Introduction

1Introduction

The Intel®Pentium®4 processor on 90 nm process is a follow on to the Intel®Pentium®4

processor in the 478-pin package with enhancements to the Intel NetBurst®microarchitecture. The

Pentium 4 processor on 90 nm process uses Flip-Chip Pin Grid Array (FC-mPGA4) package

technology, and plugs into a 478-pin surface mount, Zero Insertion Force (ZIF) socket, referred to

as the mPGA478B socket. The Pentium 4 processor on 90 nm process, like its predecessor, the

Pentium 4 processor in the 478-pin package, is based on the same Intel 32-bit microarchitecture

and maintains the tradition of compatibility with IA-32 software.

Note: In this document the Pentium 4 processor on 90 nm process is also referred to as the processor.

The Pentium 4 processor on 90 nm process supports Hyper-Threading Technology1. Hyper-

Threading Technology allows a single, physical processor to function as two logical processors.

While some execution resources (such as caches, execution units, and buses) are shared, each

logical processor has its own architecture state with its own set of general-purpose registers,

control registers to provide increased system responsiveness in multitasking environments, and

headroom for next generation multithreaded applications. Intel recommends enabling Hyper-

Threading Technology with Microsoft Windows* XP Professional or Windows* XP Home, and

disabling Hyper-Threading Technology via the BIOS for all previous versions of Windows

operating systems. For more information on Hyper-Threading Technology, see www.intel.com/

info/hyperthreading. Refer to Section 6.1, for Hyper-Threading Technology configuration details.

In addition to supporting all the existing Streaming SIMD Extensions 2 (SSE2), there are 13 new

instructions that further extend the capabilities of Intel processor technology. These new

instructions are called Streaming SIMD Extensions 3 (SSE3).These new instructions enhance the

performance of optimized applications for the digital home such as video, image processing and

media compression technology. 3D graphics and other entertainment applications (such as gaming)

will have the opportunity to take advantage of these new instructions as platforms with the Pentium

4 processor on 90 nm process and SSE3 become available in the market place.

The processor’s Intel NetBurst microarchitecture front side bus (FSB) uses a split-transaction,

deferred reply protocol like the Pentium 4 processor. The Intel NetBurst microarchitecture FSB

uses Source-Synchronous Transfer (SST) of address and data to improve performance by

transferring data four times per bus clock (4X data transfer rate, as in AGP 4X). Along with the 4X

data bus, the address bus can deliver addresses two times per bus clock and is referred to as a

"double-clocked" or 2X address bus. Working together, the 4X data bus and 2X address bus

provide a data bus bandwidth of up to 6.4 GB/s.

Intel will enable support components for the processor including heatsink, heatsink retention

mechanism, and socket. Manufacturability is a high priority; hence, mechanical assembly may be

completed from the top of the baseboard and should not require any special tooling.

The processor includes an address bus powerdown capability that removes power from the address

and data pins when the FSB is not in use. This feature is always enabled on the processor.

Introduction

1.1 Terminology

A ‘#’ symbol after a signal name refers to an active low signal, indicating a signal is in the active

state when driven to a low level. For example, when RESET# is low, a reset has been requested.

Conversely, when NMI is high, a nonmaskable interrupt has occurred. In the case of signals where

the name does not imply an active state but describes part of a binary sequence (such as address or

data), the ‘#’ symbol implies that the signal is inverted. For example, D[3:0] = ‘HLHL’ refers to a

hex ‘A’, and D[3:0]# = ‘LHLH’ also refers to a hex ‘A’ (H= High logic level, L= Low logic level).

“FSB” refers to the interface between the processor and system core logic (i.e., the chipset

components). The FSB is a multiprocessing interface to processors, memory, and I/O.

1.1.1 Processor Packaging Terminology

Commonly used terms are explained here for clarification:

•Intel®Pentium®4 processor on 90 nm process — Processor in the FC-mPGA4 package

with a 1-MB L2 cache.

•Processor — For this document, the term processor is the generic form of the Pentium 4

processor on 90 nm process.

•Keep-out zone — The area on or near the processor that system design cannot use.

•Intel® 865G/865GV/865PE/865P chipset — Chipset that supports DDR memory technology

for the Pentium 4 processor on 90 nm process.

•Intel® 875P chipset — Chipset that supports DDR memory technology for the Pentium 4

processor on 90 nm process

•Processor core — Processor core die with integrated L2 cache.

•FC-mPGA4 package — The Pentium 4 processor on 90 nm process is available in a Flip-

Chip Micro Pin Grid Array 4 package, consisting of a processor core mounted on a pinned

substrate with an integrated heat spreader (IHS). This packaging technology employs a

1.27 mm [0.05 in] pitch for the substrate pins.

•mPGA478B socket — The Pentium 4 processor on 90 nm process mates with the system

board through a surface mount, 478-pin, zero insertion force (ZIF) socket.

•Integrated heat spreader (IHS) —A component of the processor package used to enhance

the thermal performance of the package. Component thermal solutions interface with the

processor at the IHS surface.

•Retention mechanism (RM)—Since the mPGA478B socket does not include any mechanical

features for heatsink attach, a retention mechanism is required. Component thermal solutions

should attach to the processor via a retention mechanism that is independent of the socket.

•Storage conditions — Refers to a non-operational state. The processor may be installed in a

platform, in a tray, or loose. Processors may be sealed in packaging or exposed to free air.

Under these conditions, processor pins should not be connected to any supply voltages, have

any I/Os biased, or receive any clocks. Upon exposure to “free air”(i.e. unsealed packaging or

a device removed from packaging material) the processor must handled in accordance with

moisture sensitivity labeling (MSL) as indicated on the packaging material.

•Functional operation — Refers to normal operating conditions in which all processor

specifications, including DC, AC, FSB, signal quality, mechanical and thermal, are satisfied.
