Overview
The nRF5340 is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. The nRF5340 is an all-in-one SoC, including a superset of the most prominent nRF52® Series features. Features like Bluetooth® Direction Finding, high-speed SPI, QSPI, USB, up to 105 °C operating temperature, and more, are combined with more performance, memory, and integration while minimizing current consumption.
The nRF5340 SoC supports an extensive range of wireless protocols. It supports Bluetooth Low Energy and is capable of all AoA and AoD roles in Bluetooth Direction Finding, in addition, Bluetooth Long Range and 2 Mbps.
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 5.3, up to 105 °C operating temperature, and more, are combined with more performance, memory, 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 at 66 CoreMark/mA) is achieved with 128 MHz, while running at 64 MHz offers a more efficient option (257 CoreMark at 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.
Fully-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 attributes 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.
