Thermal Considerations
AT91FR40162S Preliminary
The average chip-junction temperature T
Where:
From the first equation, the user can derive the estimated lifetime of the chip and thereby decide
if a cooling device is necessary or not. If a cooling device is to be fitted on the chip, the second
equation should be used to compute the resulting average chip-junction temperature T
