IC/Module: DS2401 silicon serial number IC
DS2401 is a guaranteed unique 64-bit ROM ID chip that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (specifies communication requirements to reader).
Minimalist 1-Wire Interface
Intended to lower cost and interface complexity, DS2401 IC aboard the Unique ID Click Board™ communicates through a common 1-wire interface. It has a built-in multidrop controller that ensures compatibility with other 1-wire interface devices. 1-Wire Interface reduces control, address, data, and power to a single pin and communicates at up to 16.3kbps.
Robust Performance
The Unique ID Click Board™ operates on wide voltage and temperature ranges, which provide robust system performance. The extended voltage range is 2.8V to 6.0V and keeps the power consumption to minimal. It provides zero standby power.
