Beverly, MA - October 9, 2003 -Clare, Inc., an IXYS company (NASDAQ: IXYS - News), today announced the availability of the CPC1810 solar cell product and the introduction of a new solar cell technology. The CPC1810 solar cell is activated by either natural sunlight or artificial light and produces a floating source voltage, up to 7.5 V and current output of 12 micro amps. Initial samples are packaged in a 4 pin TO-39 can with a clear surface for light transmission. Additional package options will be available in the near future as well as individual die or whole wafers.

The enabling capability behind the CPC1810 solar cell is Clare's photovoltaic technology. Clare is a leader in photovoltaic technology as a result of 20 plus years of experience using photovoltaic cells in its optically coupled solid-state relays. These photovoltaic cells are manufactured using Clare's state of the art, Silicon-On-Insulator (SOI) technology.

"It's an innovative solution for true wireless power, especially if one realizes that the standard silicon solar cells produce only 0.6 volts of output. This one solar IC product, is indeed revolutionary since it produces more than 7 volts and thus can charge batteries directly, and naturally we envision it in any battery powered product," commented Dr. Nathan Zommer CEO of IXYS Corporation. "We are proud of this achievement which brings a renewable solar energy source to power portable electronic products, and which also extends the life of regular and rechargeable batteries in these applications."

The solar cell SOI technology is scalable. As a result, Clare is currently developing additional solar cell products for higher voltages and currents that different applications require. An entire family of parts ranging from 2V to 30V with a variety of output currents will soon be introduced. Additionally, since there is excellent electrical isolation between circuit elements on the photovoltaic die, it is possible to add other power management circuitry or logic control options with minimal added cost to the product.

"We can add mixed signal IC building blocks, as desired and needed by any of our customers, to satisfy their specific battery charging needs, or quiescent power budget. The CPC1810 is just the beginning of an entire new high voltage output solar cell product family enabling Clare to take its existing technology to new markets," said John Battaglini, Marketing Director at Clare. "As the world continues to go wireless and portable electronics proliferate, the applications for this part and product extensions are limitless. This product family is also available in die form, for slim profile applications like smart cards, and electronic car alarm keys."

The CPC1810 replaces discrete component solutions while offering the advantages of semiconductor miniature size and reliability. The CPC1810 solar cell is ideal for use in a variety of applications including solar battery chargers, battery operated equipment, portable electronics, consumer applications, off grid installation, wireless sensors and detectors, self- powered sunlight/light detection and remote installation products. It can provide trickle charge to battery-operated systems thus increasing battery life, and preventing total discharge, or non-operation due to battery drain.

Pricing and Availability
Evaluation samples of the CPC1810 will be available by the end of October with production scheduled for the first quarter in 2004. For OEM quantities of 10 thousand, the CPC1810 is priced at $1.00 with a standard lead-time of twelve weeks ARO.
