Overview

The DS2401P+ is a silicon serial number IC that provides a unique, factory-lasered 64-bit registration number for electronic systems. It uses the 1-Wire interface to communicate address, data, and power over a single signal line, enabling traceable identification with minimal board footprint and interconnect requirements.

Why Choose This Part

The device features a unique 48-bit serial number and an 8-bit CRC, ensuring data integrity without complex software overhead. Its parasitic power capability allows it to operate with zero standby power, drawing all necessary current (typically 5uA during operation) directly from the data line.

Applications

PCB Identification
Permanently identify circuit board revisions and manufacturing batches for lifecycle tracking.
Network Node ID
Provide a globally unique hardware address for devices on distributed 1-Wire or RS-485 networks.
Equipment Registration
Securely register peripheral attachments or consumable components to a host system to prevent unauthorized cloning.
Inventory Management
Enable automated tracking of modular hardware components within a larger enclosure or rack system.

Key Specifications

Type Silicon Serial Number
Applications PCB, Network Node, Equipment Identification/Registration
Mounting Type Surface Mount
Package / Case 6-SMD, J-Lead
Supplier Device Package 6-TSOC

Getting Started

To integrate the DS2401P+, implement the 1-Wire protocol on any standard microcontroller GPIO using a single pull-up resistor. Developers can use the Maxim 1-Wire Public Domain Kit or existing Arduino and Linux OneWire libraries to perform the 'Read ROM' command and retrieve the 64-bit identifier.

Also Consider

ATSHA204A MCHPMicrochip Technology - Provides a unique ID alongside hardware-based SHA-256 authentication for higher security requirements.
