Synaptics SYN4382 is a triple combo SoC with Wi-Fi 5/6E, Bluetooth 5.3, and IEEE 802.15.4 (Zigbee/Thread/Matter) radios, and manufactured with a 16nm process to lower power consumption for IoT and multimedia applications.
The chip can deliver up to 1,200 Mbps WiFi throughput, supports dual-band (RSDB) 2.4 and 5 or 6/6E GHz operation to combine the links at different frequencies, as well as features such as LE Audio for multiple concurrent audio streams in a multi-device environment.
Synaptics SYN4382 key features:
- Triband 2×2 Wi-Fi 6E (802.11ax) with 1200 Mbps throughput, RSDB, and support for legacy 802.11a/b/g/n/ac WiFi
- Bluetooth 5.3 with LE Audio, Channel Sounding (HADM = High Accuracy Distance Measurement) for accurate positioning
- 802.15.4 radio for Thread and Zigbee
- Matter interoperability
- Smart Co-Ex for coexistence in the 2.4 GHz band
- Multipoint external coexistence interface for LTE, GPS
- On-chip power amplifiers (PAs) and low-noise amplifiers (LNAs) with support for external PAs and LNAs
- Process – 16 nm process
We don’t have much more information, except the SYN4382 is expected to be found in automotive infotainment systems, OTT TV boxes and set-top-boxes, and TV/home theater audio systems. It’s an update to the SYN4381 limited to 600 Mbps throughput and Bluetooth 5.2 for which we have a block diagram.
[Update: Synaptics emailed us the block diagram SYN4382 block diagram as well
So the SYN4381/SYN4382 will have to be connected to a host processor via USB, SDIO, or PCIe x1 Gen 2 interfaces, and the chips are supported by Synaptics’ SynFi software tools.
The SYN4382 Triple Combo SoC is available now, and so is a “Triple Combo EVK”, but few details have been made public on the product page. The press release may have a few extra tidbits of information.
