The OXUF943SE is a high performance, low power storage controller optimized for
secure personal storage applications, bridging between FireWire 800 or USB 2.0
interface to a single SATA hard disk.
Optimized for bus-powered applications, the OXUF943SE supports a number of power
saving modes, including SATA Interface Power Management (IPM), which allows
additional power saving when connected to an HDD that also supports IPM.
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 USB 2.0 device, a FireWire 800 link layer, and a SATA host controller, the
OXUF943SE enables designers to create products with a minimal number of external
components and a low cost BOM.
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 USB 2.0 PHY supports both full and high speed, using bulk-only
transport Mass Storage Class device protocol. OXUF943SE’s 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.
FireWire
The embedded 1394 PHY and link layer supports FireWire 800, is backward compatible
with FireWire 400 and complies with the 1394-1995 and 1394-2000 specifications. No
additional 1394 host drivers are required for either Windows or Mac operating systems
for standard storage applications.
SATA Interface
The embedded 3 GHz SATA host interfaces supports the latest revisions of the SATA II
specifications. Interface speeds of 3 GHz and 1.5 GHz deliver maximum performance
with minimum latency for external SATA storage.

OXUF943SE, FireWire 800 or USB 2.0 to SATA Controller with Encryption
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.
The cipher engine can be configured for the following AES
algorithms:
o
ECB – Electronic Code Book
-
Simplest implementation of the AES algorithm
-
Fully NIST / FIPS140-2 approved algorithm
CBC – Cipher Block Chaining
-
Feeds forward encrypted data to produce a stronger
cipher-text result than ECB
-
Fully NIST / FIPS140-2 approved algorithm
XTS – XEX-based Tweaked CodeBook with CipherText
Stealing
-
Variant of AES developed for protecting data at rest,
also known as IEEE P1619
Development Support
For external Mac and PC storage solutions, PLX Technology
offers a comprehensive support package including:
o
o
o
o
Reference designs comprising both hardware and software
components
Evaluation boards with pre-built application firmware
Software Development Kit (SDK) comprising source code
and debug boards
Extensive range of application notes to shorten learning
curves and simplify implementation
