Introduction
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
