NXP LS1021A时间敏感网络(TSN)参考设计

摘要:NXP公司的LS1021A是成本效益节能的高度集成系统级芯片(SoC),采用32位ARMCortexR-A7核,以及具有ECC保护L1和L2缓冲存储器,运营频率高达1GHz,CoreMarkR性能高达5000,主要用在网络和无线接入点,工业网关,工业自动化,打印,图像,企业和消费类M2M,网络和路由器以及智能无流.本文介绍了LS1021A主要特性,框图,物联网(IoT)智能连接解决方案以及LS1021A时间敏感网络(TSN)参考设计主要特性和电路图.

A member of the Layerscape (LS1) series, the LS102xA family is a cost-effective,

power-efficient, and highly integrated system-on-chip (SoC) design that extends the

reach of the NXP value-performance line of QorIQ communications processors.

Featuring a pair of extremely power-efficient 32-bit ARMR CortexR-A7 cores with

ECC-protected L1 and L2 cache memories for high reliability, running up to 1 GHz, and

providing pre-silicon CoreMarkR performance of over 5,000, the LS102xA family

delivers greater performance than any previous sub-4W communication processor.

This chip can be used for networking and wireless access points, industrial gateways,

industrial automation, printing, imaging, and M2M for enterprise and consumer

networking and router applications.

The QorIQ LS1 family, which includes the LS1021A communications processor, is built on Layerscape architecture, the industry’s first software-aware, core-agnostic networking architecture to offer unprecedented efficiency and scale..

A member of the value-performance tier, the QorIQ LS1021A processor provides extensive integration and power efficiency for fanless, small form factor enterprise networking applications. Incorporating dual ARM® Cortex®-A7 cores running up to 1.2 GHz, the LS1021A processor is engineered to deliver CoreMark® performance of over 7,000, as well as virtualization support, advanced security features and the broadest array of high-speed interconnects and optimized peripheral features ever offered in a sub-3 W processor....
