The Cmod, or Carrier Module, family of products is designed to offer quick, simple, and flexible integration of an FPGA into circuit design, prototyping, and learning/hobby projects.

The Digilent Cmod S6 is a small, 48-pin DIP form factor board built around a Xilinx® Spartan®-6 LX4 FPGA that brings FPGA power and prototyping to a solderless breadboard.

The board includes a programming ROM, clock source, USB programming and data transfer circuit, power supplies, and basic I/O devices. There are 46 FPGA I/O signals that are routed to 100-mil-spaced through-hole pins, making the Cmod S6 compatible with solderless breadboards. This form factor makes the Cmod S6 a great option for flexible and affordable prototyping, or learning FPGA and digital logic circuits. At just .7" by 2.6", it can also be loaded in a standard socket and used in embedded systems.

The Spartan®-6 FPGA onboard the Cmod S6 is a legacy device and is only supported by Xilinx's legacy ISE Design Suite. See the Software tab for more details.

For newer designs, we recommend the Cmod S7, featuring the newer Spartan-7 FPGA. There is also a Cmod A7, featuring an Artix-7 FPGA, which offers additional performance and transceiver lines for more demanding applications.

Guides and demos are available to help users get started quickly with the Cmod S6. These can be found through the Support Materials tab.

  • Xilinx Spartan-6 XC6SLX4-2CPG196 FPGA
  • 600 slices (each with 4 LUTs and eight flip-flops) 
  • 8 DSP slices
  • 216Kbits of block RAM
  • 2 CMTs (4 DCMs and 2 PLLs)
  • 16 MB Spansion® Quad SPI Flash for storing FPGA configurations and/or user data
  • 46 FPGA GPIO signals brought to DIP pins
  • Two on-board clock sources
  • Requires a USB A to micro-B USB cable for configuration (not included)
  • 4 user LEDs and 2 user buttons
  • On-board Adept USB2 port for configuration, test, and communications interfaces
  • Cmod S6 Module
  • Custom Digilent cardboard box with protective foam

The Cmod S6 can be programmed with Digilent's Adept software. Digilent Adept is a unique and powerful solution which allows you to communicate with Digilent system boards and a wide assortment of logic devices. Find out more about Adept here.

To create and modify designs for your Cmod S6, you can use Xilinx's ISE Design Suite. (The Spartan-6 family of FPGA are not supported for development in Vivado design Suite.)

Quickly find what you need to get started and reduce mean time to blink.

    Board works as promised

    Posted by Digilent Customer on 8th Nov 2019

    I have successfully downloaded my designs into the FPGA and the SPI PROM using the free Xilinx ISE Webpack. It is exactly what is needed to make these ball grid array parts accessible to users without PC fab capability. I'd like to see a similar product with a much larger Spartan 6 part. I don't want to have to pay Xiinx for Vivado to gain access to the Artix family

    Great place to start learning FPGA

    Posted by Chris Courson on 23rd Feb 2018

    The CMod S6 board is easy to use and straight forward to learn FPGAs with. As a hobbyist and professional, I agonized over finding the right board to begin learning with. I am very happy with this board. The only drawbacks to learning FPGA in general is the lack of available entry-level learning material. This is true of all of the FPGA boards I considered. The Xilinx IDE is enormous in download size and runs only in on virtual machine if using Windows. No Mac support. All that aside, this board has given me a clear view of the exciting possibilities with FPGA devices.

    Great stuff with certain activation effort

    At best, use it with a carrier board (2-layer FR4) that provides ESD protection and avoids any unplugging of the device. Put some 40109 to interface 5V logic on it as well. Together with any microcontroller on the carrier, you have an unbeatable combination! There is no need for the Adept package,programming is also possible directly using Xilinx' ISE Suite (at least for the CMOD-S6).

    Great product but requires care

    Posted by Jeff on 26th Jan 2017

    As a Project Lead the Way school, we purchased a kit that included these FPGA chips. The unfortunate part was that the documentation did not explain how static sensitive the chips actually are. That lead us to have multiple modules fail from students handling them improperly. If cared for properly, these FPGA modules perform very well and are pretty affordable.

    Work is ongoing

    Aside from FedEx losing my package, declaring it delivered yet without actually delivering it (I complained to FedEx), I've so far gotten everything I've asked for of the CMod-S6. I wanted an area challenged device, and the CMod-S6 is certainly that. However, I've only just recently had it delivered, so my work with it is far from complete. You can read about what I am up to at http://opencores.org/project,s6soc. Still, I like the design, and I appreciate the support Digilent has provided. If you buy this, do be prepared to become intimately familiar with the Adept tools--you will be needing them.

    Extremely fragile!

    Posted by Digilent Customer on 16th Apr 2016

    The concept behind this product is great, I like the functionality it offers with its interaction with multisim. Unfortunately, I've never worked with electronics that have been as sensitive as these chips. I use these within a high school classroom, and had about 5 of them break within a single week of usage due to static discharge. The contact pins also break off very easily. How to expect at $70 these would last a little bit longer and be more durable.
