3 Pinout Specifications
This chapter describes the Itanium 2 processor signals and pinout.
Note: The pins labeled “N/C” must remain unconnected. The Itanium 2 processor uses a JEDEC standard
pin naming convention.
In this chapter, pin names are the actual names given to each physical pin of the processor.
System bus signal names are the names associated with the functions of those pins. For those pins
associated with multiple functions, their pin names and system bus signal names are not
necessarily identical.
Figure 3-1 shows the Itanium 2 processor pin location diagram from the top view.
