CSR has introduced an advanced series of ROM-based chips for the Bluetooth mono headset market.

Marketed under the brand-name BlueCore, CSR's new series of mono ROM devices consists of three chipsBC6130, BC6140 and BC6150which offer a wide range of price points from low cost to mid-level.

Fully compatible with v2.1+EDR of the Bluetooth specification, CSR's ROM devices offer advanced new features, including CSR's own Proximity Pairing technology, a faster user interface, Handsfree Profile (HFP) multipoint and programmable audio prompts. Both BC6140 and BC6150 also support CSR's new fifth-generation Clear Voice Capture (CVC) speech processing system, featuring both far-end and new near-end audio enhancements.

The BC6130 and BC6150 are pin compatible with previous CSR Bluetooth headset ROM chips, providing an easy upgrade path for existing customers. BC6130 is pin compatible with BlueVox2 and includes HFP multipoint, which allows multiple simultaneous connections between a Bluetooth headset and two devices. It also features programmable audio prompts that can be used to help guide users through pairing or for custom audio tones.

BC6140 has all of the features of BC6130 but also includes CSR's high performance 24bit, 64 MIPS on-chip DSP and supports CSR's new CVC 5.0. CVC 5.0 provides high audio quality in noisy and harsh acoustic environments through a collection of advanced algorithms for speech on the transmit and receive signal paths. Packet loss and bit error concealment is an advanced audio feature that restores audio quality in difficult RF environments.

CSR's BC6150 is a DSP ROM solution for the mid range headset market that supports both single and dual-microphone CVC 5.0. Pin compatible with CSR's BlueVox DSP, BC6150 boasts high noise reduction to allow users to be heard clearly in a noisy environment.

BlueCore mono ROM headset chips will start sampling in Q2 09. The new features are also available now as a software update on BlueCore5-Multimedia, CSR's single-chip Bluetooth multimedia silicon for high-end mono headsets.
