Nordic nRF9151 – A smaller LTE-M/NB-IoT and DECT NR+ SiP with enhanced power efficiency and security

Nordic Semiconductor has announced the availability of its new nRF9151 SiP module adding to the nRF91 cellular IoT lineup. This new module includes a 64MHz Arm Cortex-M33 SoC, LTE-M/NB-IoT connectivity with a radio-frequency front-end (RFE) for cellular support, and DECT NR+ connectivity.

All this comes with a 20% smaller footprint and additional support for Power Class 5 20 dBm alongside Class 3 (23 dBm) compared to the Nordic nRF9161 SiP module also designed to power cellular IoT and non-cellular 5G solutions that was introduced just last month.

Nordic nRF9151 SiP: a low-power module with Arm Cortex-M33, LTE-M/NB-IoT, DECT NR+, 20% smaller footprint, and Power Class 5 20dBm support.

Nordic nRF9151 SiP module specification:

  • Processor and Memory – 64 MHz Arm Cortex-M33, 1 MB flash, and 256 KB SRAM.
  • Modem – Integrated LTE-M/NB-IoT and DECT NR+ with support for 3GPP Release 14 LTE-M/NB-IoT.
  • Location Tracking – Built-in GNSS receiver and support for cellular-based location features.
  • Security – Arm TrustZone, CryptoCell for cryptographic operations, true random number generator (TRNG).
  • Power Options – Supports Power Class 5 (20 dBm) in addition to the existing Power Class 3 (23 dBm), offering greater flexibility for battery-powered devices.
  • Compact Design – 20% smaller footprint compared to its predecessor, the nRF9161, enabling more compact and space-efficient product designs.
  • Firmware and software tools
    • Firmware Updates – Secure Firmware Over The Air (FOTA) updates.
    • DECT NR+ Stack – Enables massive mesh applications with reliability and scalability.
    • Development Tools – nRF Connect SDK and nRF Connect for Desktop for diverse development needs.

As we noted during the launch of the nRF9161 last month, DECT NR+ is a new technology using 5G’s core features for local wireless connectivity at 1.9GHz. It provides low-latency, reliable connections, and supports large mesh networks with up to one million nodes.

In terms of software support, the nRF9151 is fully compatible with the nRF9161 and nRF9131, sharing modem firmware. Developers can use the nRF Connect SDK in VS Code for essential tools and the nRF Connect for Desktop for network tasks. There’s also an online course at the Nordic Developer Academy for quick cellular IoT learning with the nRF9161 DK.

At the time of writing, there’s no specific development board for the nRF9151 SiP module, but Nordic plans to release one when the product is widely available. That being said the nRF9151 is available for sampling now, but pricing and general availability details haven’t been shared yet. For more information, visit Nordic’s product and press release pages.
