Nordic Semiconductor provided a 'sneak peek' of its upcoming nRF91 Series low power cellular IoT solution. Front and center of Nordic Semiconductor's upcoming nRF91 Series is a highly-integrated, low power, global multimode LTE-M / NB-IoT System-in-Package (SiP). The SiP integrates a complete low power cellular IoT system into a tiny 10x16x1.2mm package that integrates modem, transceiver, RF front end, dedicated application processor, Flash memory, power management, and crystal and passive components. With this level of integration the nRF91 SiP combines all the benefits of traditional cellular modules, including teleregulatory and cellular certifications, with ease-of-use, unprecedented integration, and the smallest form factor ever seen in the cellular industry to date.
Nordic is proud and excited to have Qorvo as a strategic partner for both the RF front end and the SiP development and manufacturing. The nRF91 SiP leverages Qorvo's RF front-end, advanced packaging, and MicroShield technology to deliver a unique, ultra-compact solution that combines high performance with low power consumption. The nRF91 Series supports global operation with a single SiP variant thanks to the combination of Nordic's multimode LTE-M / NB-IoT modem, SAW-less transceiver, and a custom RF front-end solution from Qorvo.
The nRF91 takes security for low power IoT devices to new heights by combining the inherent security of cellular connectivity with a cutting-edge security solution for the application hardware and software. The integration of an Arm Cortex-M33 processor and Arm CryptoCell-310 security IP enables an entire low power cellular IoT application to be implemented on an nRF91 SiP.
The built-in host processor features TrustZone for Armv8-M, helping secure application data, firmware, and peripherals using an isolated, trusted execution environment across the CPU and system. The nRF91 SiP also features built-in support for positioning via an integrated Assisted GPS (A-GPS) solution that combines cellular and GPS technology to deliver fast and accurate positioning.
The nRF91 SiP is based on Nordic's own nRF91 Series low power cellular IoT SoC. Jointly developed by Nordic's highly experienced cellular design team in Finland, and low power experts in Norway, the chip was developed from scratch to optimize the power, cost, and size savings enabled by the new LTE-M and NB-IoT cellular standards. The nRF91 Series includes a complete suite of software and easy-to-use development tools to accelerate innovation and product development.
