1 / 247 page  © 2000 National Semiconductor® Corporation www.national.com April 2000 Geode™ GXLV Processor Series Low Power Integrated x86 Solutions General Description The National Semiconductor® Geode™ GXLV processor series is a new 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 is the perfect solution for information appliance applications such as thin clients, interactive set top boxes, and personal inter- net access devices. The GXLV processor series is divided into three main cat- egories as defined by the core operating voltage. Avail- able with core voltages of 2.2V, 2.5V, and 2.9V, it offers extremely low typical power consumption (1.0W to 2.5W) leading to longer battery life and enabling small form-fac- tor, fanless designs. Each core voltage is offered in fre- quencies that are enabled by specific system clock and multiplier settings. This allows the user to select the device(s) that best fit their power and performance requirements. This flexibility makes the GXLV processor series ideally suited for applications where power con- sumption and performance (speed) are equally important. Typical power consumption is defined as an average, measured running Microsoft’s Windows at 80% Active Idle (Suspend-on-Halt) with a display resolution of 800x600x8 bpp at 75 Hz.
