3.4.2 Supply Current (Windows XP SP3)
The testing performed to capture the supply current data used tested modules
mounted on a Kontron evaluation board with a mouse and keyboard connected.
The power consumption tests were executed in Windows XP (with SP3) using a
tool to stress the CPU at 100 % load. The power measurement values were
captured after 15 minutes of full load or a stable CPU core temperature of
90°C. 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 a 1024-MB DDR SDRAM. The modules were tested using the maximum
CPU frequency. For more detailed information, refer to the “Power
Consumption” diagrams on the EMD Customer section of the Kontron website.

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 values measured in the table above. Take this into
consideration if you are at the limit of the thermal specification, in
which case you should consider improving your thermal solution.
