The OXU931SF is a single chip solution for bridging between USB2.0 and hard
disks. Optimized for performance and low cost of ownership, the OXU931SF is
ideal for creating external storage devices which connect to a PC or Mac via the
USB2.0 port.
The integrated ARM7 and external flash enable the development of customized
solutions to exactly match the customers’ requirements.
Because it requires minimal external components and offers an integrated
USB2.0 PHY and SATA PHY, the OXU931SF enables designers to create
products with a low bill-of-material.
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.
