CSR plc today announced that the new Nokia Bluetooth Headset BH-200, available now, contains CSR's BlueCore3-Audio Flash (BlueCore3-AF), providing the headset with a fully compliant Bluetooth v1.2 specification for voice communications. The stylish Nokia Bluetooth Headset BH 200, the first Handsfree Profile, HFP1.5, headset, is part of Nokia's recently launched line of high-end wireless headsets with CSR's BlueCore technology for Bluetooth at the core. CSR's leading interoperability pre-testing and support reassures users that the Nokia Bluetooth Headset BH-200 can be paired with any Bluetooth enabled mobile handset.

Weighing just 14g with dimensions of 49 x 22 x 21 mm, the Nokia Bluetooth Headset BH-200 achieves a talk time of 5 hours 30 mins and standby time of an impressive 150 hours. The headset's simplistic design offers individual button control for power, call answering, volume, and mute functions. The Nokia Bluetooth Headset BH-200 also supports the voice recognition function of compatible mobile handsets.

CSR's BlueCore3-Audio Flash is a cost-effective and compact single-chip radio and baseband IC designed for Bluetooth devices that require an on-chip mono CODEC and 6Mbits of embedded Flash memory. When combined with CSR's Bluetooth software stack, BlueCore3-AF provides designers with a fully compliant Bluetooth v1.2 solution for voice. External components are further reduced thanks to an on-chip 1.8V regulator, and a charger for lithium batteries. BlueCore3-AF also supports HFP1.5 as well as incorporating auto-calibration and built-in self-test (BIST) routines to simplify development, type approval and production tests.

Razvan Olosu, Vice President, Enhancements, Nokia, said, "The Nokia Bluetooth Headset BH-200 enhances everyday mobility by combining the highest quality Bluetooth technology with simple and functional design. CSR's BlueCore3-AF allowed us to design a headset that achieves the highest level of connectivity and interoperability without sacrificing its compact design. We were able to concentrate on the style and form of the headset with the confidence of knowing that CSR's technology produces the simplicity and performance expected from all of Nokia's products."

Gordon Petrie, VP, Sales Europe for CSR commented, "The use of BlueCore3-AF in the Nokia Bluetooth Headset BH-200 further demonstrates CSR's commitment to providing designers with complete wireless offerings that minimise the amount of external components required for production. CSR will continue to work towards alleviating design, time, and price constraints involved in wireless device production, enabling manufacturers to add more value to their product offerings and concentrate on differentiation."

About CSR

CSR plc is the leading global provider of Bluetooth technology and has developed expertise in other single-chip wireless communication standards such as Wi-Fi (IEEE802.11). CSR offers developed hardware/software solutions for Bluetooth based around BlueCore, a fully integrated 2.4 GHz radio, baseband and microcontroller.

CSR has now launched its fifth generation BlueCore suite and is in volume manufacture of its fourth generation BlueCore devices. BlueCore4 supports the Enhanced Data Rate (EDR) standard, which was ratified at the end of 2004. BlueCore4 remains the only EDR silicon to be shipping in volume today. In November 2004 CSR launched UniFi, the first single chip 802.11a/b/g embedded solution specifically targeting the mobile phone and consumer electronics markets.

BlueCore features in over 50 per cent of all Bluetooth devices shipped and over 60 per cent of all qualified Bluetooth enabled products and modules listed on the Bluetooth website with industry leaders including Nokia, Dell, Panasonic, Sharp, Motorola, IBM, Apple, NEC, Toshiba, RIM and Sony using BlueCore devices in their range of Bluetooth products.

In March 2005, CSR acquired Clarity Technologies Inc., for its Clear Voice Capture (CVC) technology that enhances the audio performance of any voice-based product or system. Applications for CVC include wireless headsets, handsets and automotive hands free systems.

In August 2005, CSR completed the acquisition of UbiNetics' software business, providing a strong R&D team to accelerate its existing software development in Bluetooth, Wi-Fi and UWB. The UbiNetics team gives CSR the capacity to extend its offering to mobile handset customers.

CSR has its headquarters and offices in Cambridge, UK, and offices in Japan, Korea, Taiwan, China, India, France, Denmark, Sweden and both Texas and Detroit in the USA.
