3.2 System Architecture
The following illustration of block diagram illustrated basic design reference of PPAP-3710L-
0200, a highly integrated system solution. The most up-to-date system architecture of PPAP-
3710L-0200 includes two main VLSI chips. It contains CMIC-SL and CSB5 to support mPGA
Celeron/Pentium 4 processor, DIMM, PCI bus interface, USB port, SMBus communication, and
Ultra DMA/100 IDE Master. The on-board CSB5 chip supports two UARTs, and hardware
monitoring.
PPAP-3710L-0200 has built-in Socket 478 to support Intel mPGA Celeron/Pentium 4 processor
(400 or 533MHz FSB) for cost-effective and high performance application.
The CMIC-SL provides a completely integrated solution for the system controller and data path
components in a Celeron/Pentium 4 processor system. It provides optimized 64-bit DDRAM
interface with one 184 pin 2.5V DIMM.
The CSB5 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 two 32-bit PCI bus interfaces.
All detailed operating relations are shown in
