TM4C1294NCPDT: TM4C129 becoming NRND?

Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: MSP432E401Y, TM4C129ENCPDT, MSPWARE, CC2650,

Fellows,

I have recently received news of the MSP432E401Y MCU.

Well, while it is an MSP, one can see that probably 99% of it similar to a TM4C1294 IC.

While I could find no NRND stamped on any of the TM4C pages so far, our company had difficult to purchase the "most popular" 1294 version yesterday. Including lack of availability directly from TI's store. That's a concern for a 3-4 year old product.

TI's site clearly want customers to stay away from TM4C's. They don't actually "exist" when following the natural link order starting at micro controllers (the second square on the image below actually refers to the newer MSPs).

Forum colleagues, I believe we should take a stance of not recommending this IC to new posters, order a couple of launchpads of the new family to get used to it, and start visiting the 32bit MSP forums...

Regards

Bruno

  • I can go a bit father into it now:
    - It appears to be IDENTICAL to TM4C129ENCPDT.
    The MSP offers only one temperature rating, -40 to +105°C, hence it reflects the T3 suffix.
    I checked pin to pin on the layout, and also "as far as the patience allowed me", pin to pin muxing options, all the very same.
    Just wonder if the MSPWare syntax is identical to TivaWare?

  • Hi Bruno,
    TM4C129 will be available for a long time as far as I know. I will suggest you contact your local TI sales office for inquiry.
  • Hi Charles,
    I trust you are right.
    My post is just the result of some stars being aligned. TI not having in stock the same part number that goes in the regular Launchpads was a bit unexpected, and no of the big worldwide vendors have any either. We do have safety stock in our office in Brazil, I just needed a few parts for tests here in Europe - which in the end I solved by ordering the quite similar "crypto" version of the TM4C1294.
    Still, someone considering TM4C129 for a NEW design might be on a safer side if looking at the new MSP432E4 lookalike, can we say that?
    Regards

  • Hi Bruno,

    There are no plans to NRND the TM4C family. TM4C continues to support a very broad and growing customer base. The lack of availability in the TI store has actually been from the popularity of the devices and difficulty to keep stock. I confirm this with our marketing folks.

    MSP432E devices can enable migration to the SimpleLink platform if so desired.
  • Hi Bruno,

    Chiming in a bit too in addition to Charles' answers,

    The only situation that would be true for is if there is interest in migrating from TivaWare to SimpleLink for connectivity rooted applications (particularly wireless). If there is no plan for a customer to leverage SimpleLink and/or there is no plan to move away from TivaWare, then there is no reason to shift from TM4C129 to the MSP432E4 for a new design at this point. The TM4C platform isn't going anywhere.

    TI has never had an obvious link to the TM4Cs as far as I'm able to tell. Notice they do show up on the left under control and automation.

    Analog devices had a similar classification problem last time I checked.

  • Ralph, Charles, that's good to hear! Thanks for the feedback, and I am actually happy to have at least raised the subject and given the opportunity for this assurance!

  • Robert,
    We should not even get started on TI's site structure (and the amazing [lack of] results one gets for searching anything "obvious")!
    But I do believe TM4C's had some place under the spotlight not too long ago... With the site structured as is, ONLY one who knows of it's existence will find that line - IMHO. But, well, that's what the human application engineers are for, uh?
    Cheers

  • Hi Bruno,
    Thanks for bringing up your concern and glad that it is clear to you now that TM4C129/123 are here to stay for a very long time.

    It's always taken me two or three attempts to find the appropriate section. They have some sort of classification scheme that simply does not match my use.

  • Evidence that the TM4C129 isn't going anywhere:

    It is the Debug Probe on all these new Launchpads! :)

  • Most true!
    I see it on my CC2650 launchpad.
    Curious to see if the same TM4C1294NCPDT will be populating the MSP432 LP that I just ordered...
