Synaptics Launches Industry’s First Matter-Compliant Triple

SAN JOSE, Calif., Feb. 02 2, 2022 (GLOBE NEWSWIRE) — Synaptics® Incorporated (Nasdaq: SYNA) today announced the Triple Combo SYN4381 system-on-chip (SoC), the first to combine Wi-Fi 6/6E (802.11 ax with extended 6 GHz), Bluetooth® 5.2 (BT 5.2) with BLE Audio and High Accuracy Distance Measurement (HADM), and IEEE 802.15.4 with integrated support for Thread protocol and Matter application layer. The SoC and its supporting SynFiMT simplifies product development and reduces time to market, while accelerating the transition to seamless, secure and scalable connectivity between devices on heterogeneous Internet of Things (IoT) networks, regardless of platform, OEM or brand.

The typical smart home includes devices from multiple vendors with a variety of wireless interfaces and communication protocols. Device developers choose them for their suitability for specific functions, such as high-speed video or data (Wi-Fi), low-power sensor and control networks (802.15.4 with Zigbee or Thread) , or point-to-point communication for audio or file transfers (Bluetooth). The fact that these devices cannot interoperate is a constant source of frustration for end users, as it prevents them from realizing the full promise of a fully interactive smart home.

Instead of forcing developers and end users to choose between different RF interfaces or “walled garden” branded ecosystems, the SYNA4381 Triple Combo combines the three main interfaces and adds support for Matter. Matter is a standards-based unified communications protocol that, when deployed across all devices, enables secure interoperability regardless of the network the devices use. For example, the user can control blinds connected to a Zigbee network using commands given to a smart speaker running on the home Wi-Fi network.

Developers can now focus on their application rather than the complexities of cross-platform communication, simplifying development and speeding devices to market. End users, on the other hand, benefit from simplified setup and seamless control of all their smart home devices.

The SYN4381 delivers industry-leading Wi-Fi performance, with Wi-Fi 6E data rates up to 600 Mbps, along with transmit power and receive sensitivity that together enable throughput. high sustained over an extended range for full house coverage. In addition to proximity sensing using HADM, its full-featured dual-mode BT 5.2 radio supports the best Wi-Fi/Bluetooth/802.15.4 coexistence performance. Built-in support for the Thread networking protocol allows devices using the SYN4381 to connect to a secure, low-power smart home mesh network, while acting as a Thread router node. The SynFi wireless stack allows developers to use the same software on Triple Combos and future Synaptics Wi-Fi/BLE/802.15.4 chipsets, further reducing overall time to market.

Triple Combo meets growing market demand
According to market research firm IoT Analytics, the number of connected IoT devices is expected to reach 12.3 billion by the end of 2021 and 27 billion by 2025.1 The growing trend of work from anywhere (WFA) as well as the need for devices from multiple OEMs and brands to be interoperable to reduce user frustration is fueling the need for multi-standard connectivity.

“Synaptics is today a recognized leader in combined wireless solutions with excellent traction with our customers for a wide range of applications such as media streaming, gaming, surveillance cameras and drones, to name a few. name just a few,” said Alex Chou, senior vice president. and General Manager, Wireless Connectivity Division at Synaptics. “The Triple Combo is the next logical step towards a seamless user experience, while delivering industry-leading performance on three of the most popular and widely used networking technologies in the smart home. We expect the market to quickly begin the transition to Triple Combos with launches expected by the end of 2022.”
