RPi Compute module high temperature operation

Question

Hello,

Hi, I am working in a prestudy project where we are looking at using the Raspberry Pi Compute Module in a building automation application.

We have difficulties finding info about temperature behavior.

Is there an absolute maximum rating specified for the Broadcom chip or the module as such?

What happens to the functionality of the chip when it reaches high temperatures? Are certain functions disabled? Does it shut down?

Any input appreciated.

I don't think the throttling depends on anything but temperature. The main question to Pal (I have tried copy-pasting into this window to spell that correctly, but some fancy Farnell-stuff blocks that... sorry) is: what is "high temperature". If you want it to run at 100 degrees ambient... 100% certain: you can forget that. If you want to run it at 40 degrees ambient... 100% certain: sure you can! But the throttling may happen earlier than you might expect, and it would be good to keep in mind that the CPU might start to throttle when it hits a heat-limit. If the throttling is bad for your application, you may need cooling measures. If you require maximum performance, you'll further heat up the CPU by having it DO stuff, and the throttling may happen at an inopportune moment....
