CSR Delivers Connectivity for Samsung's Bluetooth MP3 Player

CSR says that Samsung's YP-T9B portable media player contains CSR's BlueCore technology for Bluetooth. The new Samsung's device is available worldwide already and it is the first of Samsung's line of MP3 players to feature integrated Bluetooth connectivity. Powered by CSR's BlueCore3-ROM with embedded BlueCore Host Software, the Samsung YP-T9B player allows users to listen to high quality audio without wires as well as streaming music to Bluetooth enabled speakers.

Samsung's decision to implement CSR technology into the small T9 media player demonstrates BlueCore's compact design and easy integration. At just 0.43 inches thick and weighing a mere 1.7 ounces, the YP-T9B is packed with a variety of multimedia features such as music playback, FM radio, voice recording, and movie capabilities. With integrated Bluetooth connectivity, users can wirelessly transfer files from PCs to the T9 as well as listen to streaming music and accept mobile phone calls using Bluetooth headphones. The in-built music player supports MP3, WMA and OGG music formats with files being stored on up to 4GB of internal memory. A fully charged YP-T9B achieves up to 30 hours of music play back or 7 hours of video playback with CSR's BlueCore3-ROM chip-scale package requiring minimal battery power thanks to the use of BlueCore Host Software.

BlueCore3-ROM's complete single-chip solution with on-chip microcontroller and 4Mbits ROM enables device manufacturers to easily incorporate robust Bluetooth connectivity into their handsets. The design of CSR's silicon also reduces the number of external components required for Bluetooth implementation, ensuring that as well as minimising production costs and time to market, Bluetooth connectivity can be designed into the smallest of devices. CSR has also implemented advanced co-existence techniques such as adaptive frequency hopping to ensure that the Bluetooth connection is robust and does not interfere with other 2.4GHz radios such as WiFi.

CSR's BlueCore Host Software, which is optimised for BlueCore silicon, provides a complete system software solution for embedded BlueCore applications. BCHS ensures that existing processing power already in the digital audio player can be utilised for Bluetooth, thus providing the most cost effective way to implement Bluetooth in today's consumer products. BCHS also reduces Bluetooth power consumption by implementing all possible low power modes such as deep sleep mode. This allows the BlueCore silicon to effectively shut down the Bluetooth radio.
