TMS320C6747: Authenticity HST 6081 test

Hello Thuan Ho,

Thank you for the query.

Can you please provide some background on the authenticity HST 6081 test using Dynasolve 75 you have performed.

Regards,

Hi Sreenivasa,

The HST 6081 process is one of the standard test to detect counterfeit chip.  Usually this test we use Dynasolve 750 to scrub on the top marking to make sure the top making is not removed (maybe lightly remove) or paint come out from top marking.  Usually it does remove the top marking lightly, but in this case as you can see it is removed completely.  I just would like to know if this specific part the blacktop is resistant or not to the Dynasolve 750 solvent.  Also the overspill around the edges are fine?  Your help would be appreciated.

Hello Thuan Ho,

Thank you for the explanation.

Let me check internally and update you. Please expect some delay as i reach out to the expert.

Hello Thuan Ho,

Please refer below inputs and let me know your thoughts.

The devices should be legitimate if purchased from a TI authorized distributor and we do not prove any support for devices that were not purchased from a TI authorized distributor.

Hello Sreenivasa,

That is exactly what I want to find out if the component is legitimate before I purchase.  The die marking and top markings look authentic, but the top epoxy is removed by applying Dynasolve 750.  Is it ok?.  This is my only question to make decision to purchase.  I shouldn't ask for your advice if I know 100% sure it is TI made.  I think the distributor is TI authorized, but double check would be better, don't you think?

Hello Thuan Ho,

Thank you for the note. 

I internally checked with the  packing team and they say we don’t run that test and thus can not comment on how marking may react to such a test.
