CMX Ports CMX-MicroNet TCP/IP Stack to HCS12 Embedded Microcontrollers

9/22/2003 - CMX Systems, well-known designer of real-time operating systems and TCP/IP software announced the availability of the CMX-MicroNet TCP/IP stack ported to the HCS12 series of embedded microcontrollers. CMX also announced that it has been selected by Motorola as a TCP/IP Partner for this important embedded platform. 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 and 16-bit processors. The HC12/HCS12 series of microcontrollers enable 16-bit design engineers to take advantage of lower-cost Flash memory and realize fast, re-programmable embedded system designs using off-the-shelf microcontrollers.

CMX and Motorola have executed a formal agreement to cooperate closely on development and marketing activities for CMX-MicroNet for the HC12/HCS12 processor family to provide an excellent networking connectivity solution for the embedded marketplace.

The base CMX-MicroNet software package currently includes UDP, TCP, IP, Modem, SLIP, ICMP Echo, and Virtual File. Current Add-On Options available for CMX-MicroNet are: HTTP Web Server, FTP, SMTP, PPP, Ethernet, Wireless Ethernet, DHCP, and more. With hundreds of design wins around the world, CMX-MicroNet is the best tested and proven small TCP/IP stack available on the commercial market today.

Chuck Behrmann, president and CEO of CMX, said, "We are very pleased that Motorola has selected CMX, from among many potential TCP/IP vendors, to provide CMX-MicroNet as a networking tool for the HCS12 series of microcontrollers (MCUs). Motorola can now offer its customers an unmatched combination of price and performance."

Daniel Hoste, newly appointed vice president and general manager of Motorola’s 8/16-Bit Products Division, said, "Designs such as the CMX-MicroNet TCP/IP stack are an excellent demonstration of how well our HCS12 technology works with leading-edge systems. The highly efficient HCS12 instruction set enables the CMX-MicroNet TCP/IP stack to be one of the smallest that I have seen, freeing more memory for the primary application which benefits the final consumer using the internet."

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 microcontrollers and 16-bit microcontrollers. CMX-MicroNet supports more 8-bit and 16-bit microcontrollers than any other existing solution. CMX-MicroNet is currently available, starting at a suggested retail price of $5,500 for the base system. All CMX software includes complete source code, no royalties on shipped products, and free technical support/updates.

About Motorola’s/HCS12 Microcontrollers
Motorola’s HCS12 family roadmap features pin-compatible devices with on-chip Flash memory ranging from 32 K bytes up to 512 K bytes. As some customers have multiple models of a product, each with different features, embedded systems designers can employ HCS12 derivatives with the varying amounts of Flash memory for different models of end products without re-designing the "insides" of a system.

The Background Debug(tm) Mode (BDM) on HCS12 MCUs uses a single-pin interface and is engineered to enable real-time, non-intrusive, in-circuit emulation without traditional emulator limitations related to speed, voltage, capacitance or mechanical interfaces. Embedded system design engineers may emulate a system in real time while viewing and modifying memory. This allows tuning of system performance by monitoring results and changing parameters.
