6300ESB ICH Embedded Platform Design Guide
Introduction
Introduction 1
This design guide provides Intel's design recommendations for systems based on the Intel
®
Pentium M
®
Processor, Intel
®
Pentium
®
M Processor on 90 nm process with 2 MB L2 cache, or
Intel
®
Celeron M Processor using the Intel
®
855GME Chipset and Intel
®
6300 ESB I/O Controller
Hub. These design guidelines have been developed to ensure maximum flexibility for board
designers while reducing the risk of board-related issues.
The Intel reference schematics located at the end of this document may be used as a reference for
board designers. While the schematics shall cover specific designs, the core schematics remain the
same for most Intel
®
855GME/6300ESB I/O Controller Hub chipset platforms.
The Pentium M/Celeron M processor in the 478-pin or 479-BGA package with the Intel 855GME/
6300ESB I/O controller hub chipset delivers a high-performance embedded platform solution. The
processor and chipset support a 400 MHz source synchronous Pentium M/Celeron M processor
system bus using a split-transaction, deferred-reply protocol. Table 1 presents conventions and
terminology used in this document.
Note: Unless otherwise noted, all design considerations for the Intel Pentium M Processor may also be
used for the Intel Pentium M Processor on 90 nm process with 2 MB L2 cache, or the Intel Celeron
M Processor. Refer to the Intel

Pentium
®
M Processor Datasheet, Intel
®
Pentium
®
M Processor
on 90 nm process with 2 MB L2 cache Datasheet, and the Intel
®
Celeron
®
M Processor Datasheet
for detailed processor information.
