Intel® IQ31244 Customer Reference Board

1.0Introduction

The Intel® IQ31244 Customer Reference Board (hereafter called “IQ31244”) is a FlexATX motherboard based on the Intel® 80321 I/O Processor. The Intel® third-party part number for this motherboard is MB-701.

This platform is capable of operating at a maximum of 100 MHz PCI-X on both the secondary and primary PCI buses (refer to Figure 1). The IQ31244 features Intel® 31244 PCI-X to Serial ATA Controllers on the secondary side of an Intel® 31154 133 MHz PCI Bridge. The IQ31244 also includes an Intel® 82546 Dual-Port Gigabit Ethernet Controller, a 64-bit PCI-X expansion slot, and various features on the 80321 peripheral bus interface (PBI). The Intel® 31154 133 MHz PCI Bridge provides a PCI-X bridge, which allows direct peer-to-peer communication between the processor and the four 31244 PCI-X to Serial ATA Controllers on the secondary PCI-X 64-bit bus with frequency of 100 MHz. The IQ31244 provides sixteen Serial ATA connectors, since each Serial ATA has four SATA channels. The Intel® 82546EB Dual-Port Gigabit Ethernet Controller interface has two network ports. The Intel® 80321 I/O Processor also provides the DDR SDRAM memory controller. The IQ31244 processor peripheral bus interface operates at a frequency of 33 MHz frequency with flash ROM, CompactFlash*, UART, Hex Display LEDs, and rotary switch.

A block diagram of IQ31244 is shown in Figure 1.
