Product Brief
SiI0680 System Diagram
SiI0680
The SiI0680 is a single-chip solution for designs
based on chipsets without an integrated ATA host
controller, or those requiring a greater number of
ATA channels to accommodate the growing num-
ber of storage peripherals with an ATA interface.
By simply adding a card with the SiI0680 and
loading the accompanying driver, any system with
a PCI bus interface may upgrade to the Ultra
ATA/133 interface.
The SiI0680 enables PC manufacturers to support
as many as four drives and incorporate the newest
drive standards—all at a lower cost. With the
SiI0680, other manufacturers, such as mother-
board, add-in card and embedded application
companies, can incorporate a cost-effective, hard
disk drive solution without sacrificing perform-
ance or flexibility.
For enhanced performance, the SiI0680 can be
packaged with Silicon Image’s robust Medley
ATA software RAID, which optimizes throughput
and data redundancy. Supporting RAID sets of up
to four hard disk drives, Medley enables RAID 0
Striping, RAID 1 Mirroring and RAID 0+1
Mirrored Striping.
