¹ iWave guarantees the component selection for the given operating temperature. The operating temperature at the
system level will be affected by the various system components like carrier board and its components, system enclosure,
air circulation in the system, system power supply etc. Based on the system design, specific heat dissipating approach
might be required from system to system. It is recommended to do the necessary system level thermal simulation and
find necessary thermal solution in the system before using this board in the end application.
² If Expansion connectors are supported in RZ/G1M/G1N Qseven SOM, operating temperature range is -35°C to 85°C.
If Micro SD connector is supported in RZ/G1M/G1N Qseven SOM, operating temperature range is -25°C to 85°C.

3.2.2
Heat Spreader
For any highly integrated System On Modules, thermal design is very important factor. As IC’s size is decre
asing and
performance of module is increasing by rising processor frequencies, it generates high amount of heat which should
be dissipated for the system to work as expected without fault.
To dissipate the heat, appropriate thermal management technique like Heat spreader, Heat sink must be used. Always
remember that, if you use more effective thermal solution, you will get more performance out of the CPU.
Heat spreader acts as thermal coupling device between Module and external thermal solution. Heat spreader also
provides thermal coupling to CPU via gap filler for better heat exchange. Heat spreader is not a complete thermal
solution by itself. Heat spreader has to be used with application specific thermal solutions like heat sinks, Chassis, fans,
Heat pipes etc.
iWave supports Heat Spreader Solution for RZ/G1M/G1N Qseven SOM. Please refer the below figure for Heat spreader
dimension details. For Heat spreader ordering information, refer section 4
