Geode™ GX1 Processor Series

Low Power Integrated x86 Solution

General Description

The National Semiconductor^®Geode™ GX1 processor

series is a line of integrated processors specifically

designed to power information appliances for entertain-

ment, education, and business. Serving the needs of con-

sumers and business professionals alike, it’s the perfect

solution for IA (information appliance) applications such as

thin clients, interactive set-top boxes, and personal internet

access devices.

The Geode GX1 processor series is divided into three main

categories as defined by the core operating voltage. Avail-

able with core voltages of 2.0V, 1.8V, and 1.6V, it offers

extremely low typical power consumption (1.2W, 1.0W, and

0.8W, respectively) leading to longer battery life and

enabling small form-factor, fanless designs. Typical power

consumption is defined as an average, measured running

Microsoft Windows at 80% Active Idle (Suspend-on-Halt)

with a display resolution of 800x600x8 bpp at 75 Hz.
