California Micro Devices to License Patented Termination Technology; New Concept Solves Termination Problems for System and IC Designers.

Business Editors/High Tech Writers

MILPITAS, Calif.--(BUSINESS WIRE)--Nov. 27, 2000

California Micro Devices (NASDAQ NMS: CAMD) today announced that it intends to license its new patented termination technology, thus creating an additional element in its business model.

California Micro Devices (CAMD), a leading manufacturer of Integrated Passive Devices (IPDs) and complementary semiconductors, has developed significant expertise in all forms of high-speed transmission line termination. A new, patented technology, to be marketed under the trademark EZTerm(TM), solves transmission line termination problems through the use of a semiconductor-based solution instead of the traditional passive component approach. As a result, it can be designed directly into an Integrated Circuit (IC) without any special processing or added cost. The Company has already been issued two patents in this area with several additional applications in process.

When high-speed digital signals travel along the wires (lines) in a system, the signals can become badly distorted if the lines are not properly terminated. This then creates noise and radio frequency interference, leading

to system errors and malfunctions. The task of terminating the lines has typically been done with discretes, primarily resistors, placed on the printed circuit board.

The new technology is a semiconductor circuit that can be designed into the IC at the input or input/output pin. It provides both termination and electrostatic discharge (ESD) protection in essentially the same on-chip area normally occupied by the ESD protection circuitry.

Jeffrey Kalb, President and CEO of California Micro Devices, said, "We are really excited about this new technology and the value it provides to IC and system designers. It is not uncommon in today's high-speed systems to find integrated circuits completely surrounded with extra resistors or other components to control termination problems. Our technology represents an elegant solution to the problem and allows the designer to remove all of those extra components, saving space, money, and design time. It represents a real ease-of-use breakthrough for the system designer, and a marketing advantage for the IC manufacturer."

Mr. Kalb continued, "We think this is a major breakthrough and it was the featured cover article for the November 20, 2000 issue of Electronic Design magazine at http://www.elecdesign.com/. The vast majority of digital integrated circuits could benefit from the inclusion of this technology. We will make licenses available at attractive prices so designers will not hesitate to use our new termination technique. We are looking forward to widespread adoption of this exciting new technology."

It is anticipated that the new technology will be most applicable in high speed, low voltage designs such as those found in computer motherboards, computer peripherals, embedded systems, routers, switches, and other computation and communication-oriented systems.
