DS28E15P+T Description

Short technical summary and product information.

The DS28E15P+T from Analog Devices is a secure authenticator IC designed for robust embedded security applications. It combines strong bidirectional challenge-and-response authentication based on the FIPS 180-3 specified Secure Hash Algorithm (SHA-256) with 512 bits of user-programmable EEPROM for nonvolatile data storage.

 

This device features a unique, factory-programmed 64-bit ROM identification number (ROM ID) that serves as a fundamental input for cryptographic operations and an electronic serial number. The 512-bit EEPROM is partitioned into two 256-bit pages and offers user-programmable, irreversible protection modes, including authentication, write protect, read protect, and OTP/EPROM emulation.

 

The DS28E15P+T communicates over a minimalist 1-Wire interface, reducing control, address, data, power, and programming signals to a single data pin. This simplifies interface complexity and lowers costs. The IC is supplied in a 6-TSOC package suitable for surface mounting.

 

Key features include ±8kV HBM ESD protection. Applications include authentication of consumables and secure feature control, providing a secure method for validating attached devices and protecting user memory from unauthorized modification.
