What would be the cost of getting my hands on one of those? I would be interested on a pre-production chip in its final form.
Kind regards, Samuel Lourenço
Under $100 if we charged for it. Maybe you'd get it for free. All of you here have made contributions to the chip which are worth more than $100.
That is very nice of you. However, I would be glad to pay for it, since in my case I did not made any contributions. Microelectronics is not my area at all, so I can't say or suggest anything. As for the others who contributed, that would be a nice gesture.
I think I'll wait for a production unit. They will be available perhaps may or June 2019, right?
oh man. I am waiting for this a long time. And I think I am not alone!
I really need this one so badly for a project. For now, I am squeezing every clock and every bit out of P1. But it is just not big/fast enough.
Is there any chance I can get 1 or 2 from the "first" batch? any price.
I need to start production this year and getting more and more problems with defending my choice of controller to my boss. fingers crossed!

If your boss wants something 'to start production this year', you probably need an interim 'P1.5 solution' - ie add some sort of assistance to that P1, which sounds like is close ?
There are many choices, depending on where 'it is just not big/fast enough', you could add another small MCU, or maybe a FPGA helper ?
Then, that can migrate to P2.

No way you can even think this, even if you could get 10 or 100 chips "this year", they still haven't been proven, that's why only a handful are being packaged. If those initial samples don't check out then it could be another year probably to find out what went wrong, to fix it, to simulate it etc, to do another sample run etc before we see the B version.
However, as for squeezing every clock and every bit out of the P1 I doubt that is the case since I get a lot out of the P1 with Ethernet and FAT32 and communications etc and I still have cogs left over.
He's only wanting one or two individual chips to work with.
That won't "start production this year" in anyone's book. Even if you could somehow magically get enough stock the problem is that you need your first prototype tested and then hopefully a production version etc and that's assuming the P2 works first go as we are hoping.

We should be able to deliver boards to forum members soon, if the chip works.
You guys need to make an 'unboxing' video of the glob arrival and testing.
We forumistas would probably pay good money to watch that.
Hmmmm...
Maybe we'll do that: Solder caps on P2D2, solder chip on P2D2, connect PropPlug to P2D2. Apply power. Run PNut.exe. Do ctrl-G to check for life. If okay, download an NTSC program, since only one pin is needed for display. Make current measurements on VDD and VIO's. Have some neat analog I/O demo ready.

Do OnSemi do any testing on these first parts ?
ie do you start with a part that has passed at least some probe tests ?

These prototypes will have passed the OnSemi test program, which uses umpteen scan chains in TEST=high mode to run a bunch of patterns to assure that no defect in the digital core exists. I just finished an additional test program that they will (hopefully) incorporate into their overall test. I'll attach it. It was a tedious PAIN to write.

Some of those look to be quite tough analog tests ?
Is their tester signal/noise (includes decoupling) going to be good enough for those sorts of tests ? (ie not give you false fails)

The tester adds 100pF of capacitance per pin, so I developed the tests using a 100pF load. I don't have a real chip, yet, so I used the latest test chip which provided two real I/O pins. I got that working and then recoded for 8 pins per cog (8 cogs run in parallel, testing 8 pins each).

That's extremely generous of you. I would have been more than happy to pay $100 to have one to play with over the Christmas holidays.
Yes indeed. The world would be a better place if more organizations were to emulate the way Parallax operates.

There are two hemispheres and thus two springs
There are also many release milestones.. Rev A silicon, ( Rev B silicon ..) Production release, Production Volumes
5 more weeks to first silicon. :thumb:

Jef,
You probably should start by talking to Publison, assuming you're in USA, to get a sample board posted out - https://forums.parallax.com/discussion/168697/us-distribution-of-peters-p2d2-board/p1

It sure will be great to see it up and running. I've got a real good feeling about this version .

I do.
However, doing that can go anywhere too. Ranges from terrible to completely awesome!
A private stream might make sense.
Either way, it would be great to see.
