1 Introduction
In this document when a reference is made to the processor and/or the Intel
®
Pentium
®
4 processor
in the 478-pin package, it is intended that this includes the Intel
®
Pentium
®
4 processor in the 478-
pin package, and the Intel
®
Pentium
®
4 processor with 512-KB L2 cache on 0.13 micron process.
Where a reference is intended to refer to a specific processor, the specific processors will be listed
separately.
This design guide supports the following processors:
• Intel
®
Pentium
®
4 processor in the 478-pin package
• Intel
®
Pentium
®
4 processor with 512-KB L2 cache on 0.13 micron process
This design guide documents Intel’s design recommendations for systems based on the Pentium 4
processor in the 478-pin package with the Intel
®
850 chipset family, which consists of the Intel
®
82850 (MCH) and the Intel
®
82801BA (ICH2), or the Intel
®
82850E (MCH) and the Intel
®
82801BA (ICH2). Unless otherwise specified, references to the 850 chipset, 850 MCH, 850
system, or 850 platform refer to both the 82850 and the 82850E chipset. Specific design
considerations for 300 MHz /400 MHz Rambus RDRAM* technology versus 533 MHz RDRAM
technology are documented separately as required. Design issues such as thermal considerations
should be addressed using specific design guides or applications notes for the processor and 850
chipset.
Carefully follow the design information, board schematics, and debug recommendations presented
in this document. 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 categories below.
• Design Recommendations are items based on Intel’s simulations and lab experience to date
and are strongly recommended, if not necessary, to meet the 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 an example, but may not be applicable to particular designs.
Note: The guidelines recommended in this document are based on experience and simulation work done
at Intel while developing the processor and 850 chipset based systems.
Platform schematics are shown in Appendix A, and are intended as 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 system board options. Additional flexibility is possible through
other permutations of these options and components.
