content: Guys, I just wanted to share with the community that TI has put the new MSP-0 series of microcontrollers on preview.Example:https://www.ti.com/product/MSPM0L1305Disclaimer: Yes, I am a TI employee but also an avid hobbyist. By now means I get any benefit from promoting TI parts here. I just think it is a nice alternative to STM32 and similar. I find interesting especially analog features and packaging.

content: Very interesting, but I'm sure I hardly need mention that the first, last and only question aboutanynew chip release - especially a microcontroller - is: when can I actually buy them?An alternative to STM32 is especially welcome, if only for that reason. They've been totally absent from shelves for about as long as I can remember, and that's really hurting my business.Normally I might be curious about new features; temperature rating is something specifically important in my line of work, so that's the first spec I'd usually look at. But right now,allthe technical specs are secondary to availability.So, with that in mind, when could I get 10 pcs for prototyping, or a few hundred pcs for small volume production? And is there a plan in place to ensure I can get another few hundred early next year? And throughout 2023 and beyond?

I see that you can already request samples. At least my corporate account allows for this. From the product page, go toOrdering & Qualityand then you should be theoretically able to order pre-production samples. TI also sells directly from the web. This simplifies the supply chain. However, I understand your worries.Generally, I can say that availability of a newly released parts is better than of popular parts that are already designed-in in plenty of products worldwide. I think you should be able to get more information on the roadmap and availability on the E2E forum. Questions there go to people "who can talk"

content: I have a TI account, yet I won't bother signing in simply because putting a datasheet behind a sign-in wall is the dumbest thing to do when promoting something. Please send this feedback to the marketing team at TI.

content: Quote from: Warhawk on October 21, 2022, 10:08:20 amYes, I do, and if I can order samples then that's great - but...My comment is a very general one - and yes, I am just venting here, so please don't take it personally - that availability is theonlything that I, or anyone else I work with in the industry, care about right now.I get that semiconductor companies have design teams, and that those teams aren't going to stop designing new products any more than I am. That's understood.It's just frustrating to see new parts being produced, when literally theonlything I want to see semiconductor companies do with their available wafer capacity right now is get existing parts back on the shelves as soon as physically possible, so I can use them and keep my business alive.Under normal circumstances I'd get a little bit excited when I see a new product announcement. Maybe it's something I can use to enable a new design? Maybe it's cheaper than some older chip? Perhaps the new one has <insert cool feature here> that will make my life easier?But right now, the little voice in my head that would ordinarily say "hey, cool" is instead saying "Gaaaahhhh...!" at the thought of any wafer capacity being used on parts I don't need, as opposed to parts that I do.None of the semiconductor companies are really openly acknowledging and dealing with the issue, and that's immensely frustrating.Yes, I know I've gone off topic here, and I'm (slightly) sorry. As I said, it's nothing personal, nor is it something specific to TI. But if you have the ear of anyone who can make a difference here, please pass on the message: new parts are great, but honest, predictable andguaranteedlead times for parts I've already designed in would beincomparablygreater.

content: Quote from: Warhawk on October 21, 2022, 09:08:31 amI'm busy designing out TI, so no thanks.TI's treatment of SMEs during these supplying chain difficulties has been, frankly, atrocious.

I could access and download the datasheet without any problems. Which datasheet are you specifically talking about? This one or another one?

content: The so called datasheet is a 3-4 pages with brief enumerated specs, a block diagram then 10-15 more pages about footprints and packaging. For the rest of the info the webpage says:Quotewhich requires a sign in.

content: I also wonder what the MSPM0L1303 is. The part numbering system doesn't specify. Sure the 1303specifies flash size, but is it really half of the 1304 ? (which is 16kiB).And I really don't understand the datasheet limitation. Is it temporary for being new? I sincerely hope so. It looks pretty jellybean to me, unless the 'stop' mode has features which are undocumented,... The power consumption looks reasonably low but not spectacular.

content: Quote from: voltsandjolts on October 21, 2022, 11:57:05 amvoltsandjolts,I am an engineer in development. Invectives at me do not help. Also, I do not represent TI here on the forum. I put the disclaimer above to avoid misunderstandings. I am only looking forward to playing with these little chips at home during long winter evenings and thought someone else could be also interested.With no irony, and as an engineer, I wish you luck with redesigning your products to have a more diversified BOM. I hope that other suppliers support you better than TI.

content: Quote from: RoGeorge on October 21, 2022, 01:44:21 pmAll right, I see it now. I am logged in. When I click on the request I am greeted with theU.S. Government export approval. I can't tell if this has something to do with corporate practices, with legal requirements or government export control.

content: Quote from: AndyC_772 on October 21, 2022, 11:53:41 amAndy, I completely understand this. I am generally conservative and do not jump on new trends or products still hot from the oven. However, there are different processes used for different parts. It is not a bakery when you one day run opamps and the other day MCUs. Manufacturing of semiconductors is extremely complicated process. Not even mentioning packaging.In my opinion, TI has made some optimistic decisions on extending manufacturing capabilities. See the last paragraph on 300-mm manufacturing capacity.https://news.ti.com/blog/2022/09/29/tis-new-300-millimeter-wafer-fab-in-richardson-texas-begins-initial-productionPS: I have to go pretty much through the same sample process like everyone else. If you don't get samples i won't likely get them either (unless having a more-than-good business reason).

content: Quote from: hans on October 21, 2022, 02:04:20 pmAs far as I understand the datasheet is preliminary because these are pre-production samples. Note the part numbering scheme (devices starting with X or P are typically pre-production samples). IMHO what makes it interesting are the analog features.

content: My best guess for the OPA is TLV369 with additional chop mode (input mux maybe?). I look forward to seeing a full datasheet.

content: Quote from: Warhawk on October 21, 2022, 09:08:31 am2 chopped opamps + 1 normal + a comparator, together with an MCU and for approx $0.64 in 1ku, seems interesting indeed. If the new TI fab can spare customers from future out of stock -> redesign problems, this little M0 could fit a lot of applications.
