1 Introduction
Using Intel’s advanced 0.18 micron process technology, the Intel mobile Pentium III processor
offers high performance and lower power consumption. Key Performance advancements include
the addition of new Internet Streaming SIMD instructions, an advanced transfer cache
architecture, and a processor system bus speed of 100 MHz. These features are offered in BGA2
and micro-PGA2 packages that are up to 20% smaller than those offered for the Intel mobile
Pentium II processor. All of these technologies make outstanding performance possible for
mobile PCs in a variety of shapes and sizes.
Intel mobile Pentium III processor featuring Intel SpeedStep technology is the next dramatic
step towards achieving near desktop performance. This exciting new processor has two
performance modes and allows real-time dynamic switching of the voltage and frequency between
the modes. This occurs by switching the bus ratios, core operating voltage, and core processor
speeds without resetting the system.
The integrated L2 cache is designed to help improve performance, and it complements the system
bus by providing critical data faster and reducing total system power consumption. The mobile
Pentium III processor’s 64-bit wide Gunning Transceiver Logic (GTL+) system bus provides a
glue-less, point-to-point interface for an I/O bridge/memory controller, and is compatible with the
440BX AGPset, 440ZX-M AGPset, and the 440MX Chipset.
Figure 1 shows the various parts of a
mobile Pentium III processor/440BX or 440ZX-M AGPset -based system and how the mobile
Pentium III processor connects to them.
Figure 2 shows an alternative mobile Pentium III
processor/440MX Chipset - based system.
This document covers the electrical, mechanical, and thermal specifications for the mobile
Pentium III processor featuring Intel SpeedStep technology at the following frequencies: 850
MHz, 800 MHz, 750 MHz and 700 MHz in BGA2 and micro-PGA2 packages, and 600 MHz at
low voltage in BGA2 package.
