System Architecture
The following block diagram illustrates how the PCI-953 single board computer provides a highly
integrated system solution. The system architecture of the PCI-953 single board computer
includes two main VLSI chips, the Intel 875P MCH and Intel 6300ESB ICH to support a Pentium 4
processor with a front side bus (FSB) up to 800MHz, DDR-400 SDRAM, PCI and PCI-X bus
interfaces, advanced power management (APM), ACPI-complaint power managment, SMBus
communication, SATA, and Ultra DMA/33/66/100 IDE Bus Master. The on-board super I/O chip,
LPC47B27X, supports a PS/2 keyboard/mouse, two UARTs (16550 compatible), and floppy drives.
In addition, the two on-board gigabit Ethernet devices provide the user with additional
flexibility and reliability.
The Intel 875 (Canterwood) Memory Controller Hub (MCH) provides a 64-bit AGTL+ based host
bus interface, optimized 128-bit DRAM interface supporting two DDR-400 DIMMs at the
maximum bus frequency of 400MHz. The 8Mbit non-volatile Flash memory supports the ability to
Write Protect Flash under BIOS control. The 64-bit PCI-X bus interface supports 32-bit and 64-bit
PCI at 33/66MHz.
The Intel 6300ESB ICH employs the Accelerated Controller Hub architecture which makes a direct
connection from the memory to IDE controllers. It supports 2-channel dedicated Ultra DMA-33/
66/100 IDE master interfaces, full Plug-and-Play compatibility, Advanced Programmable
Interrupt Controller (APIC) interface, and internal real-time clock (RTC) to maintain the time and
date of a system. It also supports dual-port USB-2.0 and PCI 2.2 Compliance operation. The Hub
fully supports Operating System Directed Power Management via the Advanced Configuration
and Power Interface (ACPI) specification.
The Super I/O chip LPC47B27X integrates two high speed serial ports, a FDD interface, and an
8042 keyboard controller with a PS/2 mouse port.
In addition, an advanced feature is used on the PCI-953 single board computer to support
detection and monitoring of the system temperature, operating voltage, and fan status.
There are two on-board PCI gigabit Ethernet devices via RJ-45 ports hard-mounted to the board
bracket.
All of the details of operating relations are shown in the “System Block Diagram” on the
following page.
