CY7C68300B/CY7C68301B

CY7C68320/CY7C68321

EZ-USB AT2LP™ USB 2.0 to ATA/ATAPI Bridge

• Support for CompactFlash and one ATA/ATAPI device

1.0 Features (CY7C68300B/CY7C68301B and

CY7C68320/CY7C68321)

• Can place the ATA interface in high-impedance (Hi-Z) to

allow sharing of the ATA bus with another controller (e.g.,

an IEEE-1394 to ATA bridge chip or MP3 Decoder)

• Fixed-function mass storage device—requires no firmware

code

• Support for board-level manufacturing test via USB

interface

• Two power modes: Self-powered and USB bus-powered to

enable bus powered CF readers and truly portable USB

hard drives

• Low-power 3.3V operation

• FullycompatiblewithnativeUSBmassstorageclassdrivers

• Certified compliant for USB 2.0 (TID# 40460273), the USB

Mass Storage Class, and the USB Mass Storage Class

Bulk-Only Transport (BOT) Specification

• Cypress mass storage class drivers available for Windows

(98SE, ME, 2000, XP) and Mac OS X

• Operates at high (480-Mbps) or full (12-Mbps) speed USB

• Complies with ATA/ATAPI-6 specification

1.1

Features (CY7C68320/CY7C68321 only)

• Supports HID interface or custom GPIOs to enable features

such as single button backup, power-off, LED-based notifi-

cation, etc.

• Supports 48-bit addressing for large hard drives

• Supports ATA security features

• Supports all ATA commands via ATACB function

• Supports mode page 5 for BIOS boot support

• Lead-free 56-pin QFN and 100-pin TQFP packages

• CY7C68321 is ideal for battery-powered designs

• CY7C68320 is ideal for self- and bus-powered designs

• SupportsATAPIserialnumberVPDpageretrievalforDigital

Rights Management (DRM) compatibility

• Supports PIO modes 0, 3, 4, multiword DMA mode 2, and

UDMA modes 2, 3, 4

1.2

Features (CY7C68300B/CY7C68301B only)

• Pin-compatible with CY7C68300A (using Backward

Compatibility mode)

• Uses one external serial EEPROM for storage of USB

descriptors and device configuration data

• Lead-free 56-pin SSOP and 56-pin QFN packages

• CY7C68301B is ideal for battery-powered designs

• CY7C68300B is ideal for self- and bus-powered designs

• ATA interface IRQ signal support

• Support for one or two ATA/ATAPI devices
