How many leads does the chip have and what package type ?
INMOSI, INSCK - SPI inputs
INMISO - SPI output (to controller)
Is there a SPI load pin also? How is a frame clocked in
without a load signal?

IOVDD - feed it with 1.8 V
--
This is for IO with the processor I guess? Can it be 3V3 also?
INCLK - input clock (in case if internal oscillator not works)
--
What clock frequency?
INMOSI, INSCK - SPI inputs
INMISO - SPI output (to controller)
--
Whats are the word lengths used by the SPI link?
16-bit words? 32-bit word?
Have a test jig almost ready. How can I past images to the forum?

I could do this. I work for a university, have access to everything needed.
/full disclosure though, I'm super busy now that its summer and wouldn't be able to work on it super fast full time. And im moving soon.

0.5mm pin pitch? I already can hear those curses of person who will be solder that 
IMHO better option is to make simple prototype PCB with thermotransfer method. Design + producing will take 1 hour at most. Less hassle and more reliability.
I wish I had more time to join to those tests. I have everything is needed execpt time
Although I'm interested in some chips for testing. I"m planning to design a miner based on those chips. And if everything will be looking good byuing chips in bulk from tytus. I already have some PCB design and code for uC controller but definitely I will not end this in few days

I agree fully. Dead-bugging this chip could prove to be very hard.
Better to make small adapter PCB to hold the chip that can be
connected easily to a processor board.
Can the pinout be found anywhere? I'm willing to design an adapter then,
should not take more then a few hours....

Thanks, just got it from a friend. Firefox didn't allow me to

schematic shape right now...

LOL, about 75% of the pins are VDD:)

Great to see the chip wars continue unabated. The second half of this year is shaping up to be the best yet in the race to hashing supremacy.

If its not mining bitcoins, its failed.

I'll take a few chips. PM me for contact details.
I have access to an LPKF ProtoLaser, various HF oscopes, lab PSU's and clock generators.

I have the tools and experience and willing to alpha test your chips. Willing to sign NDA if u want to

bitfury, about your bet, it was edited by BitBet staff right? You did not write this part?
Quote
BitFury's ASIC will be demonstrated to mine Bitcoin either publicly, in an open to the public event announced at least two weeks in advance, or privately as confirmed by unaffiliated, well respected members of the community (this specifically excludes known shills such as Luke-jr) and will consume less than 1 W per GH/s for powering the chip and the board (excluding any cooling appliances). CHIP ZARABOTAET I BUDET POTREBLYAT < 1 W / GH/s. Initiated by Bitfury, who placed the first Yes bet.
Right. I haven't written about verification procedure at all. I simply thought that my word would be enough, as it would be evident later that I lied in a very simple way, and this bet amount is too small compared to reputation loss. Now I even offered 250 BTC as hard guarantee that I won't lie with verification results - it was declined... Anyway independent testing is nice idea.
I really worked a lot on chip and had no time to visit forum, etc. during that period... Designing this chip took almost 8 month of life continuously without rest. So I don't know much about buzz that happened recently and don't have time to read kilotons of posts.
2 dropt: test bed - depends on inductance ... I worry that at 0.6 V pulsations in power would dramatically impact performance. Thanks for your interest.
June 08, 2013, 02:14:18 AM
I too am raising interest in validating your design bitfury. EE credentials with full digital/embedded design lab (Bench DC PSU, Waveform Gens, 4ch DSOs, etc.) at my disposal. Can dead-bug, or I might have a QFN48 test bed laying around somewhere.

Yes, I need a few chips for my this part of the world.

I can test this chip and make project of working mining ring.
