CSR Launches Most Integrated Wireless Single Chip
June 3, 2008 11:21 AM | Technology | Comments (0)
CSR today announced the launch of its seventh generation BlueCore silicon. BlueCore7 is the world’s first device integrating Bluetooth v2.1+EDR, Bluetooth low energy, eGPS (enhanced Global Positioning System), and FM transmit and receive technologies on a single chip. CSR’s BlueCore7 significantly reduces the power, size, cost and complexity of adding multiple radios into a mobile phone and demonstrates the company’s continued expertise in embedded wireless technologies. CSR has integrated Bluetooth low energy, eGPS and FM Tx and Rx technologies into BlueCore7 alongside an enhanced Bluetooth v2.1 + EDR radio which delivers +10dBm Tx and –91 dBm Rx. These enhancements help BlueCore7 to extend the overall range and across-body performance to provide better audio quality (think handset on one side of the body and headset on diagonally opposing ear). BlueCore7 includes CSR’s proprietary AuriStream voice CODEC, which produces the quality of a fixed line call, when using a Bluetooth connection, and is capable of a 30% reduction in power consumption. |  |
Inbuilt speaker drivers also allow users to connect headphones directly to the device.
Bluetooth is the most successful short-range wireless technology in use today, with attach rates in handsets expected to reach 55-60% in 2008. By integrating more wireless technologies into its Bluetooth subsystem, CSR delivers a powerful connectivity centre that enables designers to increase functionality of their end products without impacting the size or the bill of materials (BOM). CSR’s wireless connectivity value centre within a handset is the ideal place to integrate new technologies including GPS and FM transmit. BlueCore7 is a low cost robust solution to allow designers to incorporate must-have functionality quickly and easily, allowing faster times to market.
BlueCore7 is available in QFN and WLCSP packaging and will be in volume production from Q4 2008.
