description Nordic nRF5340 SoC Overview
The nRF5340 is a dual-core System on Chip (SoC) based around Arm Cortex-M33 technology. It delivers Bluetooth 5.2 wireless connectivity and incorporates dedicated mesh networking support. This low power SoC is particularly useful for developers creating advanced Internet of Things (IoT) applications, especially those requiring robust wireless networks and long battery life. It’s well-suited for embedded development projects.
help Nordic nRF5340 SoC FAQ
Why does the Nordic nRF5340 have two cores?
The nRF5340 uses two Arm Cortex-M33 cores so application code and network tasks can be separated. That design helps developers run Bluetooth Low Energy connectivity while keeping the main application responsive.
What wireless standards does the nRF5340 support?
The nRF5340 supports Bluetooth Low Energy and is commonly associated with Bluetooth 5.2 class features. Nordic also positions it for mesh, Thread, Zigbee, and other 2.4 GHz IoT use cases through its software ecosystem.
What SDK is used with the nRF5340?
Nordic's nRF Connect SDK is the main software environment for nRF5340 development. It is based on Zephyr RTOS, which matters if your project needs production-grade Bluetooth stacks and RTOS scheduling.
How is nRF5340 different from nRF52840?
The nRF52840 is a widely used single-core Nordic SoC, while the nRF5340 moves to a dual-core Cortex-M33 architecture. The nRF5340 is better suited for more complex BLE products that need stronger application processing alongside wireless connectivity.
