DS2411R-C01+T

Specialized ICS Overview

The DS2411R-C01+T 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 tester. 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. Packaged in SOT-23-3 with Tape & Reel delivery, it features standby current below 1μA and includes a built-in multidrop controller for network compatibility.

Specialized ICS Feature Summary

• Unique 64-bit Registration Number: Includes 8-bit family code, 48-bit serial number, and 8-bit CRC.
• Low Power Consumption: Standby current is less than 1μA.
• Multidrop Capability: Built-in controller allows multiple devices on a common 1-Wire network.
• Dual Speed Modes: Supports standard speed up to 15.4kbps and overdrive mode up to 125kbps.

Specialized ICS Applications

• PCB Identification
• Network Node Registration
• Equipment Identification

Specialized ICS Procurement Notes

Verify the specific ordering suffix C01 against official documentation to confirm if it denotes a custom serial number assignment or specific manufacturing lot variation, as standard datasheets list DS2411R+T&R for the SOT-23-3 package. Confirm RoHS compliance status associated with the '+' designation. Ensure the supplier source is authorized to guarantee part authenticity given the discontinued status of some variants in general distribution channels.

Specialized ICS Selection Notes

Select the DS2411R variant when an external VCC power supply is required, allowing operation down to 1.5V, unlike the DS2411A which relies on parasite power starting at 3V. The SOT-23-3 package is suitable for surface-mount applications requiring a compact footprint. Consider the overdrive mode requirement if higher bus throughput is necessary, noting that timing parameters differ significantly between standard and overdrive speeds.

Specialized ICS Part Context

The DS2411 belongs to the Maxim Integrated 1-Wire silicon serial number family. It serves as a slave device on a 1-Wire bus, providing absolute identity to microcontrollers. The 'R' in the part number typically indicates the SOT-23-3 package configuration. This component is functionally equivalent to other members of the series but is distinguished by its specific packaging and voltage operating range requirements.

Specialized ICS Replacement Considerations

The DS2411AR+T&R is a direct functional substitute in the same SOT-23-3 package, though it lacks the external VCC pin and operates from 3V to 5.25V. For systems requiring the 1.5V to 5.25V range, no direct non-VCC replacement exists without hardware modification. Other 1-Wire ROM devices like the DS2413 are not pin-compatible or functionally identical due to different memory architectures.
