Product description

Dual-core Bluetooth 5.2 SoC supporting Bluetooth LE, Bluetooth mesh, NFC, Thread and Zigbee

The nRF5340 is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. The combination of two flexible processors, the advanced feature set, and an operating temperature up to 105 °C, makes it the ideal choice for LE Audio, professional lighting, advanced wearables, and other complex IoT applications.

The nRF5340 is an all-in-one SoC, including a superset of the most prominent nRF52® Series features. Features like Bluetooth® 5.2, high-speed SPI, QSPI, USB, up to 105 °C operating temperature, and more, are combined with more performance, memory and integration, while minimizing current consumption.

The application processor is optimized for performance and can be clocked at either 128 or 64 MHz, using voltage-frequency scaling. It has 1 MB Flash, 512 KB RAM, a floating-point unit (FPU), an 8 KB 2-way associative cache and DSP instruction capabilities. The network processor is clocked at 64 MHz and is optimized for low power and efficiency (101 CoreMark/mA). It has 256 KB Flash and 64 KB RAM.

The nRF5340 takes security to the next level. It offers trusted execution, root-of-trust and secure key storage security features. Arm TrustZone provides trusted execution by implementing a division between secure and non-secure Flash, RAM, peripherals and GPIOs. The state-of-the-art Arm CryptoCell-312 provides hardware-accelerated cryptography, and together with the key management unit (KMU) peripheral, root-of-trust and secure key storage are implemented.

The nRF5340 SoC supports an extensive range of wireless protocols. It supports Bluetooth Low Energy and is capable of all angle-of-arrival (AoA) and angle-of-departure (AoD) roles in Bluetooth Direction Finding. In addition it supports LE Audio, high-throughput 2 Mbps, Advertising Extensions and Long Range. Mesh protocols like Bluetooth mesh, Thread and ZigBee can be run concurrently with Bluetooth LE, enabling smartphones to provision, commission, configure and control mesh nodes. NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols are also supported.

Product description

Development kit for the nRF5340, a dual-core Bluetooth 5.2 SoC supporting Bluetooth Low Energy, Bluetooth mesh, NFC, Thread and Zigbee

The nRF5340 DK is the development kit for the nRF5340 System-on-Chip (SoC), containing everything needed to get started with development, on a single board. The DK supports development with an extensive range of wireless protocols. It supports Bluetooth Low Energy with features such as high-throughput 2 Mbps, Advertising Extensions and Long Range.

Mesh protocols like Bluetooth mesh, Thread and Zigbee can run concurrently with Bluetooth Low Energy, enabling smartphones to provision, commission, configure and control mesh nodes. NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols are also supported.

The DK is bundled with an NFC antenna that quickly enables testing of nRF5340’s NFC-A tag functionality. A SEGGER J-Link debugger is on the board, enabling full-blown programming and debugging, of both the nRF5340 SoC and external targets. All analog and digital interfaces, and GPIOs are available via headers and edge connectors. The kit is Arduino Uno Rev3 hardware compatible, meaning it can be easily interfaced with external device shields.

Four buttons and four LEDs simplify input and output to and from the nRF5340 SoC, and are all user-programmable. An on-board external memory is connected to the 96 MHz QSPI peripheral in the nRF5340 SoC.

The nRF5340 DK is typically powered via USB, but can be powered by a wide range of sources, within the supply range of 1.7 to 5.0 V. In addition to USB, it can be powered with external source, but also includes a CR2032 battery holder and a Li-Po battery connector, for in-field testing. Current consumption can be measured by using the dedicated current measurement pins, for example by using Nordic's Power Profiler Kit II.

The nRF Connect SDK is the software development kit for the nRF5340 SoC, and it has board support for the nRF5340 DK. It supports software development of Bluetooth Low Energy, Thread and Zigbee applications. It integrates the Zephyr RTOS, protocol stacks, samples, hardware drivers and much more.
