SYN4383 "Triple Combo 3" Wi-Fi, Bluetooth, IEEE 802.15.4 SoC

The Synaptics SYN4383 integrates Wi-Fi® 6/6E, Bluetooth® 5.4, and IEEE 802.15.4 radios on a single state-of-theart system on chip (SoC) to reduce the space, cost, power, complexity, and time to market of wirelessly enabled IoT devices.

With applications ranging from multimedia streaming for the smart home to automotive entertainment, security, and the smart factory, the SYN4383 is Matter compliant for secure, seamless interoperability in a heterogeneous, multi-platform wireless environment. The Wi-Fi radio is IEEE 802.11ax compliant with legacy support for 802.11a/b/ g/n, has a 2x2 antenna arrangement for a throughput of up to 1200 Mbps, and features real simultaneous dual-band (RSDB) capability to allow the 2.4 GHz and either the 5 GHz or 6 GHz radios to connect and stream multimedia content at the same time for optimum performance and more robust connectivity. The Bluetooth 5.4 (6.0 compliant) radio features LE Audio for multiple concurrent Bluetooth audio streaming connections, as well as Bluetooth Channel Sounding for accurate positioning. Built-in support for the Thread networking protocol allows devices using the SYN4383 to connect to a smart home’s secure, low-power mesh network while acting as a Thread Router node, including advanced mesh networking and security features.
