Extensive wireless protocol support

The nRF5340 SoC supports an extensive range of wireless

protocols. It supports Bluetooth Low Energy and is capable of

all angle-of-arrival and angle-of-departure roles in Direction

Finding, in addition to LE Audio, Long Range, high-through-

put 2 Mbps and Advertising Extensions features. 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.

Designed for LE Audio

The SoC has been designed to meet the requirements of LE

Audio, enabling audio streaming over Bluetooth Low Energy.

LE Audio supports multi-stream synchronized audio for

applications such as earbuds, and Audio Sharing, whereby

a single audio source can broadcast to multiple recipients.

The nRF5340 radio supports Isochronous Channels, the

Bluetooth 5.2 feature required by LE Audio for streaming. LE

Audio also introduces the Low Complexity Communications

Codec (LC3), a high-quality, low-power audio compression

codec that can run efficiently on the nRF5340. The audio

data can be transferred to other parts of the system (AD/DA

converters, speakers, microphones) using the I²S and PDM au-

dio interfaces, which employ the nRF5340’s low-jitter audio

PLL clock source.

Ultra-low-power radio with great sensitivity

The nRF5340 SoC radio sets a new standard when it comes

to combining advanced features and minimizing current. The

0 dBm TX current is 3.4 mA, while the RX current is only 2.7

mA, resulting in a reduction of 29% and 41% when compar-

ing to the nRF52840 SoC. The RX sensitivity is -98 dBm, 3 dB

better than nRF52840, meaning that the nRF5340 provides 3

dB better sensitivity, while using 41% less current.

nRF Connect SDK

The nRF Connect SDK is the software development kit for

the nRF5340 SoC. It supports development of Bluetooth

Low Energy, Thread and Zigbee applications. It integrates

the Zephyr RTOS, protocol stacks, samples, hardware driv-

ers and much more.

nRF Connect SDK also supports the nRF9160, our LTE-M/

NB-IoT/GPS SiP, and the nRF52 Series. It is a common plat-

form for both cellular IoT and short-range development.

nRF5340 DK

The nRF5340 DK is the development kit for the nRF5340 SoC.

It is affordable, and has everything needed for development

on a single board. All features and GPIOs of the nRF5340 SoC

are made available to the developer, and it comes with an on-

board SEGGER J-Link debugger enabling both programming

and debugging of the nRF5340 SoC.

The nRF5340 SoC and the nRF5340 DK are available for

purchase through our distribution network.
