Introduction

1Introduction

The Intel®Pentium®M processor based on 90 nm process technology featuring 2-MB L2 cache

and 400-MHz front side bus (FSB) is the next generation high- performance, low-power mobile

processor based on the Intel®Pentium®processor architecture.

Throughout this document, Intel Pentium M processor based on 90 nm technology featuring 2-MB

L2 cache and 400 MHz FSB will be referred to as Pentium M processor, or simply the processor,

including low voltage and ultra low voltage processors.

This document contains specifications for the Pentium M processors 765/ 755/ 745/ 735/ 725/ 715

Standard Voltage, 778/758/738 Low Voltage and 773/753/733J/733/723 Ultra Low Voltage.

Intel processor numbers are not a measure of performance. Processor numbers differentiate

features within each processor family, not across different processor families. See www.intel.com/

products/processor_number for details.

The following list provides some of the key features on this processor:

•Supports Intel®Architecture with Dynamic Execution

•On-die, primary 32-KB instruction cache and 32-KB write-back data cache

•On-die, 2 MB second level cache with Advanced Transfer Cache Architecture

•Way set associativity and ECC (Error Correcting Code) support

•Data Prefetch Logic

•Streaming SIMD extensions 2 (SSE2)

•400 MHz, source-synchronous FSB

•Advanced power management features including Enhanced Intel SpeedStep®technology

•Micro-FCPGA and Micro-FCBGA packaging technologies

•Manufactured on Intel’s advanced 90 nanometer process technology with copper interconnect.

•Support for MMX™ technology and Internet Streaming SIMD instructions

•The processor’s data prefetch logic fetches data to the L2 cache before L1 cache requests

occurs, resulting in reduced bus cycle penalties and improved performance

•Micro-FCPGA and Micro-FCBGA packaging technologies, including lead free SLI (second

level interconnect) technology for the Micro-FCBGA package (for Pentium M processors 755,

745, 778, 758, 738, 773, 753, 733J/733, 723)

•Execute Disable Bit support for enhanced security (available on processors with CPU

Signature = 06D8h and recommended for implementation on Intel®915 Express chipset

family-based platforms only)

The Pentium M processor will be manufactured on Intel’s advanced 90 nm process technology

with copper interconnect. The processor maintains support for MMX technology and Internet

Streaming SIMD instructions and full compatibility with IA-32 software. The on-die, 32-KB

Level 1 instruction and data caches along with the 2-MB L2 cache with advanced transfer cache

Introduction

architecture enable significant performance improvement over existing mobile processors. The

processor’s data prefetch logic fetches data to the L2 cache before L1 cache requests occurs,

resulting in reduced bus cycle penalties and improved performance.

The streaming SIMD extensions 2 (SSE2) enable break-through levels of performance in

multimedia applications including 3-D graphics, video decoding/encoding, and speech recognition.

The new packed double-precision floating-point instructions enhance performance for applications

that require greater range and precision, including scientific and engineering applications and

advanced 3-D geometry techniques, such as ray tracing.

The Pentium M processor’s 400-MHz FSB utilizes a split-transaction, deferred reply protocol. The

400-MHz 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 3.2 GB/second. The FSB uses Advanced

Gunning Transceiver Logic (AGTL+) signaling technology, a variant of GTL+ signaling

technology with low power enhancements.

The processor features Enhanced Intel SpeedStep technology, which enables real-time dynamic

switching between multiple voltage and frequency points. This results in optimal performance

without compromising low power. The processor features the Auto Halt, Stop Grant, Deep Sleep,

and Deeper Sleep low power states.

The Pentium M processor utilizes socketable Micro Flip-Chip Pin Grid Array (Micro-FCPGA) and

surface mount Micro Flip-Chip Ball Grid Array (Micro-FCBGA) package technology. The Micro-

FCPGA package plugs into a 479-hole, surface-mount, zero insertion force (ZIF) socket, which is

referred to as the mPGA479M socket.

Pentium M processors with CPU Signature = 06D8h will also include the Execute Disable Bit

capability. This feature combined with a support operating system allows memory to be marked as

executable or non executable. If code attempts to run in non-executable memory the processor

raises an error to the operating system. This feature can prevent some classes of viruses or worms

that exploit buffer overrun vulnerabilities and can thus help improve the overall security of the

system. See the Intel®Architecture Software Developer's Manual for more detailed information.

Intel will validate this feature only on Intel 915 Express chipset family based platforms and

recommends customers implement BIOS changes related to this feature, only on Intel 915 Express

chipset family based platforms.

Note: The term AGTL+ is used to refer to Assisted GTL+ signalling technology on some Intel processors.

Introduction

1.1 Terminology

1.2 References

Material and concepts available in the following documents may be beneficial when reading this

document. Please note that “platform design guides,” when used throughout this document, refers

to the platform design guides listed below:

Term Definition

# 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).

XXXX means that the specification or value is yet to be determined.

Front Side Bus

(FSB) Refers to the interface between the processor and system core logic (also known as

the chipset components).
