Supply Current (Windows XP SP2)
The tested boards were mounted on a Kontron Evaluation Board (Article number: 18010-0000-00-0), a
mouse and a keyboard were connected. The Power-consumption tests were executed during Windows XP
SP2 by using a tool to stress the CPU (100 % load). The power measurements values were acquired after
15 min full load and a stable CPU die temperature. To ensure a stable die temperature a corresponding
heatsink was used to hold the temperature under the critical trip point.
All boards were equipped with 512MB DDR SDRAM. The Modules were tested using maximum CPU
frequency.

Note:
It is difficult to test for all possible applications on the market. There may be an application that draws more
power from the CPU than the measured values in the table above. This should be taken into consideration if
you are on the board of the thermal specification. If this is the case improvements to your thermal solution
are recommended.

CMOS battery power consumption was measured with an ETX®-CN8 module on a standard Kontron ETX®
evaluation board. The system was turned off and the battery was removed from the evaluation board.
The 2.5 V or 3.0 V of power was supplied from a DC power supply. Do not use these values to calculate the
CMOS battery lifetime.
