TMS320F28033-Q1: TMS320F2803xT (105°C) vs TMS320F2803xQ / any difference ? Urgent

Part Number: TMS320F28033-Q1

Hi all

Our customer has so far been using e.g. the TMS320F28033PAGQ and the TMS320F28034PAGQR in their projects.

Due to the currently constrained supply situation they have this urgent question, please review and comment.

To summarize: Is there any difference in specs (apart from the temperature range) between the Q and non-Q devices ?

Best regards

Ueli

----------------------------------

On my side, I try to qualify the TMS320F2803xT (105°C) in replacement of TMS320F2803xQ (125°C) on some projects

But to be sure, I need to be sure about the differences between the 2 references. Could you please outline if there is technically a difference ?

Are these exactly the same components, done on the same assembly lines but with more or less tests and measures ?

    Ue,

    Q and non-Q devices use the same silicon at its core. 

    They often use the same packages.

    I cannot comment on the mold compounds used by each temperature grade.

    The test procedures are quite different though. There is a significant amount more tests applied to Q devices.

    Thank you for the quick reply. 

    The customer just wants a confirmation that there is no difference in electrical specs for the -T vs. the -Q variant.

    Can you confirm this ?

    Best regards

    Thank you for you reactivity!

    We still have the following questions please:

    • What the differences are in terms of temperature tests between these 2 classes?
    • Are the components of the T class the same as those of the Q class but they only have not undergone all the tests of the Q class?
    • Or is it known all along that the T class components are different and less efficient, and that is why they were classified as T? 

     

    Many thanks!

    The T and Q variants are electrically identical.

    I do not believe I can disclose the test procedures for these devices publicly. But as I said before the Q variant undergoes more testing.
