基于LPC2220和ISP1161A1的外部存储读写系统设计

Read and Write Extern Memory System Based on LPC2220 and ISP1161A1

为使ARMLPC2220嵌入式系统对支持USB2.0协议的外部存储器进行快速准确的读写操作,设计了以Philips公司生产的ARMLPC220为处理器,ISP1161A1为USB主控芯片的系统,该系统经实践运行,实现了对支持USB2.0协议的外部存储器快速准确和可靠的数据通信。

To make ARM LPC2220 embedded system read and write the huge external memory which complies with the protocol of USB 2.0,a system had designed and realized,using the ARM LPC2220 microprocessor and the host controller ISP1161A1 chips produced by the PHILIPS corporation,The designed system can communicate with the huge external memory very fast and stability by practice.
