Innosilicon Announce in 2013/14 the world 1st and best 28nm Bitcoin ASIC and Reference Miners

The A1Craft (also referred to as A1) is a world best BTC ASIC in 2013, simple to use, custom developed, 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. Its perfprmance is unrivaled by any existing product in the market

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.
