LPC2378 temperature testing

I am looking at using the LPC2300 series at boarder lining temperature range 90+ degC for a customer. I know the chip is rated to industrial temperature range but it there any possibility it can go higher? Is there any production data which can tell me its test range?

I have tested a few trails in a oven to see how far I can push it and I find that some work well over a 105degC and others fail around 95degC.

Can you help me understand why that is and what happens when it fails?

It is really important for me to know as I worry it is not the MCU that fails but a external part.

 

What do you think?

Your answer is really appreciated as this is dogging me. I would love to use a different chip but currently it is not an option.

 

Kind Regards,

Soren
