2. Codes Development Using Nordic Tools
Development tools from Nordic and other third party development tools recommended by Nordic should be
used.
Over-The-Air DFU
The nRF52840 is supported by an Over-The-Air Device Firmware Upgrade (OTA DFU) feature. This allows for
in the field updates of application software and SoftDevice.
nRF Connect SDK
nRF Connect SDK is a scalable and unified software development kit for building products based on all our nRF52,
nRF53 and nRF91 Series wireless devices. It offers developers an extensible framework for building size-optimized
software for memory-constrained devices as well as powerful and complex software for more advanced devices and
applications. It integrates the Zephyr RTOS and a wide range of samples, application protocols, protocol stacks, libraries
and hardware drivers.
For developing Bluetooth Low Energy, Thread and Zigbee products, the nRF Connect SDK contains all needed software,
including protocol stacks. For developing cellular IoT products it contains everything except the LTE modem firmware
that must be downloaded separately from the nRF9160 SiP product page. See the cellular IoT software for more details.
nRF Connect SDK also offers an unique integration of HomeKit Accessory Development Kit for developing products
using both HomeKit over Thread and HomeKit over Bluetooth Low Energy. It is a highly optimized solution that enables
battery-powered products with both the HomeKit Accessory Protocol (HAP) and application firmware running on a single
chip. MFi licensees can get access to the HomeKit repository by contacting us via Nordic DevZone private ticket.
nRF Connect SDK offers a single code base for all our devices and software components. It simplifies porting modules,
libraries and drivers from one application to another, thus reducing development time. By enabling developers to pick and
choose the essential software components for their application, high memory efficiency is guaranteed.
nRF Connect SDK is publicly hosted on GitHub, offers source code management with Git and has free SEGGER
Embedded Studio IDE support. Nordic runs continuous integration tests on the nRF Connect SDK code to ensure robust
and secure production quality code.
Development Tools
Nordic Semiconductor provides a complete range of hardware and software development tools for the nRF53 Series
devices. nRF53 DK board is recommended for firmware development.
Nordic software development tools can be downloaded.

nRF5340 is a wireless ultra-low power multiple core System on Chip (SoC) integrating two fully programmable
Arm Cortex M33 processors, advanced security features, a range of peripherals, and a multi protocol 2.4 GHz
transceiver. transceiver supports Bluetooth low energy.
The two Arm Cortex M33 processors share the power, clock, and peripheral architecture with Nordic
Semiconductor nRF51, nRF52, and nRF91 Series of PAN/LAN SoCs, ensuring minimal porting efforts. The
application core is a full-featured Arm Cortex M33 processor including DSP instructions and FPU and running
at up to 128 MHz with 1MB of flash and 512 KB of RAM. The option to run the application processor at 64 MHz
allows the CPU to increase energy efficiency. The network core is an Arm Cortex M33 processor with a
reduced feature set, designed for ultra-low power operation. It runs at a fixed 64 MHz frequency and contains
256 KB of flash and 64 KB of RAM.
The peripheral set offers a variety of analog and digital functionality enabling single chip implementation of a
wide range of applications. Arm trustZone technology, Arm cryptoCell-312, and supporting blocks for ysytem
protection and key management are embedded for the advanced security needed for IoT applications.
