Arm cor-M33 듀얼 코어 프로세서의 설계를 기반으로 하는 nRF5340은 고성능 애플리케이션 프로세서, 프로그래밍 가능한 초저전력 네트워크 프로세서 및 보안 기능을 저전력 다중 프로토콜 SoC에 통합합니다. 동시에 이 칩은 동적 다중 프로토콜 지원을 강화하고 Bluetooth 5.1 , 저전력 Bluetooth, Bluetooth Mesh , Thread 및 Zigbee 프로토콜을 지원합니다. 저전력 블루투스를 사용하는 스마트폰으로 구성하거나 디버깅할 수 있으며 메시 네트워크와 상호 작용할 수 있습니다. 무선 송신기 에는 모든 Bluetooth 5.1 방향 찾기 기능이 장착되어 있습니다. nRF5340은 1.7~5.5V의 전원 공급 전압 범위에서 작동하므로 충전식 배터리와 USB 전원을 사용할 수 있습니다.

nRF5340은 3.2ma(0dbm 전송 전력, 3V, DC/DC)의 전송 전류와 2.6ma(3V, DC/DC)의 수신 전류를 가진 새로운 전력 최적화 다중 프로토콜 2.4ghz 라디오를 통합합니다. 수면 전류는 1.1A로 낮았습니다.

The nRF5340 launched this time, the main processor Application processor is responsible for the calculation of complex functions and bluetooth protocol stack. It adopts the Arm architecture -m33 under the Arm architecture that has always been used by Nordic, and mounts DSP and floating point functions at the same time, which can be used for third-party development and Application. The kernel runs at up to 128 MHz, supports voltage and frequency regulation, and contains dedicated 1 MB of flash memory and 512 KB of RAM memory, which can meet the needs of the next generation of cutting-edge wearable devices and significantly improve performance over the previous generation of nRF52840.

The sub-core Network processor can be used as the computation of additional and uncomplicated content, which also USES Arm corcor-m33, the kernel runs at 64 MHz (238 CoreMark), and is dedicated to 256 KB flash and 64 KB memory. The low power consumption and low duty cycle sensor acquisition during radio operation are optimized. Provides optimal implementation of the 2.4 GHz private protocol and ensures portability from the nRF51 and nRF52 series.

The two processors can work independently of each other, connect directly through the IPC, or wake up to each other, but consider their respective protection Settings.

In addition, the application processor also integrates security functions such as Arm cryptocell-312 security key storage, providing the highest level of security. It works by hardware accelerating common Internet encryption standards while providing system-wide hardware isolation for trusted software by creating secure and non-secure code execution areas on a single kernel. At the same time, the chip's integrated security features support firmware updates that can protect the chip from malicious attacks.

It is worth mentioning that nRF5340 integrates XTAL load capacitors for 32 MHz and 32.762 kHz crystals. Compared with Nordic's nRF52 series, the number of external components required is reduced by 4, thus reducing the material list and solution size.

It is reported that the 7x7mm aQFN package nRF5340 SoC engineering samples with 48 GPIO ports will soon be industrialized.
