Features
Fixed-function mass storage device–requires no firmware
code
USB
Mass Storage Class Bulk-Only
specification-compliant
(version 1.0)
USB 2.0-certified (TID# 40001426)
Integrated USB transceiver
High-speed (480-Mbit) and full-speed (12-Mbit) support
USB Suspend/Resume, Remote Wakeup support
Two power modes of operation–self-powered and USB bus-
powered
Low power consumption allows for bus-powered opera-
tion
VBUS-powered CF support
True USB portable HDD support
Compact 80-pin TQFP package with a Lead-Free option
ATA/ATAPI-6
specification-compliant–provides support for
mass storage devices larger than 137GB
5V tolerant inputs, 3.3V output drive
Flexible USB descriptor and configuration retrieval sources
I
2
C-compatible serial ROM interface
ATA interface using vendor-specific ATA command (FBh)
implemented on ATAPI or ATA device
Default on-chip ROM contents for manufacturing/devel-
opment
2-Kbyte SRAM data buffer for ATA/ATAPI data transfers
ATA interface supports ATA PIO modes 0–4, UDMA modes
0–4 (multiword DMA not supported). ATA interface
operation mode is automatically selected during device
initialization or manually programmed with I
2
C-compatible
configuration data
Automatic detection of either Master or Slave ATA/ATAPI
devices
Mode Page 5 Support–increased support for formatting
removable media devices
ATA Interrupt support for ATAPI devices–offers more robust
ATA support across OS platforms
System event notification via Vendor-specific ATA
command
Input pin for media cartridge detection or ejection request
USB bus state indications (Reset, FS/HS mode of oper-
ation, Suspend/Resume, Bus/Self-powered)
Three General Purpose I/O (GPIO) pins
Multiple LUNs supported within a single ATAPI device
ATA translation provides seamless ATA support with
standard MSC drivers
Additional ATA command support provided by vendor-
specific ATACBs (ATA command blocks utilizing the MSC
Command Block Wrapper)
Provisions to share ATA bus with other hosts (e.g.
USB/1394 dual device)
Manufacturing interconnect test support provided with
vendor-specific USB commands:
Read/Write access to relevant ASIC pins
Manufacturing Interconnect Test Tools
Utilizes inexpensive 30-Mhz crystal for clock source.
