DS2401AX1-102-0D2#

Specialized ICS Overview

The DS2401AX1-102-0D2# is a silicon serial number integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a unique, factory-lasered 64-bit registration number consisting of an 8-bit family code, a 48-bit serial number, and an 8-bit CRC tester. The device operates on the 1-Wire protocol, requiring only a single data pin and ground for communication and power. It supports a supply voltage range of 2.8 V to 6.0 V and functions within an industrial temperature range of -40°C to +85°C. The component is housed in a compact 2-FlipChip (1.32x0.66) package.

Specialized ICS Feature Summary

• Unique 64-bit factory-lasered registration number with guaranteed uniqueness
• 1-Wire interface enabling single-pin communication and power delivery
• Operates on 2.8 V to 6.0 V supply voltage
• Industrial temperature rating from -40°C to +85°C

Specialized ICS Applications

• PCB identification
• Network node identification
• Equipment registration

Specialized ICS Procurement Notes

Verify the specific ordering suffix AX1-102-0D2# against official manufacturer documentation to confirm package type and electrical specifications. Ensure compatibility with existing board layouts due to the 2-FlipChip form factor. Confirm availability status as specialized ICs may have limited stock or longer lead times compared to standard components.

Specialized ICS Selection Notes

Select this component when a unique, non-volatile hardware identifier is required for security or tracking purposes. The 1-Wire interface minimizes microprocessor port usage. Consider the 2-FlipChip package dimensions (1.32x0.66 mm) for space-constrained surface-mount designs. Ensure the host system supports the 1-Wire protocol and can provide the necessary pull-up voltage within the 2.8 V to 6.0 V range.

Specialized ICS Part Context

The DS2401 series serves as a low-cost electronic registration code solution. It is an upgrade to the DS2400, offering multidrop capability on a common 1-Wire bus. The device eliminates standby power requirements by drawing power directly from the data line during communication. It is designed for applications requiring absolute, unique identification of devices or components.

Specialized ICS Replacement Considerations

The DS2400 is a compatible predecessor but lacks multidrop support. Verify that any replacement maintains the same 64-bit ROM structure and 1-Wire timing characteristics. Ensure the substitute component supports the required operating voltage and temperature range.
