Austin, TX and Jacksonville, FL – December 3, 2002 – CMX Systems, popular manufacturer of real-time operating systems and embedded TCP/IP software, and Cygnal Integrated Products, manufacturer of 8051 Flash microcontrollers, today announced the availability of an Embedded Ethernet Reference Design featuring the CMX-MicroNet™ TCP/IP stack and the Cygnal C8051F124DK Development Kit.

The Reference Design includes a demonstration version of the CMX-MicroNet software. CMX-MicroNet is a small TCP/IP software stack that has been developed to provide Internetworking connectivity tools to designers working with 8-bit processors. It uses Cygnal’s C8051F12X 8-bit microcontroller market which has 128K byte Flash memory, 8K bytes of RAM, and 12-bit A/D convernter. With the addition of TCP/IP support, these devices provide an excellent web server platform for a wide range of industrial and commercial applications.

Chuck Behrmann, President and CEO of CMX, said, “We are very pleased that Cygnal has selected CMX-MicroNet as a networking tool for the C8051F12X family. Cygnal and CMX can now offer their customers an unmatched combination of price and performance, and this powerful combination of hardware and software will be able to work ‘out of the box’ for embedded systems developers.”

Cygnal’s Ethernet Reference Design includes:

- C8051F124DK development kit ($149)
- AB2 Ethernet Prototyping Board ($50)
- Supporting documentation and software.

CMX-MicroNet is a scaled down TCP/IP software stack with a total memory footprint of 3Kb - 20Kb, depending upon configuration, for 8-bit processors or those 16-bit processors that require a single-chip solution with no external memory. CMX-MicroNet supports more 8-bit and 16-bit microprocessors than any other existing solution. CMX-MicroNet is currently available, starting at $5,500 for the base system. All CMX software includes complete source code, no royalties on shipped products, and free technical support/updates.
