TM4C1231H6PGE: Allowable Junction Temperature

Felix Arul Rajesh Francis
Intellectual 470 points
Part Number: TM4C1231H6PGE

Hi

We are using Tiva™ TM4C1231H6PGE Microcontroller  for our application.

In the datasheet, we are seeing a huge difference between the Absolute Max Junction temperature (150degC) and Operating characteristics Junction Temperature (94degC).

Why is this huge gap? What would be the recommended operating condition? only 94degC or can we exceed from this.

Our device is a power hungry, already the measured temperature on this micro controller comes around 105degC.

This could be a cumulative effect of power dissipation at the component and the internal system temperature.

Kindly clarify  how max we can go beyond 94degC.

Regards,

Felix.

    The part is not guaranteed to operate properly if you exceed the maximum operating junction temperature. Operating above the absolute maximum rating may cause permanent damage to the device. Operating at a temperature above the maximum operating temperature may cause (among other things) higher operating currents, lower operating speed, out of specification input and output levels, excessive flash programming times and premature flash data retention loss.
