Product Brief
SteelVine^® Series 3 Core
Third Generation SATA-to-Dual eSATA Storage Processor
The SteelVine^® Series 3 Core storage processor is a low-cost, single chip solution
designed to be built into PC motherboards, DVRs and consumer electronics devices. It
features a 3Gbps SATA host interface and two eSATA capable device ports. The SiI5923
features Silicon Image performance RAID, which allows users to easily speed up or add
automatic back up by adding additional drives as needed.
The SteelVine Series 3 Core storage processor
extends the capabilities of PC motherboards,
DVR devices, and consumer electronics by
adding eSATA and advanced storage features on
a single chip that easily integrates with existing
designs via a SATA connection.
Advanced features include enhanced sector
recovery and automatic data repair to provide
higher levels of protection for your customer’s
critical data. Management parameters can be
customized using the Manufacturing Utility or
through customer applications built using the
SiI5923 Software Development Kit.
SiI5923 storage processor supports JBOD and
the following RAID modes: FAST (RAID 0) and
SAFE (RAID 1). RAID mode configuration can
be accomplished through a System Management
Bus (SMBus)-based GUI or strap pins for true
software-free implementation.
The SiI5923 reduces your power budget by
entering aggressive power-down modes when
drive(s) are idle or not present.
The economical 40-pin QFN package offers a
small footprint implementation.
