CSR unveils next-generation, consumer wireless audio platform

The CSR8600 consumer audio platform provides the foundation for a family of highly integrated single-chip products CSR will introduce to meet the needs of a broad and exciting range of connected consumer audio products. From next-generation TVs, connected home entertainment systems and wired and wireless speakers to tablets, PCs and other mobile connectivity applications, the CSR8600 platform will be able to deliver a rich audio experience along with advanced Bluetooth and Bluetooth low energy connectivity. The CSR 8600’s tiny size, energy efficiency and other features make it ideal for use in a variety of compact portable and wearable products that offer longer battery life, including smart remote controllers, wireless headsets and headphones and portable media players equipped with wireless heart-rate monitor, foot-pod and other sensors.

“The CSR8600 family of products will enable us to extend our current leadership position in the consumer wireless audio market, where audio performance, form factor and a rich, consumer-centric feature set are among the key success factors,” said Anthony Murray, Senior Vice President of CSR’s Audio and Consumer Business Unit. “With the evolution of the connected home and the explosive growth in connected personal entertainment and information systems, there is a tremendous need for a highly integrated, wireless consumer audio solution like the CSR8600 platform, and no one else offers this with the level of flexibility and capability that CSR does in a single-chip solution.”

“Bluetooth technology has been hugely successful, having largely replaced wired headsets in a number of markets, and now we believe the outlook for high-quality Bluetooth stereo is positive as it moves into new growth areas such as portable media players, home entertainment systems, wireless speakers, tablet and mobile device accessories, wearable audio and other connected lifestyle products,” said Alex West, Director of Connectivity, IMS Research. “With flash memory, touch sensors and many other peripheral functions and components all integrated into a compact, efficient, high-performance System-on-a-Chip platform like the CSR8600, manufacturers will be able to create a variety of innovative products that provide consumers with a more compelling user experience.”

The CSR8600 platform introduces a more powerful audio processing engine with a flexible memory architecture for internal flash memory or ROM, as well as external serial flash, providing a platform that supports the development and deployment of a variety of high-quality audio algorithms for enhanced audio quality. These include CSR’s aptX™ high-fidelity, low-latency audio technology for outstanding stereo audio over Bluetooth connectivity to wireless speakers or headphones while ensuring accurate lip-sync, as well as CSR’s Clear Voice Capture (CVC®) technology for acoustic echo and noise cancellation, enabling the CSR 8600 platform to provide high-quality speakerphone functionality in televisions, tablets and PCs and other consumer products.

The CSR 8600 platform incorporates CSR’s industry leading Bluetooth technologies, including support for Bluetooth 3.0 to enable wireless streaming of high-fidelity stereo audio in home entertainment systems, TVs and other connected home applications. The CSR8600 also supports Bluetooth low energy, unlocking the potential of this new standard, and can be used in conjunction with CSR’s family of µEnergy™ Bluetooth low energy solutions to enable ultra-low-power connectivity and simple data transfer for wireless accessories, including 3D glasses, remote controllers and other applications previously limited by the power consumption, size constraints and complexity of other wireless standards.

Power consumption in the CSR8600 platform is significantly reduced through a combination of its ultra-low-power DSP architecture, new power supply subsystem, an efficient memory system, a reduction in process node geometry and by tailoring device firmware and software during critical modes of operation. The platform integrates multiple high-frequency switching power supplies that are very power efficient, low drop-out regulators and a new battery charger architecture with instant-on and fast charging capabilities, as well as support for USB charging.

With leading-edge IC packaging that is nearly half the size of previous-generation devices and a highly integrated design that greatly reduces overall BOM count and PCB size, the CSR8600 platform enables OEMs to create consumer electronics products with more compact and aesthetically pleasing designs. The CSR8600 platform includes a cornucopia of integrated peripheral and I/O components, including an internal balun for direct antenna connection, embedded flash memory or ROM, a high-performance audio codec, support for GPIO, UART, USB, SPI and I2C digital I/O, digital and analogue microphone inputs, LED and LCD drivers and capacitive touch sensors.

At the software application level, the CSR8600 platform is backward compatible with CSR’s popular BlueCore5-Multimedia™ platform, enabling easy migration of a broad range of CSR eXtension partner solutions, and facilitating the rapid time to market of a broad portfolio of CE products.

The first product(s) based on the CSR8600 platform is already being sampled to lead customers and will be in production by mid 2011. Please contact your CSR representative for further information on specific CSR products based on the CSR8600 wireless consumer audio platform.
