Overview

The DS2401Z+T&R is a Silicon Serial Number that provides a unique, factory-lasered 64-bit registration number for electronic systems. It utilizes the 1-Wire interface, requiring only a single data lead and a ground return for bidirectional communication, while drawing zero power when in standby.

Why Choose This Part

The device features a unique 64-bit ID including an 8-bit family code that ensures no two parts are alike globally. It operates over a wide voltage range of 2.8V to 6V and offers extreme power efficiency with zero standby power consumption.

Applications

PCB Identification
Permanently identifies printed circuit boards to track manufacturing history and revision levels.
Network Node ID
Provides a unique address for nodes in a distributed network using the built-in multidrop controller.
Equipment Registration
Serializes high-value equipment to prevent unauthorized cloning and manage warranty tracking.
Access Control
Acts as a low-cost electronic key for securing industrial or commercial hardware access.

Getting Started

To interface with the DS2401, implement the 1-Wire protocol on a host microcontroller bit-bang GPIO or use a dedicated 1-Wire master IC. A single 4.7k ohm pull-up resistor is required on the data line to facilitate communication and provide power via the parasitic supply.
