Microcontroller operating in 70 celcius

[jining]

Hello,

In my project, my microcontroller may have to operating in +70 celcius C.Will this temperature influence the board behave? Any electronic elements on the board could be have a problem with the high tempreature?

please any idea will be valuable for me!

The Microcontroller operating temperature range is -40 celcius c to +85 celcius C


please any idea will be valuable for me!

That is why they publish such information in data sheets. Try
reading the data sheet for the components you will be using and de
rate for temperature where necessary.

Yes, the temperature will influence how the board behaves vs. room
temperature.

Yes, electronic components can have problems at high temperatures.

If you're designing the board, pay attention to the temperature range of
each part, and design the circuits to the data sheets' worst-case
specifications. Also pay attention to the power consumed by each part,
and calculate the heat rise so that you know the parts are operating
within spec. Then test.

If you're buying a board, try to get a candidate board that's rated for
the temperature, and before you're 100% committed to using it, try to
test it at temperature.

As someone said you have to check the spec sheets. Typical operating
range is to 85C. But I don't know about uC's. You have to look at
the derating of any power components on the board. At higher ambient
temperature they get too hot if asked to disipate too much power.

What "microcontroller"?

All these things have specifications. Find
the datasheet and/or specifications for
whatever microcontroller you have.

Anything else is just guessing.

it's hot, but not too hot for most things.

start downloading datasheets.

Look for automotive grade parts. They regularly have to deal with ambient
temperatures above that.
