Avnet公司的MicroZed開發(fā)板是基于Xilinx公司的Zynq?-7000全編程SoC器件的低成本開發(fā)板,其獨特的設(shè)計既可用作基本SoC實驗的獨立評估板,也可配合載卡用作嵌入式的模塊上系統(tǒng)(SOM).該套件包含了開發(fā)產(chǎn)品, IoT支持和工業(yè)處理系統(tǒng)所需的必備模塊.可支持設(shè)計人員開發(fā)邊界到云端的基于互聯(lián)網(wǎng)連接的解決方案,能迅速提升具備認知能力的物聯(lián)網(wǎng)解決方案.主要用在ADAS,醫(yī)療電子,小型蜂窩基帶,機器視角系統(tǒng),4K/2K超高清電視機以及多功能打印機.本文介紹了開發(fā)板MicroZed主要特性,框圖,電路圖,材料清單和PCB設(shè)計圖.

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.
