CSR plc today announced that the award winning BenQ-Siemens S88 handset contains CSR's BlueCore3-ROM silicon. The new handset incorporates the latest OLED (Organic LED) technology and v1.2 Bluetooth connectivity to support and enhance an array of integrated multimedia features. The use of BlueCore3-ROM technology and BlueCore Host Software (BCHS) further cements CSR's position as the preferred wireless connectivity partner for handset manufacturers.

The S88 features an integrated 2.0 Megapixel camera with auto focus and 16x digital zoom. High-quality video is captured with the in-built MPEG4 video recorder and all media is stored on the handset's 20 MB internal memory and external micro-SD card. The tri-band GSM handset also features an integrated music player supporting MP3 & AAC.

In order for consumers to fully appreciate the multimedia features of the S88, the handset employs the latest 2.0-inch Active Matrix OLED display (262,144 colors, 176 x 220 pixels). CSR's BlueCore3-ROM technology is at the heart of the S88 allowing the handset to print photos wirelessly to a Bluetooth-enabled printer and share its multimedia content with other Bluetooth-enabled devices.

CSR's BlueCore3-ROM silicon provides the S88 with a fully compliant Bluetooth v1.2 platform with hardware to implement error-corrected eSCO (Extended Synchronous Connection Oriented) links. BlueCore3-ROM is a complete single-chip solution with on chip microcontroller and 4Mbits ROM and has been designed to reduce the number of external components required for production. CSR's silicon also incorporates auto-calibration and built-in self-test (BIST) routines to simplify development, type approval and testing allowing production times to be reduced along with overall production costs and the bill of materials (BOM).

BenQ-Siemens' new handset also includes BCHS, which provides a fully integrated Bluetooth software solution. BCHS provides the upper layers of the Bluetooth protocol stack (above HCI, or optionally RFCOMM) plus a large library of profiles such as Hands-free profile (HFP) and Headset profile (HSP). Reduction of overall power consumption is achieved through BCHS implementing all the low power modes such as deep sleep mode which minimises the power consumption of Bluetooth when it is not in operation.

Sebastian Koh, VP Sales Asia Pacific, for CSR commented, "Bluetooth connectivity is a necessity for today's mobile devices. CSR is committed to working closely with OEMs in order to help them implement market-leading Bluetooth connectivity into their designs." Koh, added, "CSR will continue to provide the most innovative wireless silicon and software on the market that meets production cost and time to market requirements."

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.
