OXUF934DSA, FireWire 400, USB 2.0, eSATA to SATA Controller
Highlights
The OXUF934DSA is a high performance, configurable storage controller for
bridging between 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 OXUF934DSA 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 1394a PHY and Link
Layer with industry leading
performance
The OXUF934DSA can be configured for 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, FireWire400 and eSATA combo applications.
o Integrated 480Mbps USB2.0 high
speed core and PHY
o Integrated hardware RAID controller
supporting (over USB and FireWire):
- Disk striping (RAID0) for maximum
performance
The OXUF943DSA 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.
- Disk mirroring (RAID 1) for
maximum data protection
- Disk spanning for large capacity
single volume
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)
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
o Support for button push apps
o 12 GPIOs allow easy product
customization
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.
FireWire400
The embedded 1394 PHY and link layer supports 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.
