Business Editors/Technology Writers

RICHARDSON, Texas--(BUSINESS WIRE)--May 7, 2001

CSR (Cambridge Silicon Radio), a single-chip Bluetooth company, announces the opening of its San Jose office and the formation of a premier external North American sales force, through contracts with several well-established manufacturers representative companies: EIR, J-Squared and SSI (Eastern Region); Beta Technology, Bonser-Philhower Sales and Luscombe Engineering (Central Region); Luscumbe Engineering, Moulthrop Sales, and Westrep (Western Region); J-Squared (Canada).

John Hodgson, CSR's CEO, comments on the decision to open a second U.S. location in San Jose: "Now that CSR has internal and external sales reps building relationships all over the U.S., it's time to expand our operations to meet our customers growing needs. Opening a San Jose office puts CSR close to Silicon Valley customers and is a great complement to our U.S. headquarters in Richardson, Texas."

CSR's new external sales force, which includes its first North American partner Moulthrop Sales, is part of the company's creation of territory-based sales channels that work to meet the increasing demand for CSR's Bluetooth products throughout North America. CSR and its new high-tech sales partners are combining talents to deliver Bluetooth technology to an impressive portfolio of customers. These manufacturers representatives offer precise roadmaps for OEMs to quickly and cost-effectively implement single-chip Bluetooth technology. CSR will provide OEM customers with the benefit of easy access to reference design schematics, detailed bill-of-materials estimates, as well as application notes facilitating deployment of the award-winning CSR BlueCore(TM)01 design for a

host of industrial and consumer applications.

According to Eric Janson, CSR's North American vice president of sales, marketing and applications engineering, "CSR chose these sales partners carefully. We wanted reputable companies with seasoned, long-tenure sales professionals who know the design-in process and have relationships with top customers." Janson adds, "These rep companies are quickly ramping up their Bluetooth and wireless networking know-how to align with the special needs of their customers and CSR's sales goals. In addition, several representatives have complementary products on their line card, which allows CSR to focus on core engineering competencies and establish a strong presence in the U.S."

CSR aims to lower the cost and size of Bluetooth silicon with their first-to-market, SIG qualified, true single-chip, BlueCore01. CSR's Bluetooth solution includes the industry's first integrated CMOS based radio, baseband and microcontroller. Together with external flash ROM containing the CSR Bluetooth software stack and CSR's CMOS radio frequency (RF) transceiver, complete with support for USB connection to a PC. The design is optimized to require very few external RF components to allow a rapid design of the motherboard, and therefore the fastest possible time-to-market at the lowest overall cost.
