Cambridge Silicon Radio has launched two new BlueCore2 Bluetooth solution devices that are claimed to be the smallest solution to date and eliminate the need for external nonvolatile memory.

Aimed at mobile handset applications, the BlueCore2-ROM reduces external components by integrating loop filter components and a linear voltage regulator into a 6-by-6mm BGA package.

The BlueCore2-Audio is designed for the headset and audio markets, and is essentially the same as the BlueCore2-ROM except for an additional 15-bit audio CODEC, microphone amplifiers, and speaker drivers.

"BlueCore2-ROM and Audio validates the idea that combining both RF and baseband on the same silicon gives lower overall costs. The Bluetooth standard has now reached an adequate level of maturity, that it is no longer a risk to place the code into ROM", said James Collier, technical director and co-founder of CSR.

Further, the products are qualified for operations between -400C to 1050C, making them suitable for all market segment requirements.
