Silicon Image Launches SteelVine® Series 3 Core Storage Processor and SATA Port Multiplier

New Generation Products Feature Dramatically Faster Processing, Lower Power
Consumption, and Significantly Reduced Motherboard RAID Solution Cost
TAIPEI, Taiwan--(Business Wire)--
Silicon Image, Inc. (NASDAQ:SIMG), a leader in semiconductors and intellectual
property for the secure distribution, presentation and storage of
high-definition (HD) content, today announced the introduction of the SiI5923
SteelVine® Series 3 Core storage processor and the SiI3723 SteelVine Series 3
Core SATA 1:2 port multiplier-further expanding the company`s proven SteelVine
storage product portfolio. Key applications for these new single-chip solutions
include personal computers (PCs), digital video recorder (DVRs) and consumer
electronics (CE) motherboards, as well as storage enclosures. SteelVine Series 3
Core product samples will be available in June 2009 with volume shipments
starting in August 2009.

SteelVine Series 3 Core products are designed for enhanced performance and
system-level cost reduction without sacrificing functionality. SteelVine Series
3 Core storage processors perform 38 percent faster and consume 33 percent less
power compared to the previous generation of SteelVine products. In addition,
the bill of material for the SteelVine Series 3 Core storage processor is
one-half compared to its predecessor. Silicon Image has achieved this cost
reduction through integration of external components and size reduction; the
form factor of this new single chip has also been reduced by 64 percent from an
88-pin QFN to a 40-pin QFN. Silicon Image achieved these benefits while
maintaining the key features of the previous generation SteelVine storage
processors, such as ease of use and 100 percent hardware RAID.

SteelVine Series 3 Core products offer key differentiating features that
customers demand. The SiI5923 SteelVine Series 3 Core storage processor offers
an easy software path, enabling motherboard manufacturers to circumvent cryptic
BIOS configuration screens and multiple windows drivers. In addition, the
SiI5923 SteelVine Series 3 Core storage processor features Silicon Image`s
performance RAID, which allows users to easily speed up or add automatic backup
features, adding additional drives as needed. The SiI3723 SteelVine Series 3
Core SATA 1:2 port multiplier supports host and device rates of 1.5 Gbps or 3
Gbps with auto-negotiation, giving system designers and end users SATA hard disk
drive flexibility.

"Silicon Image has a history of pioneering successful and innovative storage
solutions for PCs and consumer electronics, and we continue this tradition with
the unique architecture featured in the new SteelVine Series 3 Core products,"
said Conrad A. Maxwell, senior product line marketing manager at Silicon Image,
Inc. "Our collaboration with leading motherboard manufacturers enables us to
deliver advanced storage solutions optimized for faster processing capabilities,
lower power consumption and reduced cost."

Key features of the SiI5923 SteelVine Series 3 Core storage processor include:

* Storage offload engine (100 percent)
* eSATA-capable device ports
* RAID 1 performance (racing)
* RAID 0 low latency (high performance)
* Easy to use auto mirror/failover (automatic sector recovery)
* High-performance hardware acceleration

Key features of the SiI3723 SteelVine Series 3 Core SATA port multiplier
include:

* One host and two device ports
* Storage SATA port multiplier
* eSATA compatible device ports
* Automatic down shift to Gen 1
* LED pins for each PHY
* Enhanced performance option
