CSR8670 WLCSP
Development Kit
Product Overview
The BlueCore® CSR8670 WLCSP development kit contains everything
for required for rapid evaluation and development of Bluetooth stereo and
mono audio applications. It is based on CSR’s latest generation single
chip Bluetooth audio solution: BlueCore® CSR8670.
The BlueCore® CSR8670™ WLCSP consumer audio platform for wired
and wireless applications integrates an ultra-low-power DSP and
application processor with embedded flash memory, a high-performance
stereo codec, a power management subsystem, LED and LCD drivers
and capacitive touch sensor inputs in a SOC IC. The dual-core
architecture with flash memory enables manufacturers to easily
differentiate
their products with new features without extending development cycles.
Along with CSR’s Audio Development Kit (ADK) software suite and the
CSR headset configuration tools, the development kit provides a very
flexible and powerful development platform for designing advanced, highquality, Bluetooth stereo and mono products based on the BlueCore®
CSR8670 single chip Bluetooth audio solution.
