F28M36P63C2: MTBF of f28m36

Part Number: DCR010505

Hello,

I am trying to estimate the MTBF of the f28m36 device in the TI C2000 family?? But the datasheet or technical documents does not detail it's FITS rate. Any idea on how i can find this detail? 

Thanks,

Srini

Srinivasan,

Are you looking for the FIT of DCR010505 or F28M36?

Apologies John, I am looking for the FIT of F28M36. 

Thanks,

Srini

Srini,

I'll need to move this.  It is in the wrong forum.

Okay, thank you.

Hello Matthew,

Thank you for your time. The document was helpful in understanding the Useful lifetime of the TI C2000. But I could not find any information on MTBF or FIT? It talks about the dependency in Ambient temperature and electro migration without actually specifying the FIT rate or MTBF of any C2000 device. Am I missing something? Kindly let me know.

Thanks,

Srini

Srinivasan,

For now I think you can use the information for our TMS320F28377D device since it is of the same process technology as the F28M36 you mention.  I will check on why the F28M36 device is not populated in the TI FIT tool.

Thank you, Matthew. Just quickly, the link you provided specifies an MTBF of 4.153 x 10^8. Is this in units of hours or device hours?? Are they assuming assuming 1 FIT is calculated over 10^-9??

The document you shared previously said these devices have a lifetime of 15 years and a PoH of 131,400 hours. Does this relate to the MTBF in any way?? It's really unclear to me. If possible, Would you please shed some light over how this MTBF was calculated. Because the general rule of thumb (1/FIT rate) does not add up.

Thanks,

Srini
