[原創] Avnet PicoZed SOM模塊化系統開發方案

Avnet公司的PicoZed模塊化系統(SOM)是基于Xilinx Zynq-7000全編程(AP) SoC設計的超級靈活可靠的模塊化系統(SOM),為設計者提供引腳兼容的在7010,7015,7020和7030 Zynq-7000全編程(AP) SoC器件間靈活移植.PicoZed模塊內含存儲器,配置,以太網,USB 以及時鐘等支持大多數SoC設計核心所需的常見功能.主要用在嵌入模塊化系統,嵌入可視系統,馬達控制,測試測量,軟件定義無線電(SDR)以及工業自動化.本文介紹了開發板PicoZed SOM主要特性,框圖,電路圖,材料清單和PCB設計圖.

The PicoZed SOM is designed to operate while plugged into a Carrier Card or base module, not as a standalone module. Some documentation, such as Board Definition files, Board Support Packages, and Application examples only apply to a PicoZed / Carrier Card combination so this type of documentation will be posted under the PicoZed Carrier Card pages.

PicoZed™ is a highly flexible, rugged, System-On-Module, or SOMthat is based on the Xilinx Zynq?-7000 All Programmable SoC. Itoffers designers the flexibility to migrate between the 7010, 7015,7020, and 7030 Zynq-7000 All Programmable SoC devices in a pin-compatible footprint.

The PicoZed module contains the common functions required to support thecore of most SoC designs, including memory, configuration, Ethernet, USB,and clocks. It provides easy access to over 100 user I/O pins through three I/Oconnectors on the backside of the module. These connectors also supportaccess to dedicated interfaces for Ethernet, USB, JTAG, power and othercontrol signals, as well as the GTP/GTX transceivers on the 7015/7030 models.

The transceiver based 7015 and 7030 versions of PicoZed are a superset ofthe 7010/7020 version, adding four high-speed serial transceiver ports to theI/O connectors. Designers can simply design their own carrier card, plug-inPicoZed, and start their application development with a proven Zynq-7000 AllProgrammable SoC sub-system.
