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.
