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.

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.

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)

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.
