VIA Technologies Chipsets for P6-Class Processors
Apollo Pro
The Apollo Pro is a high-performance chipset for Slot 1 mobile and desktop PC systems; it can also
support the Socket 8 Pentium Pro processor. The Apollo Pro includes support for advanced system
power management capability for both desktop and mobile PC applications, PC100 SDRAM, AGP 2x
mode, and multiple CPU/DRAM timing configurations. The Apollo Pro chipset is comparable in features to the 440BX and PIIX4e chipsets from Intel and represents one of the first non-Intel chipsets to
support the Socket 1 architecture.
The VIA Apollo Pro consists of two devices—the VT82C691 North Bridge chip and the VT82C596, a
BGA-packaged South Bridge with a full set of mobile, power-management features. For cost-effective
desktop designs, the VT82C691 can also be configured with the VT82C586B South Bridge.
The VT82C691 Apollo Pro North Bridge supports all Slot 1 (Intel Pentium II) and Socket 8 (Intel
Pentium Pro) processors. The Apollo Pro also supports the 66MHz external bus speed and the newer
100MHz CPU external bus speed required by the 350MHz and faster Pentium II processors. AGP v1.0
and PCI 2.1 are also supported, as are FPM, EDO, and SDRAM. Various DRAM types can be used in
mixed combinations in up to eight banks and up to 1GB of DRAM. EDO memory timing is 5-2-2-2-22-2-2 for back-to-back accesses, and SDRAM timing is 6-1-1-1-2-1-1-1 for back-to-back accesses.
The VT82C596 South Bridge supports both ACPI and APM and includes an integrated USB controller
and dual Ultra DMA-33 ATA ports.

ProSavage PM133
The VIA ProSavage PM133 integrates S3 Graphics’ S3 Savage 4 and S3 Savage 2000 3D and 2D graphics engines with the Apollo Pro 133A chipset. The major features of the chipset are the same as for the
Apollo Pro 133A, with the following additions:
■ 2MB–32MB shared memory architecture integrated with Savage 4 3D and Savage 2000 2D video
■ Z-buffering, 32-bit true-color rendering, massive 2K-by-2K textures, single-pass multiple textures, sprite antialiasing, and other 3D features
■ Support for DVD playback, DVI LCD displays, and TV-out
An optional AGP 4x interface allows the integrated AGP 4x video to be upgraded with an add-on card
if desired. This two-chip set consists of the VT8605 North Bridge and VT8231 South Bridge.
The VT8231 South Bridge integrates the Super I/O and supports the LPC interface.

Apollo Pro266
The VIA Apollo Pro266 is a high-performance North/South Bridge chipset designed to support Socket
370 processors, including the Pentium III, Celeron, and VIA’s own C3. The Apollo Pro 266 is the first
chipset from VIA to replace the traditional PCI (133MBps) connection between North and South
Bridge chips with VIA’s 4x V-Link interconnect, which runs at 266MBps.
Features of the Apollo Pro266 include
■ AGP 2x/4x graphics bus support
■ Integrated MC’97 modem
■ 133/100/66MHz processor bus support
■ Integrated 10/100BASE-T Ethernet and
1/10MHz Home PNA networking
■ PC-100/133 SDRAM and PC200/266
DDR SDRAM memory interface
■ Hardware monitoring
■ ATA-100 IDE interface
■ ACPI/On Now! Power management
■ Support for six USB ports
■ VIA 4x (266MBps) V-Link North/South
Bridge interconnect
■ Integrated AC97 six-channel audio
The VIA Apollo Pro266 chipset is a two-chip set consisting of the 552-pin BGA VT8633 North Bridge
controller and the 376-pin BGA VT8233 South Bridge controller. The Apollo Pro266T is an updated
version of this chipset that supports Pentium III Tualatin processors.
Because of the V-Link high-speed interconnect between the North Bridge and South Bridge, PCI is
managed by the South Bridge. This is similar to the way in which Intel hub architecture works, and
this basic architecture has been followed by all subsequent VIA chipsets that use V-Link architecture.
Silicon Integrated Systems Chipsets for P6-Class Processors
SiS630 Family
The SiS630 is a high-performance, low-cost, single-chip set with integrated 2D/3D graphics and support for processors such as the Pentium III, Celeron, and Cyrix III/VIA C3.
The integrated video is based on a 128-bit graphic display interface with AGP 4x performance. In addition
to providing a standard analog interface for CRT monitors, the SiS630 also provides the digital flat panel
port (DFP) for a digital flat panel monitor. An optional SiS301 video bridge supports NTSC/PAL TV output.
The SiS630 also includes integrated 10/100Mb Fast Ethernet, as well as an AC97-compliant interface that
comprises a digital audio engine with 3D-hardware accelerator, on-chip sample rate converter, and professional wavetable along with a separate modem DMA controller. SiS630 also incorporates the LPC
interface for attaching newer Super I/O chips and a dual USB host controller with five USB ports.
Features of the SiS630 include the following:
■ Support for Intel/AMD/Cyrix/IDT
Pentium CPU processor bus at
66/83/90/95/100/133MHz
■ Integrated AGP 2x 2D/3D video/graphics
accelerator

modem
■ Integrated keyboard/mouse controller
■ Meets ACPI 1.0 requirements
■ Integrated 10/100Mbps Ethernet controller
■ PCI Bus Power Management Interface
Spec. 1.0

■ Dual USB controller with five USB ports
The SiS630E chip is almost identical in its feature set but doesn’t support the secondary CRT controller (also called the video bridge). The SiS630S chip adds support for an AGP slot and the new
Advanced Communication Riser to the basic SiS630 features. The SiS630ET and SiS630ST chips add
support for the Tualatin 0.13 micron Pentium III and Celeron III processors.
What’s really amazing about the SiS630 family is that all these features are combined into a single
chip that’s not much larger than the North Bridge used by other chipsets.
These chipsets have been discontinued.
SiS633/635 Family
The SiS633/635 family is a series of high-performance single-chip chipsets that support the Pentium
III and Celeron Socket 370 processors. T-series chipsets also support the newer .13-micron Pentium III
Tualatin processors released in May 2001.
The SiS633 and SiS633T chipsets support PC133 SDRAM, whereas the SiS635 and SiS635T chipsets
support PC133 SDRAM, DDR266 DDR SDRAM, or a mixture of PC133 and DDR266 SDRAM. All
chipsets in the family support the following features:
■ Integrated 4x AGP
■ 1.5GB RAM
■ Up to six PCI masters
■ Six USB ports
■ UDMA/100 IDE host adapters
■ AC97 audio and AMR support
SiS635/635T also support ACR or CNR riser technology and integrate 10/100BASE-T Ethernet and
1/10MHz Home PNA networking.
These chips use a 677-pin BGA package.
The 633/635 family has been discontinued, and it appears that very few motherboards were built
using these chipsets.
SiS620/5595
The SiS620/5595 is a North/South Bridge chipset with integrated video that supports Slot 1 or Socket
370 processors.
Features include the following:
■ 66/100MHz processor bus
