RockerBox™—Overview
1
Overview
The document describes the features of the RockerBox chip, a Bitcoin optimized multiple double
SHA-256 engines ASIC.
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

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.
