Introduction
1.1 i960® RM/RN I/O Processor and IQ80960RM/RN FeaturesThe 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 Figure1-2.
•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
•I2C 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 66MHz (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, 3.3V 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 ToolsA number of software development tools are available for the i960® processor family1. This
manual provid e s in formation on two software de v el opment toolse ts: Wind River Sy ste m’s
Tornado* for I20* and Intel’s CTOOLS. If you are using other soft ware deve lopment tools, read
through the information in this chapter and in Chapter2 to gain a g eneral understanding of how to
use your tools with this board.
