CSR provides Bluetooth connectivity for Motorola iDEN handsets in the US

Cambridge, UK - June 6, 2006 - CSR plc (LSE: CSR.L) announced today that the latest Motorola Integrated Digital Enhanced Network (iDEN) handsets are endowed with CSR's BlueCore3-ROM cellular Bluetooth IC.  Following the successful trail of the first iDEN handset - the i605, the Motorola i870, i615, and i580 are the latest Motorola iDEN handsets to feature Bluetooth connectivity by CSR and are currently available in the United States.

Motorola's iDEN network is designed for mobile business applications offering advanced wireless technologies such as two-way digital radio, Bluetooth, Push-To-Talk (walkie-talkie), MotoTalk (off network walkie-talkie), digital wireless telephony, alphanumerical messaging, and data/fax capabilities.  The iDEN handsets feature speakerphone, voice command, mobile Internet and e-mail, wireless modems and voice activation, providing full connectivity on the move as well as a full autonomous + assisted GPS receiver. 

CSR's BlueCore3-ROM is a fully compliant, single-chip Bluetooth V1.2 platform allowing wireless connection to other Bluetooth devices such as headsets, PDAs, and other mobile handsets.  BlueCore3-ROM was the first IC in the industry featuring advanced Bluetooth V1.2 co-existence techniques such as adaptive frequency hopping (AFH), to ensure there is no interference with the other RF technologies in the end product.  In addition, CSR's technology minimizes the external components required, ensuring production costs and real-estate on the circuit board are minimized.

Matthew Phillips, SVP of CSR's handset connectivity SBU commented, "Bluetooth connectivity is critical for all new mobile handsets.  However, designers constantly face size, coexistence, and time to market issues.  BlueCore offers a complete silicon and software solution designed for the smallest of products with the most advanced functionality, thus enabling companies to concentrate on other areas of handset design and differentiation."
