Designed with proven technology to enable innovation and feature differentiation at the premium end of the Bluetooth speaker and headphone markets. It has 4 times more DSP processing power than the previous premium Bluetooth SoC CSR8675 and includes advanced features all on a single-chip platform, supporting development of portable wireless speakers and headphones with superior audio quality, voice control, far-field echo cancellation, sensor processing and audio post processing. CSRA68100 offers the freedom to innovate, with a dedicated customer application processor sub-system, next generation ADK software and enhanced development tools, including a new ability for the DSP to dynamically reconfigure at runtime.
CSRA86100 is no longer for sale. If you need a similar product, Qualcomm recommends CSRA86105.
CSRA68100, Qualcomm aptX, Qualcomm Kalimba and Qualcomm Kymera are products of Qualcomm Technologies, Inc., and/or its subsidiaries.
