DS2401AZ+

Specialized ICS Overview

The DS2401AZ+ is a silicon serial number integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a guaranteed unique 64-bit ROM ID for absolute traceability, comprising an 8-bit family code (01h), a 48-bit serial number, and an 8-bit CRC tester. The device utilizes a minimalist 1-Wire interface requiring only a single data pin and ground return. Operating within a voltage range of 3V to 5.25V and an industrial temperature range of -40°C to +85°C, it draws a maximum input load current of 5µA. The component is housed in a SOT-223-3 surface-mount package.

• Minimalist 1-Wire Interface Reduces Control, Address, Data, and Power to a Single Pin
• Extended Voltage Range: 3V to 5.25V with Zero Standby Power Required
• Industrial Temperature Range: -40°C to +85°C

Specialized ICS Applications

• PCB Identification
• Network Node ID
• Equipment Registration

Specialized ICS Procurement Notes

Verify the specific ordering suffix 'AZ+' against official documentation to confirm lead-free/RoHS compliance status and package type. Confirm that the SOT-223-3 package matches the required footprint for the design. Ensure the pullup resistor values align with the DS2401A electrical characteristics specified in the datasheet.

Specialized ICS Selection Notes

Select the DS2401AZ+ when a unique silicon serial number is required for asset tracking or authentication. This variant is suitable for applications needing a surface-mount SOT-223 package. Consider the DS2401A+ specifications regarding pullup resistance (300Ω to 2.2kΩ) if designing for short line lengths or higher speed communication up to 16.3kbps.

Specialized ICS Part Context

The DS2401 series serves as an electronic registration number providing a unique identity via a minimal electronic interface. It is an upgrade to the DS2400, offering reverse compatibility while adding multi-drop capability for multiple devices on a single data line. The AZ+ designation indicates a specific package and compliance configuration within the broader DS2401 product family.

Specialized ICS Replacement Considerations

The DS2401Z+ is a direct functional equivalent in the same SOT-223 package. For through-hole requirements, the DS2401+ in TO-92 is available. Verify that any replacement maintains the 1-Wire protocol compatibility and meets the specific voltage and temperature operating ranges of the application.
