Nordic Semiconductor nRF7002 dual-band WiFi 6 companion chip is the first WiFi chip from the company and is designed to add Wi-Fi connectivity to solutions based on nRF52840 and nRF5340 wireless SoCs, and nRF9160 cellular IoT SiP, as well as non-Nordic host microcontrollers.
The nRF7002 also adds Wi-Fi-based locationing (SSID sniffing of local Wi-Fi hubs) when used alongside Nordic’s existing products, and the launch means Nordic is now one of the rare companies offering chips for Bluetooth, 802.15.4 (Matter/Thread), Wi-Fi, and cellular IoT (NB-IoT, LTE Cat M). This was made possible with the acquisition of the development team, core Wi-Fi expertise, and Wi-Fi IP assets of Imagination Technologies Group in 2020.
Nordic Semi nRF7002 key features specifications:
- Complies with 802.11a/b/g/n/ac/ax
- 2.4 GHz and 5 GHz dual-band
- Wi-Fi 6 Station (STA)
- 1 Spatial Stream (SS)
- 20 MHz channel bandwidth
- 64 QAM (MCS7), 86 Mbps PHY throughput
- OFDMA (Downlink and Uplink)
- BSS coloring
- Co-existence interfaces, including Bluetooth LE
- Low-power and secure Wi-Fi for the IoT
- Target Wake Time (TWT)
- Host interface – SPI / QSPI
- Package – 6×6 mm QFN
The nRF7002 will be supported in the nRF Connect SDK, but that’s about all we know so far, as technical documentation and information about development kits have not been made public just yet. [Update: there’s actually documentation for the nRF7002-PDK, a board that combines nRF7002 with nRF5340 dual-core Cortex-M33 SoC. It’s not just linked from the product page just yet
Nordic Semi says the nRF7002 is already sampling now, and that interested customers should contact their local Nordic distributor for more details. You may be able to find a few more details on the product page or press release. The company will also showcase the nRF7002 in the upcoming Nordic Tech Tours taking place in North America and EMEA.
