Innosilicon Announce the world 1st 28nm Litecoin ASIC and Reference Miners

The A1Craft (also referred to as A1) is a simple to use, custom developed with Bitmine, highly optimized ASIC hardware implementation of the Bitcoin block hashing algorithm with the highest power efficiency to-date. It is developed on 28nm HPP (High Performance Processes) from Global Foundries with innovative redundancy architecture to allow for server grid reliability.

The A1 has operation modes from low power to over-clocked high performance through adjustment of PLL output clock frequency and/or in combination with voltage adjustment. In the low power nominal mode, the computation clock & operational voltage decreases, thus total power consumption is reduced. In the turbo mode, the performance is pushed to the limit, which reaches to around 32GH/s, meanwhile the power consumption/heat is maximum.

Key Features:

  • Developed on 28nm using very low power design techniques and best efficiency.
  • Custom IC package with power bars for low voltage, high current feeding.
  • Configurable in daisy chain mode for distributed work with up to 253 ASICs.
  • Standard SPI interface with CS pin needed to enclose all useful SDI and SDO data.
  • 32 highly optimized hashing engines based on custom ASIC cells up to 1GHz.
  • Built-in redundancy architecture to allow for bad engines to be bypassed without affecting mining operation.
  • Flexibility to configure the PLL clock and computation performance.
  • Hashing power of 20GH/s in ultra-low power, 25 GH/s in nominal and up to 32 GH/s in Turbo mode.
  • Power usage of 0.56 W/GH in typical nominal and 0.75W/GH in typical Turbo mode.
  • Supply voltage of 0.78V in low power, 0.85 V in Turbo mode for version 1 ICs.
  • No need for special cooling, just regular top and bottom heat sinks plus fan cooling.

How to order:

Note that Innosilicon ASIC and official miners from Innosilicon that are being offered in stock for shipment now till the stock runs out, price is fixed and performance is ensured before shipment. Shipping and handling is extra and user will be encouraged to arrange its own pickup/shipping or being charged based on DHL rate if shipping is handled by Innosilicon.

Fraud Alert:

Dear customers,

Please be aware that all sale inquiries need to go through Innosilicon direct email contact (**

Lately some customers reported to us that someone used "live:inno.miner","live:shuppinnosiliconcomcn","live:maxigel.3" fake Skype accounts to ask for customer payment. That is a fraud! Please be aware that "live:inno.miner","live:shuppinnosiliconcomcn","live:maxigel.3" fake Skype accounts are not our Skype accounts and DO NOT pay anyone through Skype request. Without correct Innosilicon email address (**, you may risk being cheated.

(1) Please be careful to check our website and confirm with our official sources before you pay. For payment process, please check here.
(2) We sell directly through our website. We don't have any so-called reseller globally. Please visit
(3) Don't send money other than Innosilicon account.

We hope every customer has a great user experience with our miner. Should there be any question, feel free to contact us via here.
