Intel
®
440MX Chipset
For Applied Computing
The Intel
®
440MX chipset represents the latest
in chipset integration. By providing a cost
effective, low power single-component chipset
specifically designed to reduce system cost,
space and power, this product is ideal for low-
power, low cost applied computing platform
solutions. The 440MX chipset offers designers
an extremely cost effective way to enable Intel
quality, reliability, and initiatives across all their
low power market segments.
The 440MX chipset supports low power Intel
®
Celeron
TM
processor and Intel
®
Pentium
®
III
processor designs. The 440MX is offered in the
small form-factor, 492 Ball Grid Array (BGA)
package with a typical power dissipation of
2.1W making it an effective solution for fanless
applications.
The 440MX chipset provides advanced
features like support for USB, ACPI power
management and AC-97 link interface, which
enable soft technologies. The chipset is a single-
component that integrates the North Bridge and
the South Bridge and an additional AC-97
digital link (2 channels) into one chip. It
replaces the ISA interface with an 8-bit X-bus
that supports KBC, SIO, and Flash memory.
Figure 1 illustrates a block diagram of the
440MX platform.
