EZUSB的应用和设计

The Application and Design of EZUSB

Cypress半导体公司的EZUSB系列是一种紧密集成电路,对于USB外围设备提供了非常完整的解决方案。通过对EZUSB枚举模式的研究,了解EZUSB怎样通过本身的接口下载程序,以便更好的发掘设备的功能。介绍了EZUSB枚举模式和EZUSB的总线枚举中的过程,并给出了实现的方法和在设计中应注意的一些问题。

The Cypress Semiconductor EZUSB is a compact integrated circuit that provides a highly integrated solution for a USB peripheral device. We know that how EZUSB interface itself is used to download code via researching enumeration models of EZUSB, so that the functions of device are performed thoroughly. In this paper, we introduce the enumeration models of EZUSB, the procedure of EZUSB bus enumeration, the method of implementation and some problems to be paid attention to.
