Product Details
DS2411P+ - 1-Wire Silicon Serial Number
DS2411P+ from Analog Devices / Maxim Integrated is a factory-programmed silicon identifier with a unique 64-bit registration number and a 1-Wire interface. This ordering option uses the 6-TSOC (6-SMD J-lead) package.
Technical values and ordering details were checked against the Analog Devices DS2411 Rev. 4 data sheet and current distributor information.
Overview
DS2411 adds an immutable electronic identity to a PCB, module or network node. Its 64-bit ROM contains an 8-bit family code, a unique 48-bit serial number and an 8-bit CRC. A host reads the identifier through the multidrop-capable 1-Wire bus.
Key Advantages
Factory-lasered and tested registration number; no programming step is needed.
The 1-Wire interface connects to a single MCU port plus ground and VCC.
Multiple DS2411 devices can share one 1-Wire network.
Standby supply current is specified below 1 µA.
Feature Summary
Includes family code 01h, a 48-bit serial number and CRC.
1-Wire communication operates up to 15.4 kbit/s.
DS2411 supports communication up to 125 kbit/s.
External VCC operating range is 1.5 V to 5.25 V.
Package & Footprint
The P ordering code uses the 6-lead TSOC surface-mount package. This + option is supplied in tubes; the distributor standard tube break is 120 units.

Replacement Considerations
DS2411P+T&R uses the same DS2411 silicon function but differs in package or shipping media. Confirm footprint, pin mapping, assembly format and order quantity before substitution.
DS2411A is functionally related but is parasitically powered and has different electrical characteristics. It is not an unconditional drop-in replacement.
Manufacturer Information
Analog Devices supports the former Maxim Integrated 1-Wire portfolio. DS2411 is listed as recommended for new designs.
Applications
Provides a permanent serial number for board tracking.
Lets a host identify attached modules or accessories.
Supports manufacturing and service traceability.
Identifies nodes sharing a multidrop 1-Wire bus.
Quality & Authenticity
Match the full ordering code and package marking to the purchase record. During incoming inspection, read the ROM, verify its CRC and reject duplicate identifiers within the controlled population.
FAQ
Can the serial number be rewritten?
No. The registration number is factory programmed in ROM.
Does DS2411 need VCC?
Yes. DS2411 uses an external supply; DS2411A is the no-VCC variant.
Can several devices share one bus?
Yes. The built-in multidrop controller supports multiple 1-Wire devices.
Is the package image ready?
No. The registered package JPG must be added before publication.
Engineering Notice
Validate pull-up resistance, bus capacitance, reset/presence timing, overdrive timing and power-up delay on the complete network. Use the exact package drawing and latest Analog Devices data sheet for PCB approval.
