[C6455] Derated life at different speeds/temps

Other Parts Discussed in Thread: TMS320C6455

Hello folks,

I am looking at the TMS320C6455 and I am told that the rated life of the part is at 750 Mhz so if using the part at 1 Ghz the life is derated. Is this correct? I did not see it in the datasheet or errata.

I think what I am looking for is data pertaining to the number of power-on hours at different frequencies/voltages as well as temperatures. Is this available in any fashion? I've seen the spreadsheet to calculate MTBF/FIT under these types of conditions but nothing regarding POH values for this device.

    TimHarron,

    From whom did you hear this about the 750MHz value? They should be the first path to find the source of the answer. It could have come from an out-of-date silicon rev or a specific process node or something else.

    Somewhere there is a specification of what it means for TI to release a part as TMS-qualified. Any deviation from that would be clearly specified in a datasheet. I do not know where that TMS spec is, so I am not helping a lot, sorry.

    Regards,
    RandyP
