DS2401P+T&R

Specialized ICS Overview

The DS2401P+T&R is a silicon serial number IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 6-TSOC surface-mount package. It provides an absolutely unique 64-bit registration number consisting of an 8-bit family code (01h), a 48-bit serial number, and an 8-bit CRC tester. The device utilizes the 1-Wire interface protocol, requiring only a single data lead and ground return for communication at speeds up to 16.3kbps. Operating within an extended voltage range of 2.8V to 6.0V and an industrial temperature range of -40°C to +85°C, it features zero standby power consumption.

Specialized ICS Feature Summary

• Guaranteed Unique 64-Bit ROM ID Chip for Absolute Traceability
• Minimalist 1-Wire Interface Reduces Control, Address, Data, and Power to a Single Pin
• Built-In Multidrop Controller Ensures Compatibility with Other 1-Wire Net Products
• Extended 2.8V to 6.0V Voltage Range with Zero Standby Power Required

Specialized ICS Applications

• PCB Identification
• Network Node ID
• Equipment Registration

Specialized ICS Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and lead configuration. The 'T&R' suffix indicates Tape and Reel packaging, while the '+' denotes a lead-free/RoHS-compliant package. Confirm that the 6-TSOC package variant aligns with your board layout requirements before procurement.

Specialized ICS Selection Notes

Select the DS2401P+T&R when a compact surface-mount solution is required for absolute device identification. Ensure the system design accommodates the 1-Wire open-drain bus architecture with appropriate pullup resistors. Verify that the operating voltage remains within the 2.8V to 6.0V range and that the industrial temperature rating meets environmental constraints.

Specialized ICS Part Context

This component belongs to the DS2401 series of silicon serial numbers, which serve as low-cost electronic registration codes. It acts as an upgrade to the DS2400, offering full reverse compatibility while adding multi-drop capability for multiple devices on a single data line. The TSOC package allows for standard assembly equipment handling.

Specialized ICS Replacement Considerations

The DS2401A+T&R is a compatible alternative within the same series. Note that the DS2401A supports different pullup resistance ranges and responds to Match ROM/Skip ROM commands differently than the standard DS2401.
