Introduction
WAFER-E668EV ATX/AT main board is a high-performance
computer mainboard based on the VIA
®
TwisterT PN133T
VT8606 and VT8231 chipset. It is designed with VIA
®
EDEN
processor, making it ideal for the cost-effective CPU board
markets.
The VIA
®
TwisterT PN133T (VT8606) is a VIA
®
EDEN
processor system logic north bridge with the addition of 133
MHz capability for both the CPU and SDRAM interfaces. VIA
®
TwisterT PN133T may be used to implement both desktop and
notebook personal computer systems from 100MHz to 133MHz
based on EDEN (EBGA packing). The primary features of the
VIA
®
TwisterT PN133T-North Bridge are: VIA
®
EDEN CPU
(Front Side Bus) Interface (100 / 133MHz), SDRAM Memory
Interface (100 / 133MHz), 32-bit PCI with Integrated 2D / 3D
graphics accelerator.
The VT8231 PSIPC (PCI Super-I/O Integrated Peripheral
Controller) is a high integration, high performance, power-
efficient, and high compatibility device that supports both Intel
and non-Intel based processors to PCI bus bridge functionality,
ensuring a complete Microsoft PC99-compliant PCI system.
