Applications

The CY7C68300C/301C and CY7C68320C/321A implement

a USB 2.0 bridge for all ATA/ATAPI-6 compliant mass storage

devices, such as the following:

■ Hard drives

■ CD-ROM, CD-R/W

■ DVD-ROM, DVD-RAM, DVD±R/W

■ MP3 players

■ Personal media players

■ CompactFlash

■ Microdrives

■ Tape drives

■ Personal video recorders

The CY7C68300C/301C and CY7C68320C/321A support one

or two devices in the following configurations:

■ ATA/ATAPI master only

■ ATA/ATAPI slave only

■ ATA/ATAPI master and ATA/ATAPI slave

■ CompactFlash only

■ ATA/ATAPI slave and CompactFlash or other removable IDE

master

Introduction

The EZ-USB AT2LP™ (CY7C68300C/CY7C68301C and

CY7C68320C/CY7C68321C) implements a fixed-function

bridge between one USB port and one or two ATA- or

ATAPI-based mass storage device ports. This bridge adheres

to the Mass Storage Class Bulk-Only Transport Specification

(BOT) and is intended for bus and self powered devices.

The AT2LP is the latest addition to the Cypress USB mass

storage portfolio, and is an ideal cost- and power-reduction

path for designs that previously used Cypress’s ISD-300A1,

ISD-300LP, or EZ-USB AT2.

Specifically, the CY7C68300C/CY7C68301C includes a mode

that makes it pin-for-pin compatible with the EZ-USB AT2

(CY7C68300A).

The USB port of the CY7C68300C/301C and

CY7C68320C/321A (AT2LP) are connected to a host

computer directly or with the downstream port of a USB hub.

Software on the USB host system issues commands and

sends data to the AT2LP and receives status and data from

the AT2LP using standard USB protocol.
