General Description

AMD Geode™ LX processors are integrated x86 proces-
sors specifically designed to power embedded devices for
entertainment, education, and business. Serving the needs
of consumers and business professionals alike, it's an
excellent solution for embedded applications, such as thin
clients, interactive set-top boxes, single board computers,
and mobile computing devices.
Available with a core voltage of 1.2V, 1.25V, or 1.4V it offers
extremely low typical power consumption leading to longer
battery life and enabling small form-factor, fanless designs.

AMD Geode™ LX Processors Data Book
While the processor core provides maximum compatibility
with the vast amount of Internet content available, the intel-
ligent integration of several other functions, including
graphics and video datapaths, offers a true system-level
multimedia solution.
For implementation details and suggestions for this device,
see the supporting documentation (i.e., application notes,
schematics, etc.) on the AMD Embedded Developer Sup-
port Web site (http://wwwd.amd.com/dev, NDA required).
