CSR8350™

CSR8350™ is a Bluetooth® v4.1 single-chip radio and baseband IC with advanced audio capabilities for Bluetooth enabled car audio systems, in-vehicle navigation and PND.

CSR8350’s dual-mode radio enables it to connect to the billions of Bluetooth products already on the market, as well as a new generation of Bluetooth low energy devices.  A powerful DSP provides support for advanced audio processing, including HD quality hands-free telephony, streaming audio, and optionally aptX® decoding and cVc® echo cancellation.  Integrated peripherals reduce the number of external components required, including external codec, SMPS, LDOs, balun or program memory, ensuring minimum production costs.

CSR8350 supports CSR Wake-on Smart™, enabling the host CPU to be powered down and reducing energy consumption for Bluetooth Smart use cases. When used with CSR Synergy® host software, the CSR8350 provides a system fully qualified to the Bluetooth v4.1 specification for data and voice communications.
