SM320F28335-HT: Clarify the pin option of some SM320F28335GBS units

Part Number: SM320F28335-HT

Hi,

We are purchasing the P/N SM320F28335GBS from an stockist and we have a doubt about the pin option.

In the page 179 of the SM320F28335-HT datasheet, it says that 2 options are available at production respect to the pins:

  • Gold-plated pins.
  • Solder-dipped pins.

We need to clarify if the units that the stockist has are the gold-plated option. He sent us a picture of the pins.


Could anyone confirm that the units correspond to the gold-plated pins option? Is it possible to obtain a picture of the solder-dipped pins option for visual comparison?

Thanks.

  • Juan,

    I think the note in the DS about the pin plate/dip options is carrying over from the general package options that available the package itself.  I do not see any options in the build information nor is there separate order-able for solder dip on the product page linked above for this specific device.

    Based on the image(thanks for attaching), these are gold plate option.  If there were a solder-dipped option I would expect to see a distinct order-able PN, which is not there.

  • Hi Matthew,

    OK, thank you for the information.

    I have a doubt. In another post I have been talking about the RoHS compliance of the P/N SM320F28335GBS. The final resolution was that the gold-plated pins option is RoHS.

    You mentioned that the solder-dipped pins option does not exist, so why does the SM320F28335GBS web page say it is non RoHS compliant? Could that page be updated with the corrrect information about RoHS?

    Regards,

    Juan Manuel.

  • Juan-Manuel,
    Thanks for pointing this out, my colleague has looped me into an internal email regarding this.  Will get back with you once we know more.

  • Hi Matthew,

    Any news on the last questions?

  • Juan Manuel,

    Based on the internal device build sheet, this device is indeed, RoHS compliant.  We are working to get the material data uploaded to TI so this can be seen.

    Here is my thoughts on why TI.com is showing this as a "no"

    1)As you pointed out, the package information has a note that informs that there is an option to have pins solder dipped 

    2)If this were selected, I believe that it would mean that the device is no longer RoHS compliant

    3)That note, however, is a general one meaning the package is capable of this process; but it would be up to the device owner(C2000 in this case) to provide that as an orderable option for the customer

    4)In this case, we don't. :)  There is no TI.com option, or option set up in our ordering system to support a solder dipped version of this device.

    5)Going back to the RoHS status on TI.com, I think that in the absence of the material content list that should be associated with this device, the system is just defaulting to "No" for RoHS since it doesn't see support one way or the other.  My hope is that when we get the material content updated, it will change that internal flag to "yes"

    For now you can use this thread as proof from TI that the material is RoHS compliant.

    Best,

    Matthew
