The nRF5340 is implemented based on the nRF51 and nRF52 series multiprotocol SoCs that are used worldwide.
It introduces a new architecture based on dual-processor hardware with advanced security features and supports major RF protocols including Bluetooth® 5.1, Bluetooth Low Energy (Bluetooth LE), Bluetooth Mesh, Thread, and Zigbee.
The nRF5340 SoC is designed to meet operating temperatures extended up to 105°C and, with support for multiprotocol and the latest security features, is an ideal solution for professional lighting and industrial applications.
Furthermore, it is equipped with a high-performance application processor along with abundant 512KB RAM, fulfilling the requirements of complex next-generation wearable devices.
The QSPI peripheral has been extended to interface with external memory at 96MHz, and a 32MHz high-speed SPI peripheral is integrated to interface with displays and complex sensors.
For the highest level of security, the nRF5340 integrates Arm CryptoCell-312, Arm TrustZone® technology, and Secure Key Storage.
This protects the SoC from malicious attacks and supports advanced Root of Trust (RoT) and secure firmware updates.
Additionally, it supports a new multiprotocol 2.4GHz wireless specification optimized for power consumption with TX current of 3.2mA (0dBm TX power, 3V, DC/DC) and RX current of 2.6mA (3V, DC/DC), as well as enhanced dynamic multiprotocol capabilities.
Using Bluetooth LE on smartphones, it can perform Bluetooth LE and Bluetooth Mesh, Thread, and Zigbee operations for mesh network provisioning, commissioning, and interoperability, and the radio supports all Bluetooth 5.1 Direction Finding features.
This SoC also incorporates XTAL load capacitors for 32MHz and 32.762kHz crystals, enabling a reduction of up to 4 external components compared to the existing nRF52 series, as well as reducing Bill of Materials (BOM) and solution size.
The nRF5340's software development kit, nRF Connect SDK, provides a solution that integrates the Zephyr RTOS, Bluetooth LE protocol stack, application examples, and hardware drivers.
With additional support features for the nRF5340, it also supports low-power cellular IoT and low-power, short-range wireless development capabilities.
The SDK is officially hosted on GitHub with source code management available through Git, and SEGGER Embedded Studio IDE is also provided free of charge.
Meanwhile, Nordic is currently supplying the nRF5340 PDK (Preview Development Kit), an economical single-board-based preview development kit for the nRF5340 through Nordic's distribution channels and includes an onboard SEGGER J-Link debugger for programming and debugging of the SoC.
The nRF5340 SoC engineering samples will be supplied in a 7x7mm aQFN package supporting 48 GPIO pins in the near future.
