CHAPTER 11
S.E.C. CARTRIDGE MECHANICAL
SPECIFICATIONS
The Pentium II processor uses S.E.C. cartridge technology. The S.E.C. cartridge contains the
processor core, L2 cache and other passive components. The S.E.C. cartridge connects to the
motherboard through an edge connector. Mechanical specifications for the processor are
given in this section. See Section 1.2.1. for a complete terminology listing.
Figure 11-1 shows the thermal plate side view and the cover side view of the processor.
Figure 11-2 and Figure 11-3 show the S.E.C. Cartridge Top, Side, and Bottom Views.
Figure 11-4 through Figure 11-8 provide details of the Pentium II processor's thermal plate
and latch arms. Figure 11-9 through Figure 11-12 provide details of the Pentium II
processor's substrate and markings. The processor edge connector defined in this document
is referred to as the "Slot 1 connector."
Table 11-3 and Table 11-4 provide the processor edge finger and Slot 1 connector signal
definitions for the Pentium II processor. The signal locations on the Slot 1 edge connector are
to be used for signal routing, simulation and component placement on the motherboard.
11.1. S.E.C. CARTRIDGE MATERIALS INFORMATION
The S.E.C. cartridge is comprised of multiple pieces to make the complete assembly. This
section provides information relevant to the use and acceptance of the package. The complete
S.E.C. cartridge assembly weighs approximately 150 grams. See Table 11-1 for further piece
