Synaptics Launches Triple Combo 16nm Ultra-Low-Power SoC to Drive New Automotive and Multimedia Use Cases

Offering enhanced connectivity and streaming features, Synaptics latest SYN4382 Triple Combo offers Matter-compliant Wi-Fi 2.4/5/6/6E, Bluetooth 5.3, and IEEE 802.15.4 wireless, with the ability for simultaneous operation of two radios and multiple Bluetooth channels to stream multimedia content. This state-of-the-art system-on-chip enables new exciting audio and video experiences, while lowering power consumption, cost, and system complexity.
 
Building upon the original Triple Combo 16nm SYN4381 platform — the first to integrate Wi-Fi 5/6E, Bluetooth 5.3 (BT 5.3), and IEEE 802.15.4/Thread radios — the ultra-low-power SYN4382 features a doubling of Wi-Fi throughput to 1200 Mbps, the addition of another discrete radio channel for real-time simultaneous dual-band (RSDB) 2.4 and 5 or 6/6E GHz operation for robust, high-speed Wi-Fi connectivity, and LE Audio for multiple concurrent BT 5.3 audio streams in a multi-device environment.

The new SoC comes with built-in support for the Matter application layer to ensure interoperability of connected smart devices across heterogeneous wireless networks, as well as Synaptics’ own best-in-class, proprietary, Smart Co-Ex coexistence technology, to ensure a seamless multimedia wireless experience. Synaptics' Smart Co-Ex technology ensures best-in-class coexistence in the 2.4GHz band, with multipoint external coexistence interface for LTE and GPS.

"SYN4382 is the perfect solution for complex, streaming-intense applications such as advanced automotive infotainment units and high-end OTT and TV/home theater audio systems," says Brandon Bae, Sr. Director of Product Marketing at Synaptics. "For example, in a car, the first Wi-Fi 6E radio can act as a soft access point and stream multimedia content to a number of local in-car devices. The second radio, meanwhile, provides the ability to connect to a high-speed Wi-Fi network. At the same time, the SYN4382 is capable of using LE Audio to stream to multiple BT 5.3 devices, including rear entertainment systems." Along with reduced hardware complexity, the SYN4382 is supported by Synaptics’ Syn-Fi software tools to simplify product development and reduce time to market for increasingly advanced IoT devices that need to connect across heterogeneous IoT networks, regardless of platform or OEM. On-chip power amplifiers (PAs) and low-noise amplifiers (LNAs) also offer support for external PAs and LNAs to extend product design performance.

The new SoC integration uses a 16nm process node that allows ultra-low power operation and advanced integration for a smaller footprint, reduced complexity, and lower BOM. It features 2x2 Wi-Fi (2.4/5/6/6E GHz operation and legacy 802.11a/b/g/n/ac) with 1200 Mbps throughput for fast streaming and distribution of multimedia content, and RSDB capability that enables architectural flexibility to assign content to the most appropriate 2.4 and 5/6 GHz radio for optimum performance and robust connectivity. The Bluetooth 5.3 with LE Audio radio enables multiple concurrent BT 5.3 audio streams in a multi-device environment, supporting Bluetooth High Accuracy Distance Measurement (HADM) for accurate positioning. 

Integrated Thread/Zigbee support using IEEE 802.15.4-based standard enables cross-platform interoperability and ultra-low-power mesh networking and security features, including Matter interoperability and security support for a seamless user connectivity experience across heterogeneous networks.
