Synaptics SYN43711 WiFi 6E & Bluetooth 5.3 chipset targets IoT devices, video streaming, robotics

Synaptics SYN43711 is a new WiFi 6E and Bluetooth 5.3 “SoC” designed for “IoT applications” such as high-end home appliances with video streaming capabilities, surveillance cameras, robots, and other secure smart consumer, industrial, and enterprise systems.

It’s a more cost-effective version of the company’s SYN4382 SoC that supports 1,200 Mbps 2×2 MIMO Wi-Fi 6E, Bluetooth 5.3, and 802.15.4 connectivity. Designed for small form factor devices, the new SYN43711 tri-band chipset supports 600 Mbps WiFI 6E, Wi-Fi Sensing (human presence detection), and Bluetooth 5.3 with LE Audio for multiple concurrent Bluetooth connections and audio streams, including Auracast audio sharing.

SYN43711 key features and specifications:

Wireless
- Tri-band (2.4, 5, 6 GHz) Wi-Fi 4, 5, 6, 6E up to 600 Mbps (1×1 antenna arrangement)
- Bluetooth 5.3 LE with LE Audio support
- Integrated PAs and LNAs (external PA and LNA optional) with high transmit (Tx) power level and receive (Rx) sensitivity
- Synaptics Smart Co-Ex for coexistence of Wi-Fi and Bluetooth radios in the 2.4 GHz band.
Host interfaces
- WiFI – PCIe Gen 1 and SDIO 3.0
- Bluetooth – UART, I2S, PCM
Debugging – JTAG/SWD (but note there’s no user-programmable core, so likely for internal debugging at Synaptics)
Misc – GPIO for LEDs, 16 Kbit OTP flash
Power Management – Integrated PMU
Dimensions – 5.41 x 4.24 x 0.51mm (WLBGA packages: standard and plated-through-hole (PTH))

Synaptics called the SYN43711 an SoC (System-on-Chip), and while many people think of SoC as a chip with a user-programmable core, the company has a different definition as we confirmed with them when the SYN4382 “SoC” was released. So the SYN43711 is actually a chipset that is connected to a host microcontroller or application processors via several interfaces to control WiFi and Bluetooth. There should be one or more Arm cores, explaining why there’s a JTAG/SWD interface, but only for Wi-Fi and Bluetooth data and protocol processing.

There’s very little information available on the product page. Synaptics says the SYN43711 is sampling to key customers now and mass production is scheduled to ramp up in Q1 2024. A few more details may also be found in the press release.
