Ideal for entry-level to mid-range wireless audio products
The CSR8640 SoC has a reduced feature set supporting the essential features expected from Bluetooth audio products while providing cost efficiency for entry-level products.
Integrated single-chip solution for smaller designs
Application processor, Bluetooth and Bluetooth low energy radios, DSP and memory integrated into a single SoC helps reduce system complexity and eBOM while supporting small form factor designs.
No software development required
Pre-loaded Bluetooth and audio applications allow manufacturers to develop end-products without writing code, while customization tools support quick modification of device behaviour and user interface.
cVc 6th generation 2-mic audio technology
cVc technology is a suite of algorithms designed to work on the transmit and receive path of voice calls to deliver optimum voice quality on Bluetooth headsets, handsets, hands-free devices, and automotive.
