TL;DR
Nordic Semiconductor has introduced its nRF71 system-on-chip family, combining Wi-Fi, Bluetooth LE, Thread and edge-AI processing for connected devices. The company says the chips use up to 20 times less standby power than its nRF70 series; they are sampling with selected customers. Nordic also plans license-exempt Sub-GHz products, but has not announced models or confirmed Thread Sub-GHz support.
Nordic Semiconductor has introduced its nRF71 chip family, combining Wi-Fi, Bluetooth Low Energy, Thread and edge-AI processing in a system-on-chip aimed at connected devices. The announcement expands Nordic’s wireless offering beyond its established Bluetooth and Thread products; the company also says it is developing license-exempt Sub-GHz solutions, though it has not yet detailed the hardware.

The nRF71 family has two announced versions: the nRF7120, with dual-band Wi-Fi 6, and the nRF7120E, with tri-band Wi-Fi 6E. Both have 4MB of non-volatile memory and 1MB of RAM. Unlike Nordic’s earlier nRF70 Wi-Fi companion chips, the new SoCs combine connectivity and application processing, which may reduce the need for separate components in a device.
Nordic says the chips deliver up to 20 times lower standby power consumption than its current nRF70 series. That comparison is the company’s claim; the supplied announcement does not provide a test method or operating conditions. The chips also have two independent radios, which Nordic says can support simultaneous Wi-Fi and Thread or Bluetooth LE reception.
The SoCs include Nordic’s Axon neural processing unit for on-device machine-learning tasks such as sound recognition, anomaly detection and image classification. Nordic says supported models can run 10 to 17 times faster than on its 256MHz Arm Cortex-M33 processor alone. The nRF71 is sampling with selected customers, and Nordic is preparing a module based on the chips.
More Options for Connected Devices
By combining several radios and application processing in one chip, the nRF71 could give device makers another way to build products that need more than one type of wireless connection. The company’s stated standby-power reduction, if borne out in real products and under comparable conditions, could make Wi-Fi a more practical option for some battery-powered devices. Actual battery life will still depend on the device, network use and software.
Separate radios may also help designs that need to maintain connections across networks, such as bridges or border routers. The integrated AI hardware could let some supported recognition tasks run on the device rather than relying on a remote service. Those are potential uses, not confirmed performance results for finished products. The planned Sub-GHz line could address a different need: longer-range connectivity for metering, tracking and building systems.

Nordic Broadens Its Wireless Portfolio
Nordic is a supplier of Bluetooth and Thread chips used in connected products, including devices built for the Matter-over-Thread ecosystem. The nRF71 announcement extends its portfolio toward Wi-Fi, while the planned Sub-GHz work targets applications where range or signal penetration is a priority. The shift reflects competition among chipmakers to offer manufacturers more choices across wireless standards rather than focusing on a single connectivity category.
The source report points to Silicon Labs’ low-power Wi-Fi 6 platform and Espressif’s expansion into Zigbee and Thread as examples of that broader market movement. Meanwhile, the Thread Group has approved work to extend Thread into Sub-GHz spectrum. That standard remains in development; it is separate from Nordic’s announcement and does not establish that Nordic’s future products will support it.

Specifications Still To Come
Nordic has not published a detailed specification for the planned Sub-GHz products, identified chip models or provided a release schedule in the supplied material. It also has not confirmed whether those products will support the Thread Group’s developing Sub-GHz extension. The company says an early-adopter program is open to developers, but the source does not describe its terms or expected milestones.
For the nRF71, the announcement does not give pricing, general availability dates, detailed radio performance, or independent test results for the power and machine-learning comparisons. It is also not clear which specific devices or Matter products will adopt the chips. Sampling with selected customers is an early development stage, not confirmation of retail products.
Customer Sampling and Sub-GHz Plans
Nordic says it is sampling the nRF71 with selected customers and preparing a company-branded module based on the family. Further information on module specifications, availability and pricing will help manufacturers judge how the chips fit prospective designs. Developers can also follow the company’s early-adopter program for its planned Sub-GHz work.
The next material developments are likely to include fuller product specifications and details on timing. Until Nordic provides them, the reach, power use and standards support of its Sub-GHz products—and whether they will work with Thread Sub-GHz—remain open questions.
Key Questions
What are Nordic’s nRF71 chips?
The nRF71 family is a set of system-on-chips combining Wi-Fi, Bluetooth LE, Thread and edge-AI processing. Nordic has announced the nRF7120 with dual-band Wi-Fi 6 and the nRF7120E with tri-band Wi-Fi 6E.
Are the nRF71 chips available to buy?
Nordic says the chips are sampling with selected customers. The announcement does not state a general release date or pricing.
What does Nordic mean by lower standby power?
Nordic claims up to 20 times lower standby power consumption than its current nRF70 series. The supplied information does not include test conditions, so the figure should be read as a company comparison rather than an independently verified result.
Will Nordic’s Sub-GHz chips support Thread?
That has not been confirmed. Thread Sub-GHz is under development, and Nordic has not said whether its planned products will support it.
