Nordic nRF71 Explained: Wi-Fi 6 With 20x Lower Standby Power

Wi-Fi has long been the awkward guest in battery-powered designs: convenient, ubiquitous and hungry. Nordic Semiconductor's new nRF71 Series, announced on November 3, 2026, aims straight at that problem. The company claims up to 20 times lower standby power than its current nRF70 Series Wi-Fi products, with Wi-Fi 6, Bluetooth LE, Thread and an optional neural processing unit on a single chip.

• First parts: dual-band Wi-Fi 6 nRF7120 and tri-band Wi-Fi 6E nRF7120E, with the Axon NPU on the nRF7120E only.
• Memory: 1 MB of user-accessible RAM and 4 MB of on-chip non-volatile memory.
• Connected current: 14 µA at 2.4 GHz and 8 µA at 5 GHz on average at DTIM 10, per CNX Software's spec listing.
• Availability: sampling with selected customers now, with no general-availability date from Nordic.

nRF7120 and nRF7120E Specs

The silicon pairs an Arm Cortex-M33 with a RISC-V coprocessor, both running at up to 256 MHz. The coprocessor handles SoftPeripherals such as CAN 2.0B and SDIO. Other details from CNX Software's listing:

• Wi-Fi: 802.11ax with Target Wake Time, station and SoftAP roles, and up to +22 dBm transmit power.
• Bluetooth LE and Thread: a multiprotocol radio with up to +10 dBm transmit power and -99 dBm Bluetooth LE receive sensitivity.
• I/O: high-speed USB with integrated PHY, up to 65 GPIOs, plus SPI, UART, ADC and PDM interfaces.
• Security: TrustZone isolation, tamper detection and a CRACEN cryptographic accelerator, designed for PSA Certified Level 3.
• Package: a 4.9 x 4.6 mm WLCSP rated for -40 to +85°C.

Nordic's interesting architectural choice is two independent radios, with the 2.4 GHz multiprotocol radio coming from its nRF54 Series. Both can receive at once, so a device can hold its Wi-Fi connection while also listening for Bluetooth LE or Thread traffic. That suits a battery-powered Matter bridge or Thread border router, which are both applications Nordic names.

How Much Faster Is the Axon NPU?

Nordic says the Axon NPU runs machine learning models 10x to 17x faster than the 256 MHz Cortex-M33 alone. Its suggested workloads are keyword spotting, anomaly detection and image classification, so think small always-on models rather than language models. Parts without the NPU can still run ultra-small models built with Nordic's Neuton software on the processor, and over-the-air model updates go through nRF Cloud.

What Does 20x Lower Standby Power Mean in Practice?

Treat the headline as a vendor claim for now. The comparison is against Nordic's own nRF70 Series, and the announcement does not give test conditions or workloads. Independent measurements will have to wait until boards reach developers. The real-world gain will also depend heavily on how often a device wakes and what access point it talks to.

Even so, the direction is significant. If the numbers hold, Wi-Fi becomes plausible for products that previously had to choose Bluetooth or Thread for battery life, including smart locks, security panels and wearables. Nordic's own low-power parts already feature in our low-power wireless MCU guide, and the nRF71 extends that lineup upward.

When Can Developers Buy an nRF7120 Board?

Not imminently. CNX Software found the nRF7120-DK listed on DigiKey at $72.38 with a minimum order of 35 units and stock estimated for April 2027. Nordic is also working on its own module, and CNX reports that u-blox has listed an ALMA-W1 module based on these chips, still marked as in development. Both nRF7120 variants are already supported in the nRF Connect SDK, so software teams can begin reading up before the hardware is easy to get.

Nordic plans to show the series at Electronica. I will be most interested in standby current traces from independent testers. For more boards and modules worth tracking, see our mini computer and embedded coverage.
