Other CPLD dev boards

Kamani Development Tools has the ZL4PLD_9572 dev board, which features an onboard voltage regulator and ISP connector. The preassembled board is designed in a 40 pin DIP breadboard compatible form, and sells for €13.36, plus €30 for shipping to EU countries. AWC sells the PBX84 Xilinx Prototyping Board, in several different configurations beginning at $49.95 […]

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 […]

Re-animating the PDP-11/70 with CPLD, ethernet

J. Peterson updated a PDP-11/70 console with an ethernet controller and a CPLD to control the blinking LEDs: I’ve always missed that visual and tactile aspect of computers that’s been lost since the advent of microprocessors. When a console for a PDP-11/70 came up for sale on Ebay, I couldn’t resist the opportunity to bring […]

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: XC9572XL 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 Xilinx XC9500XL family has some of the cheapest and readily-available […]

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 […]

Trivia: CPLD on a PDIP?

Atmel produces what are believed to be the only CPLD devices sold in PDIP form: the ATF2500C and ATF750C . These devices are priced at between $5 and $8 at Digikey and Mouser. Programming hardware and software is available from Atmel. Atmel provides free design software known as WinCUPL, which mainly supports programming in the […]

Week in (p)review: February 20, 2011

Don’t forget to share your current project in the comments or the forum. This week our favorite project gets a free SOIC protoboard. Here’s a summary of major developments over the last week: A new firmware and PC application to program CPLDs and FPGAs with the Bus Pirate MOD for the phpBB3 forum stops almost […]

PROTOTYPE: XT IDE disk controller with CPLD

We’re releasing a stalled or abandoned prototype every few days while Seeed Studio is on break. We put a lot of work into these projects, but they’re still missing major components and testing. If an abandoned project sparks your interest, we may have PCBs to get you started. The XT-IDE project is a Vintage Computer […]

App note: Interface SDRAM and DDR SRAM with a CPLD

irrenhaus tipped us to demo projects that interface SDRAM and DDR SRAM with CoolRunner-II CPLDs: There is a reference implementation from xilinx how to interface a SDRAM memory from a CoolRunner-II CPLD  XAPP394: “Interfacing to Mobile SDRAM with CoolRunner-II CPLDs” and XAPP384: “Interfacing to DDR SDRAM with CoolRunner-II CPLDs”). So my idea was: Why not […]

Altera CPLD/FPGA Quartus II design tutorials

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.

Xilinx free FPGA/CPLD design tutorials

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 […]
