The Oxford OXUF924DSA/B
is a high performance solution for bridging between SATA disks
and USB2.0, FireWire400, and FireWire800 (DSB only). The chip is used for creating external
storage solutions which connect to a PC & Apple Mac via the USB2.0 or FireWire port.
The UF924DSA/B contains a full USB2.0 link/Phy & FireWire link, minimising external components.
Key features
Integrated Dual SATA core & Phys operating at
1.5Ghz with 150Mbytes/s data rates
Dual SATA allows connection of 1 or 2 SATA
drives with hardware striping, spanning and
mirroring for ultimate performance. Alternatively,
one SATA port can be configured as an input
enabling eSATA to SATA.
Supports SATA II port multiplier specification
Comes complete with field upgradable firmware
that supports USB mass storage protocol, and
FireWire SBP2 (supported as standard by
Windows and Apple Mac)
Industry renowned ARM7, with plenty of spare
MIPs allowing customers to differentiate in
product software
Integrated 480Mbps USB2.0 link & Phy
Integrated IEEE1394A and IEEE1394B (for
DSB) link
Integral close coupled 8kbyte uP RAM
18Kbyte RAM for USB & FireWire data cache
12 GPIOs allow easy product customisation
176 pin BGA

OXUF924DS
FireWire400, FireWire800
& USB2.0 to Dual SATA Bridge
FireWire400/800
The OXUF924DSA supports FireWire400 while the
OXUF924DSB supports both FireWire400 and the latest highest
speed FireWire800.
USB2.0
The OXUF924DS supports both Full and High-Speed USB modes.
It's high performance FIFO manager together with high speed
architecture exceed the throughput capability of today's PCs,
ensuring it keeps pace as they continue to increase in speed.
SATA Interface
The SATA interface allows external storage products to follow the
current transition of hard disk drives from Parallel ATA to
Serial ATA.
RAID
The chip supports several RAID functions.
Striping,
allows two SATA disks to appear as a single higher
speed disk, by sharing the load between the two disks.
Mirroring,
writes the same data to both disks, so that data may
be recovered in the event of one drive failing
Spanning,
allows two drives to appear as one to the host machine
Embedded ARM processor
The on-chip ARM7TDMI enables product differentiation by
giving customers the option to develop custom software features
using the development kit. The firmware is field upgradable,
allowing products to be updated with the latest software. Software
development is carried out in a C/C++ programming environment.
Development tools and custom solutions
For external MAC and PC storage solutions, Oxford
Semiconductor offers a selection of reference designs,
development code, drivers, and evaluation kits.
Comprehensive application notes shorten learning curves and
simplify implementation.
