TM4C1294KCPDT: TM4C1294 life cycle

Part Number: TM4C1294KCPDT

I'm trying to replace an obsolete LM3S9D92. Lae last thing our client wants is to visit the obsolete part redesign again any time soon. Where can I find the life cycle information on the TM4C1294?

    Hello Loren

    TM4C129x device has been in production for just over 2 years. We do not think there is an EOL planned on this device for the next few years.

    Thanks. I was hoping for a date far in the future (like 2025) but I suspect since it is only 2 years old it will be around awhile.

    Regards,
    Loren

    You may search for a device w/broad, general features - none too "rare or specific." In that way - migration - painful as it may be - is achieved w/minimal, "pain & suffering."

    You & your client could solve your, "supply forever" objective by making regular purchases - insuring that you're always adequately stocked.    As often happens - you/your client "resist" - and seek to shift the entire "build/test/stock" burden to the vendor.

    Minus your contractual commitment - can you (reasonably) expect the vendor to produce parts for you - far into the future?    Reality is not always pleasant - yet should be accepted...

    Unfortunately we we burned with the LM3SD92 going EOL suddenly right after we started full production. We don't want to get burned again and our client wants a lifecycle commitment not just good intentions.

    You/your client were, "far from alone" in the notorious LM3S fiasco. (you may read my writings here - strongly protesting the "less than sterling" manner in which the "beheading of LM3S" was handled.)

    BTW - do you believe that you've received ANYWHERE NEAR a "lifecycle commitment" right here? It is almost iron-clad that NO vendor will make such a one-sided commitment! (as my earlier post detailed...) Reality must be accepted!

    Hello Loren,

    Even though the LM3S decision is very unfortunate for a lot of customers, I have to agree with cb1. No vendor can given a commitment.
