摘要
讨论了基于 USB(Universal Serial Bus)接口的非接触式 IC卡读卡器的实现方法。该读卡器采用 W77E58作为 CPU,并使用 Future Technology Devices Intl.L td.(简称 FTDI公司 )的 FT2 45BM芯片扩展一个高速 USB接口 ,用 Philips公司的兼容 ISO1 4 443 A规范的读卡器专用集成电路 -RC50 0 ,实现了低成本的带 USB接口的非接触式 IC卡读卡器。所设计的读卡器完全兼容 USB1 .
This paper probes into a method that is used to design contactless IC card reader with USB interface. The reader is based on chip W77E58 with USB interface device using FT245BM and with the help of ISO14443A compatible reader chip RC500. A low cost contactless IC card reader with USB interface is realized. The reader's USB interface port is fully compatible with USB1.1 specification.
