2.0 Mass storage class peripheral controller intended for

use with standard ATAPI devices. The device consists of a USB 2.0 PHY and SIE, FI FO buff ers, embedded microprocessor with ex panded exte rnal p rogram ROM/Flash memory, and ATAPI compatible interface. The CS8818 uses 12MHz crystal to reduce the EM I issue. With flexible 32-bit I/O interface, the CS8818 can b e pro grammed to fit dif ferent situ ations in the USB 2.0 high speed ma ss storage class applications such as CD-ROM, CD-RW, DVD-R and DVD-RW, etc. sales@myson.com.tw www.myson.com.tw Rev. 1.0 April 200 3 page 1 of 41
