原标题：Avnet MicroZed基于Xilinx Zynq-7000低成本开发方案

　　Avnet公司的MicroZed开发板是基于Xilinx公司的Zynq®-7000全编程SoC器件的低成本开发板,其独特的设计既可用作基本SoC实验的独立评估板,也可配合载卡用作嵌入式的模块上系统(SOM).该套件包含了开发产品, IoT支持和工业处理系统所需的必备模块.可支持设计人员开发边界到云端的基于互联网连接的解决方案,能迅速提升具备认知能力的物联网解决方案.主要用在ADAS,医疗电子,小型蜂窝基带,机器视角系统,4K/2K超高清电视机以及多功能打印机.本文介绍了开发板MicroZed主要特性,框图,电路图,材料清单和PCB设计图.

　　MicroZed™ is a low-cost development board based on the Xilinx Zynq®-7000 All Programmable SoC. Its unique design allows it to be used as both a stand-alone evaluation board for basic SoC experimentation, or combined with a carrier card as an embeddable system-on-module (SOM). MicroZed contains two I/O headers that provide connection to two I/O banks on the programmable logic (PL) side of the Zynq®-7000 All Programmable SoC device. In stand-alone mode, these 100 PL I/O are inactive. When plugged into a carrier card, the I/O are accessible in a manner defined by the carrier card design.

　　In addition to the evaluation kit, MicroZed is also available for volume purchase as a module only (no cable, license voucher, or uSD Card). This System-On-Module or SOM version of MicroZed comes in either the Zynq 7Z010 or 7Z020 version.
