Nordic Semiconductor releases the world’s first Arm Cortex-M33 dual-core processor wireless SoC for the most demanding low-power IoT applications

Oslo, Norway – November 14, 2019 – Nordic Semiconductor announced the launch of the nRF5340TM high-end multi-protocol system-on-chip (SoC), the first member of the next-generation nRF5 series of SoCs. nRF5340 is based on Nordic’s proven and widely adopted nRF51 and nRF52 series of multi-protocol SoCs. At the same time, it introduces a new flexible dual-processor hardware architecture with advanced security features, and supports Bluetooth 5.1/Bluetooth Low Energy (Bluetooth Low Energy) Energy /Bluetooth LE), Bluetooth Mesh, Thread and Zigbee and other major RF protocols.

The nRF5340 SoC is designed to extend the operating temperature to 105oC, while supporting multiple protocols and advanced security features, making it very suitable for professional lighting and industrial applications. In addition, this SoC’s high-performance application processor also has 512 KB RAM large memory, which can meet the needs of the next generation of cutting-edge wearable devices. The device has an extended QSPI peripheral interface that can be connected to an external memory at 96 MHz. It also integrates a 32 MHz high-speed SPI peripheral that can be used as a Display and complex sensor interface.

nRF5340 integrates ArmTrustZone’s Arm CryptoCell-312 technology and security key storage to provide the highest level of security. The device uses Arm CryptoCell-312 to hardware acceleration of the most common Internet encryption standards, while Arm TrustZone provides system-wide hardware isolation for trusted software by creating secure and non-secure code execution zones on a single core. The comprehensive security function of nRF5340 can realize advanced trust root and safe firmware update, while protecting SoC from malicious attacks.

nRF5340 is based on the Arm Cortex-M33 dual-core processor; one is a high-performance application processor with a running rate of up to 128 MHz (510 CoreMark) with dedicated 1 MB flash memory and 512 KB RAM; the other is a 64 MHz (238 CoreMark) fully programmable ultra-low power network processor with dedicated 256 KB flash memory and 64 KB memory. The powerful application processor is extremely efficient (65 CoreMark/mA), has an 8 KB two-channel associative cache, supports DSP and floating point functions, and provides voltage and frequency adjustment options. The application processor integrates Arm TrustZone’s Arm Cryptocell-312 and advanced security functions of security key storage, with various interface peripherals including NFC, USB, QSPI and high-speed SPI. The fully programmable network processor has higher energy efficiency (101 CoreMark/mA) and is optimized for low power consumption and low duty cycle sensor acquisition during radio operation. Programmable network processor access provides the optimal realization of the 2.4 GHz private protocol, ensuring the feasibility of porting from the nRF51 and nRF52 series.

nRF5340 integrates a new power-optimized multi-protocol 2.4 GHz radio with a TX current of 3.2 mA (0 dBm TX power, 3 V, DC/DC) and an RX current of 2.6 mA (3 V, DC/DC). Sleep current is as low as 1.1 A. This SoC is characterized by enhanced dynamic multi-protocol support, concurrent support for Bluetooth low energy and Bluetooth mesh/Thread/Zigbee operations, and can be configured/debugged through a smartphone using Bluetooth low energy, and interacts with the mesh network. The radio has all the functions of Bluetooth 5.1 direction finding. nRF5340 can work in the power supply voltage range of 1.7 V to 5.5 V, allowing power supply from rechargeable batteries and USB. The SoC also integrates XTAL load capacitors for 32 MHz and 32.762 kHz crystals. Compared with Nordic’s nRF52 series, the number of external components required is reduced by four, reducing the bill of materials (BOM) and reducing the solution size .

nRF5340’s software development kit nRF Connect SDK provides a complete solution, which integrates Zephyr RTOS, Bluetooth low energy protocol stack, application examples and hardware drivers. nRF Connect SDK is a reliable solution for developing commercial products based on nRF9160 SiP. With support for nRF5340, this SDK unifies the development of low-power cellular IoT and low-power short-range wireless applications. nRF Connect SDK is publicly hosted on GitHub, source code management is provided by Git, and free SEGGER Embedded Studio IDE support is provided. Nordic also launched a low-cost nRF5340 single-board preview development kit nRF5340 PDK. Developers can use all the functions and all GPIOs of nRF5340. The PDK also has an on-board SEGGER J-Link debugger for SoC programming and debugging.

Kjetil Holstad, Director of Product Management at Nordic Semiconductor, said: “Bluetooth, Thread, Zigbee, and other low-power wireless technologies now constitute a key part of the Internet of Things. Developers are already developing projects based on real estate technology, location services, medical, smart home, and industrial Future commercial products for highly complex applications such as the Internet of Things. These applications require higher computing power and security, but developers expect Nordic’s wireless solutions to remain compact and energy-efficient.”

“The nRF5340 SoC is designed to meet these needs and more. This product is not only the crystallization of Nordic’s decades of experience in the ultra-low-power wireless field, but also a summary of Nordic’s experience in developing and supporting nRF51 and nRF52 series SoCs over the past seven years. It is the result of the world’s most experienced low-power wireless product research and development team focusing on product development for several years. By using nRF5340 and nRF Connect SDK together, developers can easily build wireless applications that have not been possible so far.”

Now customers can order nRF5340 PDK through Nordic agents. The engineering sample of nRF5340 SoC in a 7×7 mm aQFN package with 48 GPIO ports will soon be commercialized.
