OXUF934DSB, FireWire 800/400, USB 2.0, eSATA to SATA Controller
Highlights
The OXUF934DSB is a high performance, configurable storage controller for
bridging between FireWire800, FireWire400, USB2.0, eSATA and SATA hard
disks.
General Features
o High performance dual SATA storage
controller
Optimized for performance and offering increased functionality on the external
SATA-to-SATA path, the OXUF934DSB supports a range of RAID and storage
applications targeted at users requiring maximum performance, reliability and
ease of use.
Key Features
o High performance dual SATA storage
controller
o Integrated SATA cores and PHYs
- Port can be configured for eSATA
device operation
- Supports SATA II Gen2m
specification and 3.0Gbps and
1.5Gbps interfaces
o Market proven 1394b PHY and Link
Layer with industry leading
performance
o Integrated 480Mbps USB2.0 high
speed core and PHY
The OXUF934DSB can be configured for FireWire800 / FireWire400 / USB to
dual SATA, or eSATA to SATA operation. When configured in dual SATA
mode, the integrated hardware RAID controller supports disk striping (RAID0)
for maximum performance or disk mirroring (RAID1) for maximum data
protection For higher speed connections, one of the SATA ports can be
configured as a device port enabling USB, FireWire800/400 and eSATA combo
applications.
o Integrated hardware RAID controller
supporting (over USB and FireWire):
- Disk striping (RAID0) for maximum
performance
- Disk mirroring (RAID 1) for
maximum data protection
- Disk spanning for large capacity
single volume
The OXUF943DSB shares a common software base with other devices in
Oxford’s range of USB and FireWire storage controllers. In addition, Oxford
offers a comprehensive support package that includes evaluation boards,
reference designs, and software development kit.
Embedded ARM Processor
o External flash interface
o I2C interface for optional EEPROM
o USB and USB mass-storage compliant
o Support for USB Human Interface
Device (HID)
By managing the data flow, the on-chip ARM7 processor enables a whole new
series of standalone consumer electronic product to be developed in a simple
C/C++ programming environment.
o Support for button push apps
o 12 GPIOs allow easy product
customization
USB2.0
The embedded USB2.0 PHY supports both full and high speed, using bulk-only
transport Mass Storage Class device protocol. Its fast read and write transfers
ensure that the maximum possible host performance is maintained.
No additional USB host drivers are required, for either Windows® or Mac®
operating systems, for standard storage, button notification or GPIO control
applications.
FireWire
The embedded 1394 PHY and link layer supports both FW800 and FireWire400
and complies with the 1394-1995 and 1394-2000 specifications.
No additional 1394 host drivers are required for either Windows or Mac
operating systems for standard storage applications.
SATA Interface
The dual port SATA host with embedded PHY supports the latest revisions of the
SATA II specifications, including the Gen2m interface for eSATA devices.
Interface speeds of 3GHz and 1.5GHz deliver maximum performance with
minimum latency for external SATA storage.
