Not sure it was mentioned here, but just an FYI. It's done in the morning in the North American territory, so should be reachable by the European audience late afternoon.

Google Hangout ''Getting started with STM32L4, latest ST Ultra-low- Power Microcontroller'' on Thursday, October 1st at 9 a.m. PDT.

Not sure if it's going to be much more than a slide deck, but they normally do a Q&A so if you have pressing questions this would be a good opportunity to get mind share with those in the sales and marketing, and the FAE's The day long seminar series kicks off 20-Oct-2015 in Chicago #lets-break-the-internets

Sounds interesting. Unfortunately a bit late here in Australia (1:30am). If someone could pin them down about details of an LQFP48 package version  it would be appreciated.

That is about 5:00 CET (central european time) - so says the reminder mail from ST.

Somewhat evasive of a roadmap/timeline, inferred something would appear in 2016

The LQFP48 question got a couple of +1's from others, the part's crying out for this kind of form-factor, not everyone needs lots of pins. Instead of non-committal answers, try and address the technical reasons why it's not already available, is the die too big, I can't believe the package is a problem like it would be for more exotic/specialized BGA ones. LQFP's are things people want to use in low cost, low complexity board designs, they are easy to manufacture in lots of markets.

The thing that got the most hits was the question about the LL (Low Level) library, vs why can't we get the SPL. I think there's significant frustration with the abandonment of the SPL. Got a couple of Eclipse and Visual Studio questions, I've used the Atmel Studio guys, and it's a painfully slow running platform. Will it run ucLinux, I'd guess you'd ask

I just scratch my head about why you'd want to do this on a slow platform, what does bringing Linux to the party solve? The F7 at least has good/large external memory option, memory management and caches. Can someone given me a cogent use case here?

I think there's significant frustration with the abandonment of the SPL. https://youtu.be/myx_UKe0SSU?t=4255 The whole thing was pretty boring, the bulk of it was basic glossy-paper-stuff reading. I'd love to see better information-to-time ratio, should this be repeated. I hope the live seminars supply more substantial information, most of the attendees should be able to read. JW

Thanks for your efforts Clive and JW.

I'm not sure why ST is so secretive about this issue (LQFP48). I reckon an LQFP48 part would do more to introduce this chip to new people and new products  than any number of Discovery boards.My concern is that there are no technical reasons why it could not be done now - and that it is just a marketing decision. Until I see some written confirmation I will keep pestering... I mean lobbying.

While I think the wafer scale parts might have large volumes, the number of customers is very low, whereas I think the appeal of the small LQFP is much broader. There are lots of things that are compute heavy that don't need a lot of pins.

I'd be interested in the percentage spread for the different F4 foot prints currently.

Hello,

Thanks for your feedbacks. Regarding the packages. Most of packages available on STM32L4 are already LQFP (LQFP64, LQFP100 and LQFP144).The reason to not have LQFP48 available now is not maketing but technical. Indeed it is not possible to address with the same die a very large spread of pinout for LQFP. We already adress a large range from 64 to 144 pins. It will come with future derivatives. Stay tuned. :)Hope it clarifies.Thanks,Bertrand
