利用USB/UART桥接芯片进行USB接口的设计

The design of USB interface using USB/UART bridge chip

近几年来,USB接口得到了日益普遍的应用,针对USB接口的开发方法也随之日益丰富完善起来。利用USB/UART桥接芯片开发USB接口是一种较为简便易行的设计方法,这种方法可以适合大多数的USB小型系统的应用。本文以FTDI公司的FT8U232BM为例,对这种USB接口的设计方法进行了阐述。

USB interface applied widely in recent years, the developing methods for it are improved day by day. To design USB interface using USB/UART bridge chip is easy and feasible for USB mini system. This paper takes FT8U232BM of FTDI Corporation as an example to introduce the design method above-mentioned.
