Maxim Integrated DS28E10P+TR Secure Authenticator

The DS28E10P+TR from Maxim Integrated is a robust, secure authenticator that provides a cost-effective solution for ensuring the authenticity and integrity of products. This compact device leverages Maxim's expertise in security and integrated circuits to provide a high level of protection against counterfeiting, unauthorized usage, and other malicious activities.

At the heart of the DS28E10P+TR is a unique, factory-programmed 64-bit registration number, which serves as a foundational element for the chip's security features. This unique ID cannot be altered, ensuring that each chip is distinct and traceable back to its origin. The device incorporates a SHA-1 hash-based message authentication code (HMAC) algorithm, which is a widely recognized and secure method of verifying the authenticity of a message. This ensures that communication between the DS28E10P+TR and the host system is protected against tampering and spoofing attacks.

Designed for ease of integration, the DS28E10P+TR operates over a single-contact 1-Wire® interface, which simplifies the connection to a host microcontroller. This interface not only reduces the number of necessary pins but also enables the authenticator to draw power directly from the data line, minimizing the need for additional power supply lines.

The device's compact form factor, available in a 6-pin TSOC package, makes it an ideal choice for space-constrained applications. It is also available in tape and reel packaging (designated by the "TR" suffix), which facilitates efficient, automated placement during the manufacturing process, making it well-suited for high-volume production.

Typical applications for the DS28E10P+TR include accessory and peripheral authentication, printer cartridge identification, medical device authentication, and any other application where proving the legitimacy of a product or component is crucial. By incorporating the DS28E10P+TR into their designs, manufacturers can protect their brand integrity, safeguard their revenue streams, and ensure customer satisfaction by preventing the use of counterfeit or unauthorized products.

Overall, the DS28E10P+TR is a testament to Maxim Integrated's commitment to providing secure, reliable, and easy-to-use solutions for product authentication challenges across a broad range of industries.
