AM335x Operating Temperature Range

Other Parts Discussed in Thread: AM3352

Hi,

Regarding the Temperature Specification of AM3352,
I am little bit confused about the terminologies used in the datasheet.

-40 to 105°(Extended)
-40 to 90°(Industrial)
0 to 90°(commercial)

The datasheet doesn't mention different values for "Operating Temperature Range"
and the "Junction Temperature". And both Operating Temp & Junction Temp values are same.

But the below document mentions "Junction Temperature" is The hottest temperature
of the silicon chip inside the package.
http://www.ti.com/lit/an/spra953b/spra953b.pdf

Should we assume "Junction Temperature" as "Operating temperature" of AM335x?

And is there any details about Absolute Maximum Operating Temperature?

Best Regards
Prad

    Prad,

    Yes, at any given time, the "Junction Temperature" will be the hottest temperature of the silicon chip. However, this temperature can vary anywhere in the "Operating Temperature Range", as specified in the datasheet. For these purposes, we can assume the operating temperature is equivalent to the junction temperature.

    It is important to keep the junction/operating temperature within the recommended operating range (-40 to 105°C for an "Extended" device). The Absolute Maximum Operating Temperature (105°C) should never be exceeded to guarantee functionality and lifetime.

    For more details, please see http://processors.wiki.ti.com/index.php?title=AM335x_Thermal_Considerations.
