CSR to provide BlueCore Silicon for Motorola iRadio wireless audio car adapter

Cambridge, UK - May 30, 2006 - CSR plc (LSE: CSR.L) today announced that the company will provide BlueCore3-Multimedia (BlueCore3-MM) silicon to Motorola for use in the company's RCKT-100 wireless audio car adapter and handsfree unit. The BlueCore3-MM will provide the RCKT-100 with the ability to stream digital audio from a Motorola iRadio®-enabled phone to a compatible car stereo via a stereo Bluetooth link.

BlueCore3-MM will provide the RCKT-100 with handsfree functionality with caller ID support, CSR's Clear Voice Capture (CVC) technology and the new Bluetooth Handsfree Profile (HFP) v1.5 in order to improve voice quality. The Bluetooth RCKT-100 adapter, launched at CES 2006, will be available later this year.

Additionally, CSR's BlueCore3-MM delivers a host of Bluetooth profiles to give the Motorola RCKT-100 added functionality, including A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio/Visual Remote Control Profile). The AVRCP profile permits the RCKT-100 to wirelessly control the audio from a Bluetooth enabled handset. The A2DP profile allows high quality stereo music to be received by the RCKT-100 adapter and then channeled through the car speaker system. As the software on the iRadio-enabled phone detects the presence of a trusted A2DP link it will automatically re-route the music without the need for any additional effort. 

BlueCore3-MM also implements the HFP profile with caller ID support. The new Bluetooth profile, designed for handsfree voice calling, has enhanced voice quality and allows phone information to be displayed on the car's radio display

The award-winning Motorola iRadio is a subscription based digital radio service providing over 600 channels of digital radio music and talk programs.

Anthony Murray, Vice President Automotive Strategic Business Unit at CSR commented, "Convergence is an increasingly important topic in today's mobile industry and more consumers are demanding more from their gadgets, be they mobile phones, cars or computers. Motorola's innovative products are driving a new level of convergence where functions of one device can be seamlessly transferred to the interface of another. CSR is working hard to ensure that our partners are not hindered by technological constraints in their work towards true seamless, wireless mobility."
