DS2411X

Specialized ICS Overview

The DS2411X is a silicon serial number device from Analog Devices Inc./Maxim Integrated, housed in a 4-FlipChip (0.69x1.09) surface-mount package. It provides a unique, factory-lasered 64-bit registration number comprising an 8-bit family code, a 48-bit serial number, and an 8-bit CRC tester. The component operates within a temperature range of -40°C to +85°C and communicates via the 1-Wire protocol at speeds up to 15.4kbps, with overdrive mode supporting 125kbps. Designed for multidrop networks, it features low standby current and ensures absolute uniqueness across all units.

Specialized ICS Feature Summary

• Unique 64-Bit Registration Number: Factory-lasered 48-bit serial number, 8-bit family code (01h), and 8-bit CRC; guaranteed no two parts are alike.
• Multidrop Capability: Built-in controller allows multiple devices on a common 1-Wire network, identified by the 8-bit family code.
• Dual Speed Communication: Standard speed up to 15.4kbps and Overdrive mode boosting speed to 125kbps.
• Low Power Consumption: Standby current is less than 1μA.

Specialized ICS Applications

• PCB Identification
• Network Node Authentication
• Equipment Identification/Registration

Specialized ICS Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm RoHS compliance status and tape-and-reel packaging configuration. Ensure the selected variant matches the required voltage supply constraints, as the DS2411 series includes variants with and without external VCC inputs that have different electrical specifications.

Specialized ICS Selection Notes

Select the DS2411X when a compact Flip-Chip footprint is required for surface-mount assembly. Confirm whether the application requires an external power supply (DS2411) or parasite power operation (DS2411A), as these variants differ in operating voltage ranges and input capacitance. Verify compatibility with existing 1-Wire bus masters regarding pull-up resistance and timing requirements.

Specialized ICS Part Context

The DS2411X belongs to the DS2411 silicon serial number family, which also includes SOT23-3 and TSOC packages. It serves as a low-cost electronic identity solution using the 1-Wire protocol. The 'X' designation specifically denotes the 4-pin Flip-Chip package form factor, distinct from the lead-free/RoHS-compliant '+' suffix used in other package types within the same product line.

Specialized ICS Replacement Considerations

Direct replacements include other DS2411 variants such as DS2411P+ (TSOC) or DS2411R+T&R (SOT23-3). Note that pin configurations and physical dimensions differ significantly between package types. Ensure the substitute supports the required communication speed and voltage conditions.
