Pentium
II Processor at 350 MHz, 400 MHz, and 450 MHz
Datasheet
9
Extended Thermal Plate
—This S.E.C.C. 100 MHz processor feature is the surface used to
attach a heatsink or other thermal solution to the processor. The extended thermal plate has an
extended skirt as compared to the 66 MHz Pentium II processors for increased thermal
capabilities.
Cover
—The plastic casing that covers the backsire of the substrate and holds processor
branding and marking information.
Latch arms
—An S.E.C.C. processor feature which can be used as a means for securing the
processor in the retention mechanism(s).
PLGA
- Plastic Land Grid Array. This package technology incorporates a heat slug within the
package that contacts the extended thermal plate.
OLGA
- Organic Land Grid Array. This package technology permits attaching the heatsink
directly to the die.
Additional terms referred to in this and other related documentation:
SC 242
—The 242-contact slot connector (previously referred to as Slot 1 connector) that the
S.E.C.C. and S.E.C.C.2 plug into, just as the Pentium
Pro processor uses Socket 8.
Retention mechanism
—An enabled mechanical piece which holds the S.E.C. cartridge in the
SC 242 connector.
Heatsink support
—The support pieces that are mounted on the motherboard to provide added
support for heatsinks.
The L2 cache (TagRAM, BSRAM) die keep industry names.
