True TCP/IP Networking on 8- and 16- and 32-Bit Processors!
CMX MicroNet
Finally, the Right Connectivity Solution for Your 8-bit, 16-bit and 32-bit Embedded Processors

CMX-MicroNet has been developed by the company that is famous for providing complete, elegant solutions to the embedded community - CMX! Our developers have the expertise and hands-on experience to satisfy the most stringent real time demands that the 8-, 16-, and 32-bit community deals with every day. When we set about the task of creating the first true TCP/IP stack for these popular processors, we knew that it had to have:

Only Industry Standard Protocols. Of what benefit are closed, proprietary protocols that constrain and confuse your development team? CMX-MicroNet offers only industry standard protocols running right on your target processor and we provide full source code with every sale!

Use your Current Processor. Why should you have to upgrade your current processor, or, worst yet, add another processor just for TCP/IP? Those hardware costs can really add up! CMX-MicroNet allows you to work with your current design and still implement the networking connectivity you need.

An Affordable Pricing Structure.
CMX-MicroNet offers a low, one-time fee and no royalties on deployed products. And you get the entire source code for free with every purchase!

Looking for an Out-of-the-Box Experience???

CMX-MicroNet has been ported to dozens of commercially available evaluation boards that, collectively, feature virtually all of the supported processors listed on this page. This means that you now can benefit from out-of-the-box TCP/IP stack/hardware integration without being constrained by any one hardware vendor's offerings. In fact, you can be prototyping your application within minutes of receiving any of these evaluation boards and CMX-MicroNet!

Please contact CMX for the latest list of supported evaluation boards -- we add new boards regularly.


CMX-MicroNet has been designed for maximum portability and is written in 100% standard C code. As a consequence, some clients have decided to port the software to processors not yet supported directly by CMX, including microprocessors, microcontrollers and DSPs. Our developers are confident that designers familiar with their target processor can easily perform the port themselves. Contact CMX for an in-depth discussion with one of our developers about this option.
