GENERAL DESCRIPTION
The SMSC VictoryBX-66 chipset provides features necessary to optimize the performance of Pentium II and
Pentium IIl based mobile and desktop PC systems. The VictoryBX-66 is comprised of the Intel FW82443BX
Memory Controller (North Bridge) and the SMSC Victory66 SLC90E66 I/O Controller (South Bridge). A PC designed
with the VictoryBX-66 Chipset benefits from the performance provided by the 440BX North Bridge and the added
value of the SMSC Victory66 South Bridge. The VictoryBX-66 chipset can be used in existing designs utilizing the
Intel 440BX Chipset.
Intel 440BX North Bridge Performance
The VictoryBX-66 chipset includes the Intel 440BX Northbridge providing system designers with proven
performance, reliability, and stability. Primary interfaces of the Intel FW82443BX are the 100-MHz Processor
Interface (Front Side Bus), Accelerated Graphics Port (AGP) 1.0 (1x/2x) interface, 64-bit PC100 SDRAM interface,
and PCI Host Interface. The 100-Mhz Front Side Bus coupled with the AGP 2x and PC100 SDRAM performance
provide a properly balanced architecture for optimal processor and graphics performance.
SMSC Victory66 SLC90E66 South Bridge Offers Enhanced Value
The Victory66 South Bridge offers numerous enhancements that provide increased performance and power
management functionality. The integrated Ultra ATA/66 IDE Controller supports hard drive data transfer of up to 66
Million bytes per second twice the bandwidth of other Southbridges. The Open Host Controller Interface (OHCI)
compatible Universal Serial Bus (USB) Host Controller Architecture provides increased data throughput
performance. Additionally, power management enhancements make the VictoryBX-66 Chipset ideal for high-
performance mobile designs.
Supports Existing Designs
Because the VictoryBX-66 Chipset is comprised of the Intel FW82443BX North Bridge and the PIIX4E-compatible
Victory66 South Bridge, the VictoryBX-66 can be used in existing designs to enhance performance and provide
improved power management. BIOS support for the VictoryBX-66 chipset is available from all major BIOS vendors.
Optimized for Mobile Applications
The VictoryBX-66 Chipset is the optimum solution for advanced mobile applications. The Intel FW82443BX
provides leading edge notebook performance with its AGP 1.0 graphics interface, PC100 SDRAM support and 100-
/66-MHz front side bus support. The Victory66 SLC90E66 South Bridge provides best of class performance with its
Ultra ATA/66 IDE Controller and OHCI USB Host Controller. Power management enhancements improve the
power profile of systems based on the VictoryBX-66. The ability to disable and/or relocate the Real Time Clock
allows for superior performance when used with highly integrated SMSC System Controller Hubs such as the
FDC37N972 with integrated 8051 power management controller. The ability to wake from USB Power-On Suspend
provides additional system usability.
