SANTA CLARA, Calif. -- March 6, 2013

Renesas Electronics Corporation (TSE: 6723), a premier provider of advanced
semiconductor solutions, today announced the availability of its new
SuperSpeed Universal Serial Bus (USB 3.0) to Serial ATA (SATA) Revision 3
[Note] bridge SoC (system on chip, part number µPD720231) that enables the
reduction of the total BOM significantly. The uPD720231 enables effective
multi-gigabit per second (Gbps) data transfer between a USB 3.0 host system
and a SATA device used in widely adopted external USB hard drives and solid
state drives (SSD).

USB 3.0 technology delivers more than 10 times the data transfer performance
of the commonly used USB 2.0 peripheral interface. As the demand for media
storage capacities and data transfer speed increases, the uPD720231 offers a
fundamental building block to create an improved user experience for external
USB storage.

Renesas Electronics has played a leading role both in defining USB standards
and in developing USB technology. Renesas has enabled the USB 3.0 market by
releasing the µPD720200 USB 3.0 host controller to mass production in June
2009. Since then, the company’s lineup of USB 3.0 host controllers has been
widely adopted by customers worldwide. Total shipments of these products have
already exceeded 62 million units. In December 2009, the company also released
a UASP driver that further enhances the data transfer for storage devices by
improving the performance limit of the BOT (Bulk-Only Transfer) standard used
by USB 2.0, making it possible for external storage devices to take advantage
of the increased speed offered by the new USB 3.0 standard. To respond to the
need for even faster data transfer performance necessary with the increased
scale of the data in the storage device market, Renesas introduced the
µPD720230 bridge SoC and confirmed USB-IF certification in 2011.

The new µPD720231 device was developed to respond to the need to reduce the
number of components and to simplify printed circuit board (PCB) controller

Key features of the new µPD720231 SoC:

(1) Contributes to downsizing and power saving

Through integration, the new µPD720231 USB 3.0-SATA3 bridge SoC has reduced
the number of components by 40 percent compared with the number of other
commercial devices with equal functions. The µPD720231 features an embedded
voltage regulator and power-on reset circuit. The new product can store
firmware in SATA devices such as hard discs and SSD and can also omit external
serial flash ROM.

(2) Support for SATA Revision 3.0 enables 6 Gbps high-speed data transfer

The µPD720231 USB 3.0-SATA3 bridge SoC supports SuperSpeed USB transfer speeds
of up to 5 Gbps—as well as the SATA Revision 3.0 6Gbps bit rate achieving
maximum data transfer performance of USB 3.0. Thus, users can utilize actual
USB 3.0 transfer rate, free from the transfer speed of the SATA side.

(3) Supports high-speed UASP protocol, independent of OS

Renesas’ free UASP driver runs not only on the Renesas µPD720200 USB 3.0 host
controller and its follow-on products, the µPD720200A, µPD720201 and
µPD720202, but also on major chip sets with an embedded USB 3.0 host
controller, enabling higher data transfer speed on Windows XP/Vista/7. Renesas
licenses this driver from MediaLogic Corp.

The new µPD720231 device is compatible with Microsoft UASP drivers on Windows
8, and therefore does not depend on PC platform or OSs and can work in any
major environment with higher data transfer speed by UASP.

(4) Seamless connectivity with proven Physical Layer (PHY) core

Renesas’ USB 3.0 host controllers have provided the de facto USB 3.0
connection for various peripherals. The new µPD720231 bridge adopts the same
proven PHY core used in these host controllers, eliminating the unknown when
connecting to USB 3.0 hosts.

(5) Supports optical disc drive by ATAPI command support

The new µPD720231 device can control BD/DVD drives by supporting ATAPI
command. It facilitates design of BD/DVD drives with USB interface.


Mass production started in February 2013 and is expected to reach a scale of
500,000 units per month in June 2013. (Availability is subject to change
without notice.)

high-speed serial communication. It was developed for high data transfer rate
with mass storage devices such as hard-disk drives.
