The DS28E02Q-W01+2T from Maxim Integrated is a robust, high-security EEPROM with an integrated SHA-256 engine, designed to provide a secure storage solution with authentication capabilities. This product is a part of Maxim's extensive portfolio of secure memory devices, which are engineered to meet the demands of applications requiring stringent data protection and integrity verification.

At the heart of the DS28E02Q-W01+2T lies a 1-Wire interface, which simplifies the connectivity by using a single bus line for communication, providing a cost-effective solution for systems where pin count or space is at a premium. This interface also allows for the device to be powered directly from the data line ("parasite power"), eliminating the need for an external power supply.

With a memory capacity of 1024 bits of EEPROM storage, users can securely store sensitive data, such as cryptographic keys, configuration settings, or certificates. The integrated SHA-256 hash function ensures that any stored data is protected against tampering and unauthorized access, by providing a secure way to verify the integrity and authenticity of the data.

The DS28E02Q-W01+2T also features a unique, factory-programmed 64-bit registration number, which ensures a unique identity for each device. This feature is particularly useful for tracking and managing individual devices in a distributed system, and for preventing counterfeiting in supply chains.

Designed for applications that require high security and reliability, such as medical devices, financial systems, and secure access controls, the DS28E02Q-W01+2T operates over a wide temperature range (-40°C to +85°C), ensuring performance in a variety of harsh environments.

Maxim Integrated's commitment to quality and security is evident in the DS28E02Q-W01+2T, making it an ideal choice for designers and engineers looking for a secure, reliable, and easy-to-integrate memory solution for their next project.
