1 Overview
This datasheet provides Intel’s specifications for the Intel
®
852PM and Intel
®
852GME chipset
based systems.
The Intel
®
852PM chipset MCH is designed for use with the Mobile Intel
®
Pentium
®
4 processor,
Mobile Intel
®
Pentium
®
4 Processor supporting Hyper-Threading Technology on 90-nm process
technology, Intel
®
Celeron
®
processor or the Intel
®
Celeron
®
D processor on 90 nm process and
in the 478-pin package. The Intel MCH manages the flow of information between its five
interfaces: the system bus interface, the system memory interface, the AGP interface, and the hub
interface.
The Intel
®
852GME chipset GMCH is designed for use with the Mobile Intel Pentium 4
processor, Mobile Intel Pentium 4 processor supporting Hyper-Threading Technology on 90-nm
process technology, Intel Celeron processor or the Intel
®
Celeron
®
D processor on 90 nm process
and in the 478-pin package. The GMCH manages the flow of information between its seven
interfaces: the system bus interface, the system memory interface, the analog VGA port, the
DVOB and C interfaces, the hub interface, and the LVDS panel interface.
All recommendations will apply to all platforms unless specified. Any references to GMCH apply
to both platforms unless otherwise specified. Any references to Mobile Intel Pentium 4 processor
also applies to Mobile Intel Pentium 4 processor supporting Hyper-Threading Technology on 90-
nm process technology unless specified. Any references to the Intel Celeron processor also apply
to the Intel Celeron D processor on 90 nm process and in the 478-pin package unless specified.
