BlueCore Player is a Bluetooth-enabled MP3 player design with an electronic bill of materials (eBOM) of less than $10. It enables sharing music by streaming to two headsets simultaneously, and enables direct streaming of MP3 files to reduce power consumption. BlueCore Player is based on CSR’s BlueCore5-Multimedia chip with embedded RISC & DSP coprocessor, and 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 an MP3 player in a compact form factor less than 45x60 mm. It 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.

BlueCore5-Multimedia External is Bluetooth v2.1 ready and supports v2.0+EDR of the Bluetooth specification.
