TMS320C6678 Part Numbers

Could someone please explain what the differences are between these part numbers?  The 6678 data sheet does not say what features are enabled for which part numbers. 

  • TMS320C6678CYP – Standard 1 GHz
  • TMS320C6678CYP25 – Standard 1.25 GHz
  • TMS320C6678ACYP – ??
  • TMS320C6678XCYP – 1GHz with security accelerator?
  • TMS320C6678CYPA – Extended temperature range

 

  • The datasheet contains a figure that explains the various part numbers.  Please refer to Figure 2-17 on page 65.

    Thanks!  I looked at that section, but failed to goto the next page.  /sigh

    Hi,

    Regarding to the standard speed, if I have a 6678 which standard is 1 GHz can I use it at 1.25 GHz?

    Is this the reason why the platform that comes with xdc has a clock speed of 1 GHz instead of 1.25 GHz?

    And why do we have two standard clock speeds? They come from different parts of the wafer or the 1 GHz are older than 1.25 GHz and as the fabrication process improved we got faster DSPs?

    Regards

    The Device Speed Range parameter indicates the maximum clock speed of that particular device.  Therefore, to answer your question, no, it would not be appropriate to purchase a device spec'ed at 1GHz (tested, etc) and run at 1.25GHz.

    Providing Device Speed options offers customers with options and the opportunity to perhaps save a little or spend more money for the performance.

    Brandon,

    Thanks for your answers, now I understood it.

    Brandon,

    I was wondering if it's possible to know exactly tha part number of the DSP chip that comes with the EVM without taking off the cooler and looking at it.
