DS28E15G+U

Specialized ICS Overview

The DS28E15G+U is a DeepCover Secure Authenticator featuring a 512-bit user-programmable EEPROM and SHA-256 authentication. It utilizes a symmetric-key-based bidirectional secure challenge-and-response model compliant with FIPS 180-3. The device includes a unique factory-programmed 64-bit ROM ID for cryptographic operations and electronic serial numbering. It communicates via the single-contact 1-Wire bus at overdrive speed, reducing interface complexity to a single data pin. The component operates within a voltage range of 3.3V ±10% (-40°C to +85°C) and provides ±8kV HBM ESD protection.

Specialized ICS Feature Summary

• Integrates 512-bit EEPROM partitioned into two 256-bit pages with SHA-256 read/write authentication.
• Supports user-programmable, irreversible EEPROM protection modes including authentication, write protect, read protect, and OTP/EPROM emulation.
• Features a unique 64-bit factory-programmed ROM ID used as a fundamental input for cryptographic operations.
• Utilizes a minimalist 1-Wire interface that consolidates control, address, data, power, and programming signals onto a single pin.

Specialized ICS Applications

• Authentication of consumables
• Secure feature control

Specialized ICS Procurement Notes

Verify the specific suffix 'G' against official documentation to confirm package type and environmental compliance status. Confirm availability through authorized Analog Devices or Maxim Integrated distributors, as supply levels may vary. Ensure the ordering part number matches the required package configuration for your PCB layout.

Specialized ICS Selection Notes

Select this component when bidirectional security and nonvolatile storage are required on a single-wire network. The DS28E15 is suitable for applications needing strong authentication against unauthentic hosts. Consider the 2-pin SFN, 6-pin TDFN-EP, or 6-pin TSOC packages based on space constraints. Ensure the host system supports the 1-Wire protocol at overdrive speeds.

Specialized ICS Part Context

The DS28E15 belongs to the DeepCover embedded security solution family designed to cloak sensitive data under multiple layers of advanced physical security. It combines crypto-strong authentication with standard EEPROM functionality. The 'DS28E15G+U' designation indicates a specific variant within this series, likely denoting package and tape/reel specifications.

Specialized ICS Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the DS28E15 series. Verify that any substitute maintains the same 1-Wire overdrive compatibility and SHA-256 authentication capabilities. Cross-reference package dimensions if replacing with different suffix variants.
