Geode™ GX1 Processor Series Low Power Integrated x86 Solution April 2000 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 entertainment, education, and business. Serving the needs of consumers and business professionals alike, it’s the perfect www.DataSheet4U.com 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. Available 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.
