voidptr shared a CPLD development board he made a few years ago: i used few times some xilinx xc9572xl with pleasure (and few other sizes). i like the family 5V tolerance, so i can plug that everywhere… Via the forum.
irrenhaus posted a JTAG debugger design inspired by the Bus Blaster v2: I was developing my own version of a JTAG programmer with the FT2232H as I saw this project here. I liked the Idea with the CPLD very much and I’d love to play with CPLD’s or FPGA’s so I decided to adopt this […]
If you have an Altera development board, such as the MAX V CPLD board or the UP1, UP2 or DE series of board, Altera has a collection of free video tutorials covering many aspects of CPLD/FPGA circuit design and programming of devices using their Quartus II design software.
From the comments on our earlier CPLD post: Programmable logic meets the Arduino. The Amani 64 is a low-cost entry-level CPLD development kit, stackable with the Arduino, other Amanis, and Arduino-compatible shields. The Amani 64 by itself is a capable embedded controller but becomes an even more powerful tool when teamed up with the Arduino […]
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.
The Arduino platform and bare microcontrollers are good ways to get started in developing embedded systems. But the way of the future is clearly CPLD and FPGA architecture. These devices are not simply a new type of chip, but a new and interesting design and development frontier. Their programs are developed using several methods, including […]
A new site allows you to conduct programmable logic design with Xilinx and Altera devices “in the cloud.” PLUNIFY, currently in Beta, allows you to experiment with PLD development in your web browser without downloading any software. A free account is available allowing you to 1 GB of storage space and free online development tools […]
Altera has announced the release of their MAX V CPLD line and companion dev kit. Altera’s webcast describes the dev kit and demos a few simple examples. The MAX V family of low cost and low power CPLDs offers density ranging from 40 to 2,210 logic elements (LEs) (32 to 1,700 equivalent macrocells) and up […]
Xilinx outlines how the Coolrunner-II CPLD can be applied in portable educational toy development. Don’t forget our quick start guide for the Coolrunner-II, it explains the bare minimum circuit you need to get started with this chip.
Lattice made an over-the-top infomercial for the MachXO2 Programmable Logic Device. PLDs are in the neighborhood of CPLDs and FPGAs. Lattice CPLDs are available at Mouser, but we’ve never tried them. Any experience? This gem seems to have originated with Jeri Ellsworth, but it’s everywhere today.
