DS28E15G+T

Specialized ICS Overview

The DS28E15G+T is a DeepCover Secure Authenticator featuring a 512-bit user-programmable EEPROM and SHA-256 authentication. It operates on the 1-Wire bus at overdrive speed, utilizing a symmetric-key-based bidirectional security model for challenge-and-response verification. The device includes a unique factory-programmed 64-bit ROM ID and protected memory for secrets. It supports irreversible protection modes such as read/write protection and OTP emulation. Operating within a 3.3V ±10% range (-40°C to +85°C), it provides ±8kV HBM ESD protection in a 2-pin SFN package.

Specialized ICS Feature Summary

• Integrates 512-bit EEPROM partitioned into two 256-bit pages with SHA-256 authentication for reads and writes.
• Employs a symmetric-key-based bidirectional secure authentication model using a high-bit-count user-programmable secret.
• Features a unique factory-programmed 64-bit identification number (ROM ID) serving as an electronic serial number.
• Supports user-programmable and irreversible EEPROM protection modes including authentication, write protect, read protect, and OTP/EPROM emulation.

Specialized ICS Applications

• Authentication of Consumables
• Secure Feature Control

Specialized ICS Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm RoHS compliance status via current documentation. Ensure storage conditions align with manufacturer specifications to maintain data integrity. Check for specific ordering suffixes that may affect packaging or temperature grades before procurement.

Specialized ICS Selection Notes

Select this component when bidirectional SHA-256 authentication is required for 1-Wire networks. The 512-bit EEPROM capacity suits applications needing moderate nonvolatile storage with strong access control. Consider the 2-pin SFN package for space-constrained designs requiring minimal interface complexity.

Specialized ICS Part Context

The DS28E15 belongs to the DeepCover Secure Authenticator family, designed to protect sensitive data through advanced physical security layers. It combines cryptographic functions with embedded memory, offering a robust solution for securing application data against unauthorized access or modification in embedded systems.

Specialized ICS Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts support identical 1-Wire overdrive speeds, SHA-256 capabilities, and EEPROM capacities. Verify package compatibility and operating voltage ranges match the original design requirements.
