12 Ballout and Package Information

This chapter provides the ballout and package information.

12.1 Ballout

Figure 12-1 and Figure 12-2 show the 82925X/82925XE MCH ballout as viewed from the top

side of the package. Table 12-1 provides the MCH ballout sorted by signal name and Table 12-2

provides the MCH ballout sorted by ball number.

Note: Balls that are listed as RSV are reserved. Board traces should be routed to these balls.

Note: Balls that are listed as NC are No Connects.
