nxp公司的QorIQ® LS1012A是基于64位ARM® Cortex®-A53核的低功耗通信处理器,提供超过4000的CoreMark®性能,用于包处理和安全的硬件加速器,以及1W典型功耗通信处理器最好的整体性能.工作频率高达1GHz,主要用在可信赖的IoT网关,数据中心以太网驱动,建筑物和工作自动化,消毒类电子,网络存储(电池供电),智能家庭网关等.本文介绍了QorIQ LS1012A主要特性,框图和开发板QorIQ® FRDM-LS1012A主要特性,电路图,材料清单和PCB装配图.

Incorporating a 64-bit Arm® Cortex®-A53 core, the LS1012A processor delivers CoreMark® performance of over 4,000 as well as hardware acceleration for packet processing and security, and the best overall performance of any 1 W typical power communications processor.

CORE COMPLEX

The LS1012A processor integrates a single Arm Cortex-A53 core running up to 1 GHz with ECC-protected L1 and L2 caches and incorporates the same trust architecture and software compatibility of higher-tier Layerscape family devices. The LS1012A processor features 32 KB of L1 instruction and data cache and 256 KB of coherent L2 cache. In addition, the Cortex-A53 core features the NEON™ SimD module and dual-precision floating point unit (FPU). The memory controller supports 16-bit DDR3L memory devices at 1 GHz.

SYSTEM INTERFACES AND NETWORKING

The LS1012A processor features a three-lane, 6 GHz multi-protocol SerDes that provides support for high-speed interfaces, including up to two Gigabit Ethernet ports, DMA-controlled PCI Express® generation 2.0 port, and one SATA 3.0 port. The LS1012A processor also features dual USB controllers—one supporting SuperSpeed USB 3.0 with integrated PHY, the other supporting USB 2.0 functions. Additional interfaces include QuadSPI and support for SD/MMC.

The LS1012A includes a hardware packet forwarding engine (PFE) which offloads processing of IP packets from the main CPU, yielding higher performance and lower power than pure software processing can achieve. The PFE is capable of 2 Gbit/s IP forwarding even with the smallest packets, with virtually no CPU load.

COMPLETE ENABLEMENT, RICH ECOSYSTEM

For customer evaluation, the LS1012A processor is supported by an evaluation board featuring an integrated on-board probe for further cost savings, along with third-party platforms developed by NXP’s embedded board solution partners. Evaluation kits include a Linux® BSP with optimized drivers to support peripherals and a six-month evaluation license for CodeWarrior development tools. For quick product prototyping, NXP offers the FRYW-LS1012A board with a built-in mikroBUS®Click Module that opens the door to easy expansion through hundreds of powerful click modules supporting sensors, actuators, memories and displays. All LS series devices are supported by our Product Longevity Program to ensure a stable supply of products, as well as our extensive third-party ecosystem, the largest and most established in the communications market. In conjunction with our expertise and worldwide support infrastructure, the ecosystem helps customers accelerate their migration from both competitive solutions and from legacy NXP devices, preserve investment costs and reduce time-to-market.
