The OXU931S is a single chip solution for bridging between USB2.0 and hard
disks. Optimized for performance and low cost of ownership, the OXU931S is
ideal for creating external storage devices which connect to a PC or Mac via the
USB2.0 port.
Because it requires no external memory and offers an integrated USB2.0 PHY
and SATA PHY, the OXU931S enables designers to create products with a
minimal number of external components.
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.
SATA Interface
The SATA host port with embedded PHY and controller supports the latest
revisions of the SATA II specifications and supports interface speeds of 1.5GHz
deliver maximum performance with minimum latency for single disk USB
external storage.
Development Support
For external MAC and PC storage solutions, Oxford Semiconductor offers a
selection of reference designs, development code, drivers, and evaluation kits.
