14 Design Guide

1. Introduction

This design guide provides Intel’s design recommendations for systems based on the Mobile Intel

Pentium

4 Processor-M and the Intel

845MP/845MZ chipset. Design issues such as thermal

considerations should be addressed using specific design guides or application notes for the processor or

845MP/845MZ chipset.

These design guidelines have been developed to ensure maximum flexibility for board designers while

reducing the risk of board related issues. The design information provided in this document falls into one

of the two following categories.

• Design Recommendations are items based on Intel’s simulations and lab experience to date and are

strongly recommended, if not necessary, to meet timing and signal quality specifications.

• Design Considerations are suggestions for platform design that provide one way to meet the design

recommendations. They are based on the reference platforms designed by Intel. They should be

used as examples, but may not be applicable to particular designs.

Note: The guidelines recommended in this document are based on experience and preliminary simulation work

performed at Intel while developing Mobile Intel Pentium 4 Processor-M and 845MP/845MZ chipset-

based systems. This work is ongoing, and the recommendations and considerations are subject to change.

Platform schematics are provided in Section 13. The schematics are a reference for board designers.

While the schematics may cover a specific design, the core schematics will remain the same for most

platforms. The schematic set provides a reference schematic for each platform, component as well as

common motherboard options. Additional flexibility is possible through other permutations of these

options and components.
