CSR plc has released what it says is the first auto-grade chipset to combine WiFi and Bluetooth v4.0 connectivity with audio capabilities. The CSRC9300 will enable car manufacturers to deliver future connected car applications such as Miracast over 5Ghz and keyless entry using Bluetooth v4.0, stated the company.

According to the firm, the solution will provide next-generation WiFi for high-bandwidth applications, Bluetooth v4.0 Smart Ready for the low-power connectivity ecosystem and complementary audio, including aptX for high-fidelity wireless streaming.

The CSRC9300 enables next-generation 5Ghz WiFi connectivity with the 802.11a standard, which is set to support a number of applications for the car including in-vehicle video streaming. By moving high bandwidth demanding applications to the 5Ghz frequency, designers can avoid congestion on the 2.4Ghz frequency in the vehicle which is also used for Bluetooth and Bluetooth Smart Ready communications. The chipset will also support the latest WiFi features, including WiFi direct and its services, which will enable more seamless WiFi connectivity between cars and the latest smartphones on the market, detailed CSR.

The chipset also contains Bluetooth v4.0 support that enables low-power connectivity and basic data transfer for applications previously limited by the power consumption, size constraints and complexity of other wireless standards. By including Bluetooth v4.0, the chipset will enable applications such as proximity and keyless entry applications. It will also allow consumers to securely connect to their cars, so they can have data such as lock/unlock status sent to their Bluetooth Smart Ready enabled smartphones.

In addition, the chipset incorporates audio offloading capabilities such as on-chip support for wideband speech codec processing, and Advanced Audio Distribution Profile (A2DP) decoding for high-fidelity wireless audio. CSRC9300 will also include CSR’s aptX audio codec to ensure consumers can stream CD-quality audio over Bluetooth from aptX-enabled smartphones such as the Samsung Galaxy S4.

By combining and optimizing both software and hardware elements of the chipset, CSR has reduced engineering efforts for companies looking to integrate the device into next-generation designs. Existing customers can also reuse their software investment in existing CSR Bluetooth and WiFi solutions, while migrating to the new solution, to enhance their existing designs. The hardware components required to power the CSRC9300 have also been minimized, providing significant cost savings. CSRC9300 also offers a single, flexible solution for designers with a Bluetooth and WiFi capable device, as well as a WiFi only variant in the same automotive grade package.

Engineering samples for the CSRC9300 are available.
