help Nordic Semiconductor nRF5340 FAQ

What makes the Nordic Semiconductor nRF5340 different from other nRF SoCs?

The nRF5340 is Nordic's first dual-core processor, featuring an application core (Arm Cortex-M33) and a separate network core (Arm Cortex-M33) dedicated to running wireless protocol stacks. This architecture lets developers run heavy application code on one core while the other handles Bluetooth Mesh and other radio tasks without performance interference.

What wireless protocols does the nRF5340 support?

The nRF5340 supports Bluetooth Low Energy, Bluetooth Mesh, Thread, Zigbee, IEEE 802.15.4, and NFC-A, with protocol stacks updated through firmware revisions. This multi-protocol capability makes it suitable for complex IoT deployments that require concurrent wireless standards on a single chip.

Can the nRF5340 be programmed with the nRF Connect SDK?

Yes, the nRF5340 is fully supported by Nordic's nRF Connect SDK, which is built on the Zephyr RTOS. The SDK provides protocol stacks, Bluetooth Mesh models, and sample applications for both the application and network cores, with separate firmware images flashed to each processor.
