OXUS931SE, USB 2.0, eSATA to SATA Controller with Encryption
Highlights
General Features
o
High performance USB2.0 or eSATA
to single SATA storage controller
The OXUS931SE is a single chip solution for bridging between USB2.0 or
eSATA to SATA hard disks with an integrated cipher engine. Optimized for
performance, the OXUS931SE is ideal for creating secure external storage
devices or encryption dongles.
The integrated cipher engine provides advanced encryption and decryption
capabilities in hardware and enables OEMs to rapidly deploy full disk encryption
solutions, providing end users with peace-of-mind that their private content is
safe and secure in the event of theft or loss.
Integrating a USB2.0 device, an eSATA device, and a SATA host controller, the
OXUS931SE enables designers to create products with a minimal number of
external components
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
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 Interfaces
The embedded 3GHz SATA host interface supports the latest revision of the
SATA II specifications. In addition the eSATA device port also supports the
Gen2m interface. Interface speeds of 3GHz deliver maximum performance with
minimum latency for external SATA storage.

Encryption
The integrated hardware cipher engine supports real-time,
on-the-fly encryption / decryption of the data to the
Advanced Encryption Standard (AES), providing a means
whereby a users’ data can be securely stored, and made
unavailable to unauthorized users.
In addition to a high-performance cipher engine, the
OXUS931SE is complemented by robust authentication
solutions, including software password. A customizable
host application, the Oxford Semiconductor Authenticator,
is provided for both PCs and Mac hosts to:
o
o
o
Define and manage up to 10 passwords
Authenticate and mount the drive
Safely de-authenticate and unmount the drive.
