摘要/Abstract

摘要： 在许多数码产品应用中，存在计算机USB接口不足，使用各种数码卡时需配备专用读卡器的问题。为解决这些问题，本文使用FE1.1S和AU6437芯片设计一种多功能USB集线器，可提供一个SD卡和Micro SD卡接口，以及两个标准USB 2.0扩展口。经测试，本设计硬件功能完善，性能稳定，符合USB 2.0标准，为多功能高速读卡器的设计提供了良好的技术参考和依据。

Abstract: In the application of many digital products, there are common problems that PC Universal Serial Bus (USB) connectors are relatively insufficient and each digital card matches to its specific reader. To solve these problems, the chips of FE1.1S and AU6437 are used to design a set of multi-function USB hub which includes a connector of SD card and micro SD card, respectively, and two standard USB connectors. After testing, the hardware of this design has perfect functions and stable performances, which meets Universal Serial Bus Specification revision 2.0. It is believed that this study provides some references and proofs to the design of multi-func tional high speed reader.
