Overview

The nRF5340 is the world’s first wireless System-on-Chip (SoC) with two Arm®

Cortex®-M33 processors. The combination of two flexible processors, the

advanced feature set, and an operating temperature up to 105 °C, makes it

the ideal choice for LE audio, professional lighting, advanced wearables, and

other complex IoT applications.

All-in-one

The nRF5340 is an all-in-one SoC, including a superset of the most prominent

nRF52® Series features. Features like USB, Bluetooth 5.2, up to 105 °C operating

temperature, and more, are combined with more performance, memory,

integration, while minimizing current consumption.

High-performance application processor

The application processor is optimized for performance and can be clocked at

either 128 or 64 MHz, using voltage-frequency scaling. The highest performance

(514 CoreMark) is achieved with 128 MHz, while running at 64 MHz offers a more

efficient option (73 CoreMark/mA). The application processor has 1 MB Flash,

512 KB RAM, a floating-point unit (FPU), an 8 KB 2-way associative cache and

DSP instruction capabilities.

F

ully-programmable network processor

The network processor is clocked at 64 MHz and is optimized for low power

and efficiency (101 CoreMark/mA). It has 256 KB Flash and 64 KB RAM. It is

fully programmable, enabling the developer to select which parts of the code

to run with the highest efficiency, in addition to the wireless protocol stack.

Next level security

The nRF5340 takes security to the next level by incorporating Arm Crypto-

Cell-312, Arm TrustZone®, and Secure Key Storage. Arm TrustZone efficiently

provides system-wide hardware isolation for trusted software by separating

between secure and non-secure regions on a single core. The security attrib-

utes of the Flash, RAM, and peripherals are easily configured through the nRF

Connect SDK. The Arm CryptoCell-312 hardware accelerates the strong ciphers

and encryption standards required in the most security-conscious IoT products.

Secure Key Storage is enabled by the Key Management Unit (KMU) peripheral,

where the keys are physically isolated from processor access, and only the

Arm CryptoCell-312 can access the secure keys. The secure bootloader in the

nRF Connect SDK establishes a root-of-trust and extends this to a chain-of-trust

by only booting software that has a verified signature. The bootloader also

verifies that all incoming device firmware updates originate from an authen-

ticated source.
