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 Micro SD connector is supported in RZ/G1E SODIMM SOM, then operating temperature range is -25°C to 85°C.

To meet this humidity specification, conformal coating needs to be done on the boards. By default, iWave boards
doesn’t come with conformal coating. Please contact iWave to support conformal coating.
3.2.2 Heat Sink
For any highly integrated System On Modules, thermal design is very important factor. As IC’s size is decreasing 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.
iWave supports Heat Sink Solution for RZ/G1H Qseven SOM. Please refer the below figure for Heat sink dimension
details. For Heat sink ordering information, refer section 4 ORDERING INFORMATION
