CMX-MicroNet TCP/IP Stack Ported to Century Embedded Network Microcontrollers

4/14/2003 - CMX Systems, well-known designer of real-time operating systems and TCP/IP software and Century Semiconductor, leading manufacturer of embedded network microcontrollers, announced the availability of the CMX-MicroNet TCP/IP stack ported to the CS620x series of embedded network microcontrollers. CMX-MicroNet is a very small footprint TCP/IP software stack that has been developed to provide Internetworking connectivity tools to designers working with 8-bit processors. The CS620x series of microcontrollers is widely known for offering high-performance, high-functionality general-purpose products, as well as those optimized for specific applications.

Chuck Behrmann, president and CEO of CMX, said, "We are very pleased that Century Semiconductor has selected CMX-MicroNet as a networking tool for the CS620x series of network microcontrollers. Century can now offer its customers an unmatched combination of price and performance."

President and CEO of Century, Jeff Tang said, "Century is happy that CMX-Micronet is now available to support our networking firmware efforts on the CS620x family of Embedded Network Microcontrollers. We can now offer customers the performance and reliability of CMX networking firmware."

About CMX-MicroNet
CMX-MicroNet is a scaled down TCP/IP software stack with a total ROM 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.

About Century's CS620x Embedded Network Microcontrollers
The CS620x series of Embedded Network Microcontrollers incorporate high speed 8051 cpu cores together with all on-chip hardware needed to produce a single-package embedded network server. All members of the CS620x family include on-chip Ethernet MAC and Physical Layer Interface. Additional CS620x family members include 24-bit linear address memory models and single-cycle RISC cpu cores. All CS620x series microcontrollers are 8051 LARGE memory model compatible.
