DS28E01P-100+T Description

Short technical summary and product information.

The DS28E01P-100+T from Analog Devices (formerly Maxim Integrated) is a 1Kbit EEPROM with integrated challenge-and-response authentication security using the SHA-1 algorithm. This device is partitioned into four 256-bit pages, with one page configurable for EPROM emulation mode. It communicates via the single-contact 1-Wire bus, utilizing its unique 64-bit ROM registration number as an address.

 

Key features include an on-chip SHA-1 engine capable of processing secrets and generating 160-bit Message Authentication Codes (MACs). Write access requires knowledge of a secret and the ability to compute a valid MAC. The device supports user-programmable page write protection and an EPROM emulation mode for Page 1. It operates from a 2.85V to 5.25V supply range across an industrial temperature range of -40°C to +85°C.

 

This EEPROM is suitable for applications requiring secure data storage and authentication, such as printer cartridge configuration, medical sensor calibration, and system intellectual property protection. The DS28E01P-100+T is supplied in a 6-lead TSOC surface-mount package, designed for efficient integration into various electronic systems.
