DS2411R+U

Specialized ICS Overview

The DS2411R+U is a silicon serial number integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a unique, tested 64-bit registration number consisting of an 8-bit family code (01h), a 48-bit serial number, and an 8-bit CRC checksum. The device operates within 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 via the 1-Wire protocol. It is housed in a surface-mount SOT-23-3 package and functions as a slave device on a multidrop network.

Specialized ICS Feature Summary

• Unique 64-bit ROM containing an 8-bit family code, 48-bit serial number, and 8-bit CRC
• Low standby current consumption of less than 1µA
• Supports Overdrive Mode for communication speeds up to 125kbps
• Multidrop controller capability allows multiple devices on a common 1-Wire network

Specialized ICS Applications

• PCB identification
• Network node registration
• Equipment identification

Specialized ICS Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status indicated by the '+' suffix. Check for discontinued status or limited availability from suppliers. Ensure ordering specifications match the required SOT-23-3 package and temperature range.

Specialized ICS Selection Notes

Select the DS2411R+U when an external VCC power supply is required for operation below the typical 1-Wire voltage range. This model supports a minimum operating voltage of 1.5V, unlike the DS2411A which requires a minimum of 3.0V. Choose this part for applications needing a dedicated power pin alongside the single data line interface.

Specialized ICS Part Context

The DS2411R+U belongs to the DS2411 series of silicon serial numbers. The 'R' suffix denotes the SOT-23-3 package type, while '+U' indicates lead-free/RoHS-compliant packaging in a strip configuration. It is functionally equivalent to other variants in the DS2411 family but differs in physical package and specific electrical parameters related to its power supply requirements.

Specialized ICS Replacement Considerations

The DS2411P+ serves as a package alternative using TSOC-6. The DS2411A variant offers similar functionality but operates without an external VCC input, requiring a higher minimum voltage of 3.0V.
