Document 001-05809 Rev. *A

Revised November 30, 2006

Features

• Fixed-function mass storage device—requires no firmware

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

enable bus powered CF readers and truly portable USB
hard drives

• Certified compliant for USB 2.0 (TID# 40490119), the USB

Mass Storage Class, and the USB Mass Storage Class
Bulk-Only Transport (BOT) Specification

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

USB

• Complies with ATA/ATAPI-6 specification

• Supports 48 bit addressing for large hard drives

• Supports ATA security features

• Supports any ATA command with the ATACB function

• Supports mode page 5 for BIOS boot support

• Supports ATAPI serial number VPD page retrieval for Digital

Rights Management (DRM) compatibility

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

and UDMA modes 2, 3, and 4

• Uses one small external serial EEPROM for storage of USB

descriptors and device configuration data

• ATA interface IRQ signal support

• Supports one or two ATA/ATAPI devices

• Supports CompactFlash and one ATA/ATAPI device

• Supports board-level manufacturing test using the USB I/F

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

allow sharing of the ATA bus with another controller (i.e., an
IEEE-1394 to ATA bridge chip or MP3 Decoder)

• Low-power 3.3V operation

• Fully compatible with native USB mass storage class drivers

• Cypress mass storage class drivers available for Windows

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

Features (CY7C68320C/CY7C68321C only)

• Supports HID interface or custom GPIOs to enable features

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

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

• CY7C68321C is ideal for battery-powered designs

• CY7C68320C is ideal for self- and bus-powered designs

Features (CY7C68300C/CY7C68301C only)

• Pin-compatible with CY7C68300A (using Backward

Compatibility mode)

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

• CY7C68301C is ideal for battery-powered designs

• CY7C68300C is ideal for self- and bus-powered designs
