Suddenly all Cortex-M3 devices became NRND?

Hello guys,

I was surprised this week when found out that most of Cortex-M3 devices became NRND. I checked again today and LM3S9D96 is now ACTIVE again. 

Is there any prediction of discontinuing these devices with the introduction of -M4F devices?

Thanks in advance,

André Araujo

  • Andre,

    I work on the marketing team for the Stellaris products. I can confirm that the LM3S product family is transitioning to NRND by December 1st, 2012.

    Since you are using the LM3S9D96, you should know this is a change in promotional status only. Meaning, there are no plans to discontinue the LM3S devices. We will continue to manufacture, support, and document LM3S devices for years to come. All existing business agreements will also be honored.

    This change is really intended as an incentive for customers to consistently look towards the new LM4F family for new product developments.  

    LM4F microcontrollers with an integrated Ethernet MAC + PHY are coming soon from Texas Instruments. For roadmap info, reach out to your local TI sales contact and we can cover the material under NDA. Until then, I recommend that you continue to use the LM3S9D96 or take a look at our Concerto family of Cortex-M products.

    Thank you for your post.

    Hello Miguel,

    Thanks for the quick answer!

    Best regards,

    For those wondering (like me) I am Guessing that NRND stands for "Not Really Nice Devices" -- or something similar.

    Since it wasn't explained...

    Did I mention that I hate Acronyms?

  • In reply to Dave Robinson:

    Sorry, Dave - it stands for Not Recommended for New Designs.

    Fair point. Acronyms can be annoying. :-)

    NRND = Not Recommended for New Designs.

    How about "material under NDA"?

    So you're deprecating Cortex-M3 in favour of Cortex-M4?

    That sounds like one massively Huge Mistake  to me!!

    So we shall have to go elsewhere for Cortex-M3 and Cortex-M0...

    Well, obviously, that's just a Non-Defined Abbreviation!!

  • In reply to Andy Neil:

    I hope I don't have to sign a Non Disclosure Agreement (NDA) to get an answer to this question...

    Suppose I wanted to design something with an Ethernet Controller -- and seeing that we would be discouraged from using TI LM3S with Ethernet (say LM3S6965 )-- does that mean I should chose the LM4F????666??? or what processor???? ...exactly...

    Just askin'

    Not upset like Andy -- but perhaps a bit bemused at this apparent oversight...

  • In reply to Dave Robinson:

    Dave,

    I understand your point, and despite the promotional status you can still use the LM3S ethernet devices for your applications. They are still being manufactured and supported, so the change should have little to no impact on the work our customers do with the parts.

    We do have replacement Ethernet devices lined up, and I can assure you were are working hard to bring those to you guys as fast as possible.

    Regards, ~Miguel
