The RockerBox contain 193 double SHA low-power, high-performance engines, which can be chained to any number of other RockerBox ASICs via a proprietary serial interface tailored for this purpose. 1.1 Key Features Double SHA-256 cores Serial Interface  193 fully-unrolled engines, each performs a single hash per cycle  Supports any number of devices on a board  Seamlessly adding or reducing devices  Engine integrity test support—BIST   Up to 0.2THash/s in typical process corner Addressing scheme to support ASIC broadcasting transactions  Low pin count – clock, data in, data out  Low power consumption 0.3W/GHps  Can run up to 50 MHz continuous data rate Power Efficient Thermal Sensors and thermal shutdown  The RockerBox chip can work in core voltages 550—800mV  Two thermal sensors configures to eight levels. Ranges 90 to 125 °C equally spaced.  Each engine can be shutdown for power save purposes  Thermal sensors can invoke engine shutdown upon over-heating, to prevent ASIC meltdown Configurable PLL  Supports core frequencies from 500—1500 MHz.
