ABSTRACT In the early times, Centronics Parallel Port and Serial Port are used to communicate with PC. By using these interfaces, data can be transferred between PC and devices. As the time go by, Central Processing Unit performs much better than before, old interface, Centronics Parallel Port and Serial Port, can not reach the speed anymore. In order to solve this problem, a new interface was invented. The Universal Serial Bus is fast and flexible interface for connecting devices to computer. A mass storage device is a hardware which can provide access to data. Every time we load an application or save a file on a hard disk, its data can not share with other computers. This thesis describes USB mass storage device by using CY3686 USB development system manufactured by CYPRESS is used to realize USB transfer , and stores data in NAND Flash Memory.. ¦. USB mass storage device must implement these protocols and structures 1. Generic USB protocol.. This thesis describes USB 2.0 and use Bulk transfer.The USB 2.0 specification defines high speed at 480 megabits/sec and full speed at 12 megabits/sec. 2. SCSI command. USB hosts access mass storage devices via commands originally developed for devices that use Small Computer Systems Interface. 3. Flash memory protocol. The storage media’s controller typically supports a command set for accessing the media’s contents.By using CYPRESS special interface (GPIF, General Programmable Interface),it will be easier to control NAND Flash Memory. ii.
