DS28E15Q+T Description

Short technical summary and product information.

The DS28E15Q+T from Analog Devices is a DeepCover Secure Authenticator designed for robust security applications. It combines crypto-strong bidirectional secure 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 supports user-programmable and irreversible protection modes, including authentication, write protect, read protect, and OTP/EPROM emulation.

 

The DS28E15Q+T communicates over a single-contact 1-Wire bus, reducing interface complexity by consolidating control, address, data, power, and programming signals to a single pin. It offers ±8kV HBM ESD protection.

 

Packaged in a 6-TDFN (3x3) surface-mount package, this authentication chip is suitable for applications requiring secure feature control and authentication of consumables.
