The Nordic Semiconductor nRF9151 is a highly integrated SiP integrating LTE-M/NB-IoT/NTN, DECT NR+ modem, and GNSS. Designed to simplify the development of advanced cellular IoT devices, the device combines low-power connectivity, edge processing, and positioning capabilities in a compact module.
At the heart of the device is a 64 MHz Arm Cortex-M33 processor supported by 1 MB of flash memory and 256 kB of RAM. The integrated multimode modem supports LTE-M and NB-IoT connectivity, while built-in GNSS provides positioning functionality for location-based applications. Support for DECT NR+ also enables scalable mesh networking for large IoT deployments.
The SiP supports LTE bands from 700 MHz to 2200 MHz and offers both Power Class 3 (23 dBm) and Power Class 5 (20 dBm) output options, providing flexibility for battery-powered devices and helping to reduce peak power consumption. Compared with earlier devices in the series, the module offers a footprint reduction of around 20%, allowing designers to create more compact products.
