摘　　要：USB总线因其便捷的特性使得其应用越来越广泛,电子市场上带有USB接口的设备也越来越多,USB总线取代传统的老式接口必将成为一种趋势。而ISA总线是工业标准总线架构,在工控领域中历史悠久,是最早的系统级总线。ISA总线如今在工业控制领域的主要作用就是扩展中低速设备接口,因为工控领域中要控制的设备往往非常多,所以ISA总线在工业领域中仍然起着非常重要的作用。本文的主要目的是利用CH375芯片完成USB总线到ISA总线的转接。USB bus because of the convenient features that make its application more and more extensively, USB interface equipments become more and more in the electronic market, USB bus to replace the traditional old-fashioned interface will become a trend. While ISA bus the industry standard architecture, which survives a long time in the industrial area, is the first system-level bus. In nowadays, the major role of ISA bus in the industrial area of control is expanding low-speed interface devices, as equipments to be controlled in the field of industrial is numerous, so ISA bus stiff plays a very important role in the industrial field. The main purpose of the paper is to design the USB bus to the ISA bus adapter by the chip of CH375.
