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.
