SYSTEM OVERVIEW
The Apollo PLE133 chipset consists of the VT8601A North Bridge (described by this document) and the VT82C686B South
Bridge (described in a separate data sheet). The VT8601A is a PC system logic North Bridge for Socket-370 CPUs with
integrated 2D/3D Graphics accelerator. The core logic portion of the chip is based on the VIA Apollo Pro133 with integrated
graphics accelerator provided by an industry leading Graphics supplier. The combination of the two leading edge technologies
provides a stable, cost-effective, and high performance solution to both the Desktop and Mobile personal computer markets. As
shown in Figure 1 below, the Apollo PLE133 will interface to:
Socket-370 Front-Side Bus (133, 100 and 66 MHz)
PC133 / PC100 SDRAM Memory Interface
PCI Bus (33 MHz)
Analog RGB Monitor with DDC
