety of packages, with simple devices starting at around $1. We wondered what exactly the differences are, here’s our notes in a table. More on the wiki.
