C6674 -- Overheating in application -- Lower power option

Other Parts Discussed in Thread: TMS320C6674

Hi Team,

I am working with a customer that is having a heat issue with their TMS320C6674ACYPA device in their system.  They need a lower power device and want to explore their options.

 

Is their only option stepping down in core count in order to reduce power consumption?  I don't think a clock frequency reduction is going to be feasible in their application.

    Rob,

    Can you clarify exactly what's happening in regards to 'overheating', is it a matter of current draw, device temp, etc.

    A good amount of the power will be leakage current, which can be controlled to a degree with appropriate thermal solution.  In ineffective thermal solution could result in higher than anticipated temps, and then higher current draws.

    Have they filled out the power spreadsheet for worst case power consumption analysis,  And implemented a thermal solution based on this?

    Best Regards,

    Chad

    Hey Chad,

    Thanks for the quick reply.  I have looked through the wiki for the power consumption spreadsheet and only found the Keystone II family.  Is there a separate spreadsheet for Keystone devices?

    Rob,

    The power spreadsheets are device specific, and are under the model section of each devices external website -> TMS320C6674.

    Best Regards,
    Chad
