RE: [Coincraft A1 28nm ASIC] - Discussion Chip To Working Miner Group Buy
[RESERVED]
No, end of October is where the support material is guaranteed to be complete. This implies that it will be made available as open source as early as Bitmine has it - essentially DIY developers will have identical access to the relevant documents.
Since chip sales are part of their business, Bitmine has a vital interest to provide all available support to developers. That's why I am confident in this commitment enough to include the guarantee as part of the offer.
Code:
Product Description
Developed on 28nm HPP process from Global Foundries
Custom IC package with power bars for low voltage, high current feeding
Configurable in binary tree or daisy chain mode for distributed work with up to 4095 ASICs.
Standard I2C interface
Hashing power* of 20 GH/s in nominal and 40 GH/s in Turbo mode
Power usage* of 0.35 W/GH in low power, 0.6 W/GH in nominal and 1 W/GH in Turbo mode
Supply voltage* of 0.5V in low power, 0.65 V in nominal and 0.75 V in Turbo mode
Mass production available starting from the last week of November 2013
* Please note that while we took the highest possible care in doing accurate and conservative
simulations, the real performances of the final product could vary by a +/- 20% tolerance.

How I can miss that 
End of October. In this case, we have very limited time to design.
