SYN4381 SoC from SYNAPTICS
New Triple Combo for Multi Standard Connectivity
SYNAPTICS has introduced the SYN4381, a triple combo system on chip (SoC) that is the first to combine WiFi 6/6E (802.11ax with extended 6 GHz operation), Bluetooth® 5.2 (BT 5.2) with BLE Audio and High Accuracy Distance Measurement (HADM) and IEEE 802.15.4 with built-in support for the Thread protocol and Matter application layer.
The SoC and supporting SynFiTM software simplify product development and shorten time-to-market. At the same time, they accelerate the transition to seamless, secure and scalable connectivity between devices in heterogeneous Internet-of-Things (IoT) networks, regardless of platform, OEM or brand.
Detailed Information
A typical Smart Home consists of devices from different manufacturers with a variety of wireless interfaces and communication protocols. Device designers select these based on their suitability for specific functions, such as high-speed video or data (WiFi), low-power sensor and control networks (802.15.4 with Zigbee or Thread), or point-to-point communications for audio or file transfers (Bluetooth). The inability of these devices to work together is a constant source of frustration for end users, as it prevents them from fully enjoying the promise of a seamlessly interactive Smart Home.
Rather than forcing developers and end users to choose between the various RF interfaces or "walled garden" brand ecosystems, the SYN4381 Triple Combo combines all three primary interfaces and adds support for Matter. Matter is a unified, standards-based communications protocol that, once deployed on all devices, enables secure interoperability - regardless of which network the devices use. For example, users can control blinds connected to a Zigbee network via commands given to a smart speaker running on the home's WiFi network.
Developers can now focus on their application instead of dealing with the intricacies of cross-platform communication, simplifying development and speeding device time to market. For their part, end users get simplified setup and seamless control of all their Smart Home devices.
The SYN4381 offers industry-leading WiFi performance with WiFi 6E data rates of up to 600 Mbps, as well as transmit power and receive sensitivity that combine to provide sustained high throughput over a long range for full home coverage. In addition to proximity detection using HADM, the full-featured dual-mode BT 5.2 radio supports best-in-class WiFi/Bluetooth/802.15.4 coexistence performance, and built-in support for the Thread networking protocol allows devices using the SYN4381 to connect to a Smart Home's secure, low-power mesh network while acting as a threaded router node. The SynFi wireless stack allows developers to use the same software for Triple Combos and future Synaptics WiFi/BLE/802.15.4 chipsets, further reducing time to market.
