The OXUFS936DS is a Universal Interface (eSATA, FireWire800, FireWire400,
USB2.0) to dual SATA storage controller with integrated hardware RAID
engine. Delivering best-in-class performance across all interfaces, the
OXUFS936DS enables a range of external storage applications, including dual
disk RAID configurations.
The intgrated hardware RAID controller supports a range of RAID modes which
can deliver maximum performance (RAID 0) or maximum data protection
(RAID 1).
Integrating an eSATA device port, IEEE1394b link, USB2.0 device and dual
SATA host controllers the OXUFS936DS requires a minimal number of external
components and reduces total system BOM cost.
Embedded ARM Processor
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.
USB2.0
The embedded USB2.0 PHY supports both full and high speed, using bulk-only
transport Mass Storage Class device protocol. 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 FireWire800 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 embedded 3GHz SATA host interfaces supports the latest revisions of the
SATA II specifications. In addition the eSATA device port also supports the
Gen2m interface. Interface speeds of 3GHz and 1.5GHz deliver maximum
performance with minimum latency for external SATA storage.

Product Ordering Information
RAID
The chip supports several RAID functions, including:
Part Number
OXUF936DSFBAG
o
Striping (RAID 0) delivers the highest performance
but provides no data integrity or redundancy.
o
Mirroring (RAID 1) provides the highest level of data
integrity with 100% data redundancy.
o
Spanning (concatenation) presents all drives as a
single large volume.
