Introduction
1.1 i960
®
RM/RN I/O Processor and IQ80960RM/RN
Features
The i960 RM/RN I/O processor serves as the main component of a high performance, PCI-based
intelligent I/O subsystem. The IQ80960RM and IQ80960RN platforms allow the developer to
connect PCI devices to the i960 RM/RN I/O processors using the four secondary PCI expansion
connectors. The features of the IQ80960RM and IQ80960RN platforms are enumerated below and
shown in
Figure 1-1 and Figure 1-2 .
• i960 RM/RN I/O processor
• Modified PCI long-card form factor
• 64-bit or 32-bit primary PCI bus interface (80960RM 32-bit only)
• 64-bit or 32-bit secondary PCI bus connected to the primary PCI interface with a PCI-to-PCI
bridge (80960RM 32-bit only)
• DMA channels on both PCI buses
• I 2 C Serial Bus
• 168-pin, 3.3V DIMM socket supporting 16 to 128 Mbytes of Synchronous DRAM organized
x72 to support Error Correction Code (ECC) and clocked at 66 MHz (ships with 16 M/ECC
installed)
• Serial console port based on 16C550 UART
• Eight user-programmable LEDs
• 3 Indicator LEDs: processor has passed self-test, 3.3 V is supplied to SDRAM, and 3.3 V is
supplied to secondary PCI slots
• Flash ROM, 2 Mbytes
• Logic analyzer connectors for SDRAM bus, ROM bus and secondary PCI arbitration signals
• Fan heatsink monitor circuit
• Battery backup for SDRAM
• JTAG header
1.2 Software Development Tools
A number of software development tools are available for the i960

0* and Intel’s CTOOLS. If you are using other software development tools, read
through the information in this chapter and in Chapter 2 to gain a general understanding of how to
use your tools with this board.
