DS2411R+T&R

Specialized ICS Overview

The DS2411R+T&R is a silicon serial number integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a unique, factory-tested 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 operates on the 1-Wire protocol with a supply voltage range of 1.5V to 5.25V and supports communication speeds up to 15.4kbps in standard mode and 125kbps in overdrive mode. Packaged in SOT-23-3 format, it features standby current below 1μA and operates within a temperature range of -40°C to +85°C.

Specialized ICS Feature Summary

• Unique 64-bit Registration Number: Factory laser-trimmed 48-bit serial number with 8-bit family code and 8-bit CRC for guaranteed uniqueness.
• Low Power Consumption: Standby supply current is less than 1μA when idle.
• Dual Speed Communication: Supports standard speed up to 15.4kbps and overdrive mode up to 125kbps via the 1-Wire interface.
• Multidrop Capability: Built-in controller allows multiple devices to reside on a common 1-Wire network.

Specialized ICS Applications

• PCB Identification
• Network Node Authentication
• Equipment Registration

Specialized ICS Procurement Notes

Verify that the specific order includes the 'T&R' suffix to confirm Tape & Reel packaging. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the component grade meets the required operational temperature range of -40°C to +85°C. Check RoHS compliance status as indicated by the '+' suffix in the part number.

Specialized ICS Selection Notes

Select the DS2411R variant specifically when an external VCC power supply pin is required, distinguishing it from the DS2411A which lacks this pin. Ensure the system design accommodates the 1200µs power-up delay before initial 1-Wire communication can begin. Verify that the microcontroller interface supports the open-drain 1-Wire protocol requirements.

Specialized ICS Part Context

This component belongs to the DS2411 series of silicon serial numbers. The 'R' designation indicates the SOT-23-3 surface-mount package. The '+T&R' suffix denotes lead-free/RoHS-compliant packaging in a tape and reel configuration. It serves as a low-cost electronic identity solution for embedded systems requiring unique hardware identification.

Specialized ICS Replacement Considerations

The DS2411AR+T&R is a functional equivalent but lacks the external VCC input pin. Other packages such as TSOC or Flip Chip variants exist but require different footprint designs. Direct pin-to-pin replacement is limited to other DS2411 parts in the SOT-23-3 package.
