RF-STAR Launched Development Kit Based on NRF5340
Nordic announced the launch of the nRF5340 high-end multi-protocol system-level chip. The chip to build in the Nordic nRF51 and nRF52 multi-protocol series chips, and at the same time introduced a dual processor hardware architecture, with high performance and low power consumption, extensibility, high heat resistance advantages, can be widely used in smart home, indoor navigation, professional lighting, industrial automation, wearable devices, and other complex Internet applications.
Based on the design of the Arm cor-m33 dual-core processor, the nRF5340 integrates high-performance application processors, programmable ultra-low power network processors, and security functions into a low-power multi-protocol SoC. At the same time, the chip also enhances dynamic multi-protocol support, and supports bluetooth 5.1, low-power bluetooth, bluetooth Mesh, Thread, and Zigbee protocols. It can be configured or debugged by smart phones using low-power bluetooth, and interact with Mesh networks. The wireless transmitter is equipped with all bluetooth 5.1 direction finding functions. The nRF5340 operates in a power supply voltage range of 1.7 to 5.5V, allowing rechargeable batteries and USB power.
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.
RF-Star's development kit based on nRF5340 will also be on the market, and wireless modules based on nRF5340 are currently under development.
