CSR has partnered with Cheertek to produce a reference design for a digital photo frame chipset with Bluetooth functionality. Cheertek has implemented CSR's BlueCore4-ROM, a complete Bluetooth system designed to ensure minimum time to market for OEMs. BlueCore4-ROM allows the frame to not only receive pictures but also to play audio streamed via Bluetooth, providing a richer experience for the consumer.

Along with BlueCore4-ROM, Cheertek has employed CSR's BCHS (BlueCore Host Software). This software offers OEMs a simple and complete Bluetooth solution designed for fastest time-to-market and lowest cost since it provides the upper layers of the Bluetooth protocol stack along with power-saving intelligence and a large library of Bluetooth profiles. BlueCore4-ROM is optimised for coexistence with other radios, and BCHS's simple yet powerful APIs make it possible for OEMs to develop a Bluetooth product without expert Bluetooth knowledge. CSR's hardware provides support for Bluetooth versions 1.2, 2.0+EDR and 2.1+EDR.

Frames based on Cheertek's design are able to receive pictures from mobile phones, PMPs, PCs and any other devices with appropriate Bluetooth functionality. Cheertek frames can also operate as mini entertainment devices, streaming audio from Bluetooth-enabled media devices and phones via built-in stereo speakers.

Besides BlueCore4-ROM, the Cheertek frame design utilises a RISC processor alongside its own CT956A chip. The design supports BIP, FTP and OPP Bluetooth profiles for photo transfer, A2DP and AVRCP for streaming and AVRCP for remote control functionality. "This design offers remarkably diverse functionality," said Tracy Hopkins, VP of consumer business unit at CSR. "The convenience factor will ensure that frames based on this design will sell well, as well as the audio capabilities. We believe that wireless functionality is going to be a huge market driver in the next generation of digital photo frames."

The Cheertek Development Kit will be available in February. It includes the software development environment and hardware development boards featuring CSR's BlueCore4-ROM Bluetooth chip and the CT956A chip.
