CSR delivers reference design for Bluetooth-enabled MP3 player

CSR Ltd.'s BlueCore Player boasts an electronic bill of materials of less than $10, which the company claims sets a new benchmark for Bluetooth-enabled MP3 player designs.

BlueCore Player can stream music to two headsets simultaneously. It also enables direct streaming of MP3 files to reduce power consumption. It is based on CSR's BlueCore5-Multimedia chip with an embedded DSP coprocessor and a 16-bit stereo codec to ensure high quality stereo sound.

The BlueCore Player reference design includes all the circuit diagrams, software, Gerber files, and hardware needed for a superior MP3 player in a compact form factor less than 45x60 mm.

The player supports the Bluetooth Audio Video Remote Control Profile (AVRCP) to control stop and start playback and volume control, and the Advanced Audio Distribution Profile (A2DP) for high quality audio streaming.

Also included in the eBOM is an OLED color display, supporting both Asian and Arabic fonts, a lithium battery with more than 14 hours of playback, an on-chip charger and a mini-USB charger connector.

CSR's BlueCore Player also contains an audio navigation menu enabling the user to run through the tracks, artist names and playback modes without the need for a screen, thus reducing the BOM costs further. This function utilizes the latest Text to Speech (TTS) technology and runs on BlueCore's DSP.
