(EMAILWIRE.COM, December 10, 2002 ) BlueCore2-CDMA is designed solely for mobile handset applications with features aimed at integration simplicity, co-existence, power savings and size reduction. BlueCore2-CDMA is CSR's first radio-only Bluetooth device and is tailored specifically for connection to the QUALCOMM CDMA Technologies (QCT) MSM5100TM Mobile Station Modem (MSMTM) chipset.

BlueCore2-CDMA offers small size and minimal external components providing designers with greater freedom to produce smaller, lighter and more ergonomically designed products. It is fully BQB qualified with samples available now. Shipping in volume is expected beginning Q1 2003.

CSR's BlueCore2-CDMA requires fewer external components than previous designs using integrated loop filter components and linear voltage regulators. With a low component count and a footprint of as little as 50mm2 for the total Bluetooth solution, the BlueCore2-CDMA product allows CSR to target high-volume, cost-sensitive applications for Bluetooth such as the CDMA and 3G mobile handsets supported by QUALCOMM.

John Halksworth, product manager for the CDMA device, commented, "BlueCore2-CDMA brings CSR's industry-leading CMOS radio to a new market segment at a cost point that will allow Bluetooth to become a mandatory feature on mobile handsets." Halksworth continued, "We used the same radio and control architecture as the other devices in the BlueCore2 range, which account for 57 percent of v1.1 qualified end products, then optimized it for co-existence with the MSM series devices."

Supplied in a small CSP (chip scale package), BlueCore2-CDMA is implemented in a 0.18-micron CMOS process, which has a proven track record with the BlueCore2-External that has been in mass production since Q4 2001.

CSR was the first company to market with its single-chip BlueCore and has continued to lead the market on price, size and availability, further enhancing CSR's leadership position in the Bluetooth market.

About CSR

CSR (Cambridge Silicon Radio) specializes in providing single-chip radio devices to the global market for short-range wireless communications, including Bluetooth. The company's mission is to create the most highly integrated radio devices available, fabricated using standard CMOS technology, to provide its customers with the lowest cost of ownership of high-quality digital radio.

CSR was the first company in the world to offer a true single-chip Bluetooth solution with BlueCore, a fully integrated 2.4 GHz radio, baseband and microcontroller. In Q4 2001 CSR released BlueCore2, its second generation family, and offers developed hardware/software bundles for each of the fastest growing Bluetooth applications markets. Users can combine the chips with the CSR Bluetooth software stack to provide a fully compliant solution for data and voice communications or, used with an upper layer host software stack, CSR is able to offer a complete Bluetooth end-to-end solution.

CSR has a growing list of major international companies including Microsoft Corp, Samsung, Sony, Compaq, IBM, Fujitsu, LG, ALPS, TDK, 3Com, Mitsumi, Siemens and Motorola, who have already used CSR's BlueCore in the development of a range of Bluetooth products. In fact, 70 percent of available pre-qualified modules, as listed on the qualified products page of the Bluetooth Special Interest Group (SIG) web site, feature BlueCore and it is in 57 percent of all qualified Bluetooth v 1.1-enabled end product designs.

CSR is headquartered in Cambridge, UK, with offices in Richardson, Texas; Tokyo, Japan; Singapore and Aalborg, Denmark.
