Introduction

The nRF9160 is a low-power cellular IoT (Internet of Things) solution, integrating an ARM® Cortex®-M33 processor with advanced security features, a range of peripherals, as well as a complete LTE modem compliant with 3GPP LTE release 13 Cat-M1 and Cat-NB1, and 3GPP LTE release 14 Cat-NB1 and Cat-NB2 standards.

The ARM® Cortex-M33 processor is exclusively for user application software, and it offers 1 MB of flash and 256 kB of RAM dedicated to this use. The M33 application processor shares the power, clock and peripheral architecture with Nordic Semiconductor nRF51 and nRF52 Series of PAN/LAN SoCs, ensuring minimal porting efforts.

The peripheral set offers a variety of analog and digital functionality enabling single-chip implementation of a wide range of cellular IoT (Internet of Things) applications. ARM® TrustZone® technology, Cryptocell 310 and supporting blocks for system protection and key management, are embedded to enable advanced security needed for IoT applications.

The LTE modem integrates a very flexible transceiver that in hardware supports frequency range from 700 to 2200 MHz (through a single 50 Ω antenna pin), and a baseband processor handling LTE Cat-M1/NB1/NB2 protocol layers L1-L3 as well as IP upper layers offering secure socket API for the application. The modem is supported by pre-qualified software builds available for free from Nordic Semiconductor.

On specific nRF9160 device variants, the LTE modem supports A-GPS operation during sleep intervals in the LTE operation (RRC idle and PSM modes).

Note: Cat-NB2 is supported in LTE modem HW, but needs modem firmware support to get enabled. Please refer to nRF9160 modem firmware release notes found under nRF91 FW binaries downloads concerning availability of Cat-NB2 feature support".
