基于ISP1362的USB OTG接口设计

ISP1362是飞利浦公司推出的OTG解决方案系列产品，它在单芯片上集成了一个OTG控制器、一个高级主控制器（PSHC）和一个基于飞利浦ISP1161的设备控制器。首先对USBOTG进行简介，然后介绍了ISP1362的结构特点，在此基础上设计了一种基于ISP1362的USBOTG接口模块，该接口可以工作在主／从机两种模式，作为主机可以对USB设备进行操作，作为从机可以连接主机进行工作。文中给出了接口的软硬件设计方案。

Design of USB OTG Interface Based on ISP1362

ISP1362 is one of the serial products designed by the Philips Corporation to solve the OTG problem.It is a single-chip USB QTG controller integrated with the advanced Philips Slave Host Controller （PSHC） and the Philips ISP1161 Device Controller （DC）.In the paper,USB QTG is introduced firstly;Secondly,the structure and characteristics of ISP1362 are introduced; then an interface of USB OTG which can works as host or peripheral is designed,as a host,it can operate the USB Device; as a peripheral,it can connect with host to work.The design of software and hardware is afforded in this paper.
