82443MX PCIset
1.
INTRODUCTION
The Intel® 82443MX PCIset (440MX) is a single-component mobile chipset that is optimized for Intel® mobile
Celeron™ processors and Pentium® II processors for new Value and Mini notebook platforms.
The 440MX reduces the number of mobile chipset components without requiring any major programming
model changes. It accomplishes this by integrating the 443BX North Bridge chipset (without AGP) and the
PIIX4E South Bridge chipset while adding a two-channel, digital AC’97 link feature. This single-component
mobile chipset is specifically designed to reduce system cost, space and power. The 440MX is packaged in
492 mBGA (the same package as the 443BX).
This document is intended for architects, engineers, product planners and marketing groups who develop
technologies, products or positioning for the notebook PC market segment.
