Is the 19th still a hard deadline?

Is the 19th still a hard deadline?

The deadline was set to leave me enough time to negotiate assembly contracts for the unsold chips. After clarifying with Bitmine, this can be done quite ad-hoc and does not need to be decided beforehand. Therefore, the deadline is extended to past the delivery date (OP was modified accordingly).

As for the documentation: I am currently reviewing the datasheet draft for the A1, which will be made available to the public before October 15th.

For the sample chips, do you already have them in hand?

I didn't see a direct answer, what is the exact specification of the packaging? Number of pins and package type?

Is it not clear from the OP? The chips offered here are the sample chips, i.e. those from the pilot run. So whether you order 2 chips to validate your design or 50 to build your first boards - those are the very first chips available.

Are there any developers or hardware manufacturers already committed to making boards or devices for these chips?

We are committing ourselves to an A1 Wasp (blade) and Hive (mother plane) design prototype and should be ready in January. Thread: https://bitcointalk.org/index.php?topic=299255.0.

Yes, but are they available today? I was thinking about ordering a few chips to build a board. But not going to bother with it unless you have them in hand at this moment. The way it's stated makes it seem as if they're available today, but without even information about what package type, number of pins, and pin out of the chip, makes it seem like they're not available today.

No, if you look from that perspective, there will be no sample chips but only an all-or-nothing first shot with enough wafers produced in the pilot run (like KnC did and succeeded). If there is a risk of chips not working as expected, it is covered by the CPP.

The preliminary datasheet will be released to the public by tomorrow, I'll post a related link here as soon as it is online.

How did you dig that out? That's not including the latest review results and most probably will be removed from that location soon, but ok: there it is Smiley

Not only documentation are went online. Bitmine start collecting order for chip https://bitmine.ch/?product=coincraft-ai-asic

Maybe they uploaded a wrong one Wink

Ah, no - my mistake then. I looked at only one location I knew I fixed and noticed it is still there, that's why I assumed it is an outdated version.

Nevertheless, as the water mark indicates, this is WIP and will be updated based on the community's feedback.

One thing I noticed immediately is a leftover from previous versions in section 4.6. Write the job to individual chip and start the computation. First the input interface was planned to have a queue of two work items, but was then modified to have a descriptor ring for 4 entries. So don't get confused by the last paragraph in this section and just ignore it.

If you find other issues or want to provide feedback, feel free to post it here or contact me via PM. I will collect and forward everything to Bitmine and help to establish the best chip frontend interface around Wink


Happy DIY designing!

This documentation is incomplete and not usefull at all. There is no pin numbering and no info about power pins...

Maybe not quite irrelevant Wink and added to TODO list:
Code:
TODOs for Coincraft A1 preliminary datasheet v0.1.A
* remove last paragraph in 4.6.
* provide pin numbering

No pin for I/O power? What voltage is accepted for I/O pins (and what voltage is at output?)  0,7V level shifter @ 20MHz dosn't sound promising…

That's what I mean:) Hopefully the inputs are 3V3 tolerant
and can be directly driven by a processor.

And the outgoing SPI signals have just the Vcore levels?

But at least we have a footprint, looks nice these power bars:)

Another thing,  flip chip package and plastic on top of the chip…  It's just wasting a potencial..

Does the chip has internal oscillator?
There is IN_CLOCK pin. Does the chip requires an external generator?
