General Description
BlueCore^® CSR8620™ BGA is a product from CSR's
Connectivity Centre. It is a single-chip radio and
baseband IC for Bluetooth 2.4GHz systems.
The integrated peripherals reduce the number of
external components required, including no
requirement for external codec, battery charger,
SMPS, LDOs, balun or external program memory,
ensuring minimum production costs.
The battery charger architecture enables the
CSR8620 BGA to independently operate from the
charger supply, ensuring dependable operation for all
battery conditions.
Applications
■ _{2-mic mono headset}
■ _{Support for smartphone/tablet applications}
The enhanced Kalimba DSP coprocessor with
80MIPS supports enhanced audio and DSP
applications.
The integrated audio codec supports 2 microphone
inputs and mono output, as well as a variety of audio
standards.
