CSR upgrades Bluetooth chip range

There are three chips in the range – BC6130, BC6140 and BC6150 – catering between them for a range of price points and features. Compatible with the v2.1+EDR Bluetooth specification, the devices boast advanced features including CSR's Proximity Pairing technology, a faster user interface, Handsfree Profile (HFP) multipoint and programmable audio prompts. The BC6140 and BC6150 support CSR's fifth generation Clear Voice Capture (CVC) speech processing system; described as the first such system to feature both far end and near end audio improvements. "Our BlueCore ROM devices provide the most comprehensive range of single chip solutions for mono headsets," said Anthony Murray, senior vice president of CSR's Audio and Connectivity Business Unit. "Not only do they cover every segment of the market, but they include new features such as Proximity Pairing and CVC 5.0." According to CSR, the range makes it easier for designers to create innovative, differentiated and low power products. Each chip in the range is pin compatible with a previous CSR Bluetooth headset ROM chip, providing an easy upgrade path. All three chips feature CSR's Proximity Pairing technology. This allows the headset to find, and then pair with, the Bluetooth source device that is physically closest to it. The headset initiates the pairing activity and the user simply has to accept the incoming invitation on the source device. CVC 5.0 provides 'state of the art' audio enhancements and noise suppression to the near and far end, as well as providing packet loss and bit error concealment.
