Hi Keng,

The only thermal related data I am able to find is in below docs:

www.ti.com/.../tms320dm643.pdf - section 7.1 Thermal Data

www.ti.com/.../spraal9.pdf

I will check with factory team for CTE value and come back to you if I am able to find something.

Regards,
Pavel

Hi KPK

I do not think we have a value to offer, on previous requests, our package team's guidance has been that there is no simple answer. Each ingredient in the package has a unique value. It is not possible to provide a single value for the processor package.
