General Description
BlueCore®
CSR's
CSR8630 QFN is a single-chip
Bluetooth ROM audio solution for Bluetooth audio sink
and music streaming applications.
The QFN package integrates an ultra-low power DSP
and application processor with embedded ROM
memory, a high-performance stereo codec, a power
management subsystem, LED drivers and a
comprehensive set of analogue and digital peripherals
in a single-chip, ensuring minimum system and
production costs.
The CSR configuration tools provide manufacturers
flexibility to customise from an extensive range of
human machine interface settings, define PIO functions,
associate device control with different button
configuration and define unique LED patterns with user
actions, system states and systems.

Applications
Bluetooth stereo speakers
A2DP audio sink (including multipoint) for music
streaming
The battery charger architecture enables the CSR8630
QFN to independently operate from the charger supply,
ensuring dependable operation for all battery
conditions.
The enhanced Kalimba DSP coprocessor with 80MIPS
supports enhanced audio and DSP applications.
The integrated audio codec supports stereo input and
output, as well as a variety of audio standards.
Full AVRCP v1.4 support enables music play / pause
and forward / rewind functionality with assured IOP
coverage.
Support for simple Android-based Apps enables options
to differentiate user applications, e.g. battery status
monitoring.
