It's highly unlikely you will get any meaningful guarantee. They are not often available and when they are the ones I've seen contain enough caveats to essentially render them pointless.

Robert

Hello Rajesh,

What is the timeline of guarantee that you are looking at?

Hello Robert,

Not to forget the post from David maples

e2e.ti.com/.../434175

I am looking the part being available for at least 10 years.

Your concern can be mitigated by purchasing a sufficient quantity in advance - to "meet" your required quantities. Most always - if you pay attention - alerts are issued prior to a device going, "EOL." That notification (classically) signals your "life-time" buy.

As you are unable (or unwilling) to provide the vendor with a firm, unbreakable, purchase schedule how can you expect the vendor to make such a commitment to you?

As poster Robert indicated - it is unusual for most vendors to make such a commitment.   In addition - in so long a period - multiple improvements are likely which you and your user-clients will be unable to exploit - locked as you are - to one (older, less capable) device...

Hello cb1,

What I am trying to find out is that this vendor has enough incentive to keep making this part for at least 10 years before they send out a EOL. I don't want to design this part in and then get a EOL in less that two years or so of me starting to use it. That does not make good business sense. I don't want to buy another 8 years worth of inventory.

I agree with your premise - but it proves, "outside the interests" of most all such vendors! You must realize that as the device ages - and demand fades - maintaining all of the unique device records, materials, masks, etc. is costly, time & space consuming. (I past worked at a similar, giant semi-firm - know this to be true!)

You speak of vendor incentive - yet the rarity and resistance of ANY vendor - to such a long-term (and blind) commitment - is well known & quite public.   In my personal semi biz experience - it is ONLY your financial guarantee to purchase minimum device volumes - which (may) enjoy ANY chance.   (and even then - odds are against you!)

This demand may be coming from your client - or (even) from a regulatory requirement. (a whole new test sequence may be required should you change parts) And in such case "you" are trapped.

I'd suggest that (only) if your volumes are compelling in their size/volume does such a quest have (even) the slightest chance. You'll gain great insight by enlisting the aid of your local Sales Agent - who I will (almost 100% guarantee) will be unwilling to commit in writing (with penalties) for such a TEN YEAR promise of availability.

Again - this is not my being "mean" - it is (instead) a better recognition of the "semi" business reality...

Hello Rajesh

Are you looking for a guarantee on paper from Texas Instruments? Or for that matter any other vendor?

Well not necessarily a written guarantee but some sort of a reasoning why this part won't go EOL in just a few years.

Hello Rajesh

As you can see in the E2E post that I put in my earlier response, this product has been in production for 2 years now and the part is still ramping in sales. The TM4C123x which has been in production for slightly more 3 years has still growing market base.

Indeed cb1,

You can get some idea of ongoing supply by looking to see if it is a standard stock part at the big online distributors. If the part is largely going to a few large buyers (automotive parts come to mind) then they are vulnerable to those buyers stopping their purchase and conversely to those buyers buying all the available stock.

Parts have gone out of production because customer demand slowed, a fab got shut down, a supply chain issue, a fab got overloaded, manufacturers merged, a line of business has gone out of fashion and apparently loss of masks for production. Seldom is the pending shutdown widely known before the EOL announcement.

Robert

BTW, the chance of your board having at least one part go obsolete over 10 years approaches unity.

Robert

Robert,

Ooh - everyone missed that one!   (at least one part going obsolete.)

Poster - while Amit is encouraging - he cannot (and surely will not) make any binding promise.   Nor will most all (other) vendors

Several hundred years ago a, "Fountain of Youth" was discovered - and those (unwritten) claims (too) wore away prior to their "expiration date!"

Hello Robert

Excellent point.
