VIA VT8237 South Bridge

Introduction: Bringing Serial ATA and RAID to the Mainstream

The new VIA VT8237 South Bridge brings for the first time the latest high

performance storage technologies to the Mainstream PC. Previously confined to the

niche enthusiast and enterprise segments, Serial ATA and Serial RAID can now be

enabled on a complete range of VIA core logic chipset platforms supporting the full

spectrum of Intel® Pentium® 4, AMD Athlon™ XP, AMD Opteron™, and VIA

C3™/Eden™ ESP processors.

Featuring the new VIA DriveStation™ Controller Suite, the VT8237 enables multiple

drive connectivity options and native support for Serial ATA and Serial RAID,

alongside more traditional South Bridge functions such as IDE and PCI. In addition,

the VT8237 delivers exceptional surround sound capabilities through its support for

VIA Vinyl and high-resolution VIA Vinyl Gold Audio, and also offers a host of high-

bandwidth connectivity options, including support for up to eight high-speed USB 2.0

ports and high-throughput 10/100Mb/s Ethernet.

Based on VIA’s unique V-MAP (VIA Modular Architecture Platform) architecture, the

VT8237 features the new Ultra V-Link bus, which delivers data throughput speeds of

up to 1066MB/sec from the South Bridge to the emerging new generation of high

performance VIA North Bridge solutions. Through its support for the 8X V-Link

interface, the VT8237 is also fully compatible with existing VIA North Bridge solutions

such as the KT600 and PT800, giving OEMs and motherboard manufacturers

unprecedented flexibility in integrating new levels of advanced I/O functionality into

platform design.

The VT8237 South Bridge has been designed to meet the increasing demands of

today’s software programs while providing all the necessary headroom for the data-

intensive applications of tomorrow. It consists of four key components, as shown in

Figure 1 and listed below.
