OXUF943SE, FireWire 800 or USB 2.0 to SATA Controller with Encryption
OXUF943SE Highlights
The OXUF943SE is a high performance, low power storage controller optimized for
secure personal storage applications, bridging between FireWire800 or USB2.0
interface to a single SATA hard disk.
General Features
o High performance, low power
SATA storage controller with
Encryption
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.
Key Features
o High performance, low power
SATA storage controller with
Encryption
o Integrated 480Mbps USB2.0 high
speed core and PHY
o Market proven 1394b PHY
interface and Link Layer with
industry leading performance
- Supports PHY power down
modes
o Integrated SATA II compliant core
and PHY
- Supports 3.0Gbps and 1.5Gbps
interfaces
- Supports Interface Power
Management (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.
o Integrated hardware cipher engine
supporting AES-128 encryption /
decryption (over USB and
FireWire):
- Support for AES-ECB and AES-
CBC algorithms
- Support for AES-XTS as defined
by IEEE P1619
- Host software and driver
supplied for password
Integrating a USB2.0 device, a FireWire800 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.
application for PC and Mac
o SPI interface for serial flash
o 19 GPIOs allow easy product
customization
o Support for USB Human Interface
Device (HID)
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.
o Support for button push apps
FireWire
The embedded 1394 PHY and link layer supports FW800, is backward compatible with
FireWire400 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 3GHz SATA host interfaces supports the latest revisions of the SATA II
specifications. Interface speeds of 3GHz and 1.5GHz deliver maximum performance with
minimum latency for external SATA storage.
