3.2 System
Architecture
The following illustration of block diagram will show you how PPAP-200 gives you a highly
integrated system solution. The most up-to-date system architecture of PPAP-200 includes two
main VLSI chips. It contains 82815GMCH and 82801BA ICH2 to support FC-PGA
Celeron/Pentium III processor, SODIMM, PCI bus interface, USB port, SMBus communication,
and Ultra DMA/100 IDE Master. The on-board super I/O chip Winbond W83627HF supports two
UARTs, FDC, parallel port and hardware monitoring.
PPAP-200 has built-in Socket 370 to support Intel FC-PGA Celeron/Pentium III processor (66,
100 or 133MHz system bus) for cost-effective and high performance application. However, the
FC-PGA Coppermine-256 (Pentium III) processor provides twice the Celeron L2 Cache.
The 82815 GMCH provides a completely integrated solution for the system controller and data
path components in a Celeron/Pentium III processor system. It provides optimized 64-bit DRAM
interface with one 144 pin 3.3V DIMM.
The 82801BA ICH2 provides a highly integrated multifunction for the best industry applications.
It supports 2-channel dedicated Ultra ATA/33/66/100 IDE master interface, Universal Serial Bus
(USB)
controllers and one 32-bit PCI bus interface.
All detailed operating relations are shown in
