Maxim Integrated's DS28E22P+ Secure Authenticator

The DS28E22P+ from Maxim Integrated is a robust secure authenticator that provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security. Designed to ensure the authenticity and integrity of products, this device is ideal for protecting your supply chain, preventing counterfeiting, and ensuring the safety and compliance of end products.

With its built-in 1-Wire interface, the DS28E22P+ allows for simple and cost-effective communication through a single data line, plus ground. This feature enables easy integration into designs where space and pin count are at a premium. The 1-Wire protocol also supports multi-drop configurations, allowing multiple DS28E22P+ devices to be connected on the same bus for efficient use in complex systems.

The device's strong security features are built upon a FIPS 180-compliant SHA-256 cryptographic engine, paired with a unique 64-bit registration number that ensures a globally unique identity. The ECC-P256 public/private key capabilities enable the generation of high-security, single-use authentication signatures, which are vital for protecting intellectual property and securing supply chains against counterfeit products.

Furthermore, the DS28E22P+ offers secure, user-programmable and lockable EEPROM storage, which can be used to store application data, keys, and certificates. This capability is essential for maintaining the confidentiality and integrity of sensitive information throughout the product's lifecycle.

For ease of deployment, Maxim Integrated provides a comprehensive support ecosystem for the DS28E22P+, including evaluation kits, software libraries, and thorough documentation. This support ensures that designers can rapidly implement the DS28E22P+ into their systems with minimal development time and resources.

Whether you're designing medical devices, consumer electronics, or industrial equipment, the DS28E22P+ offers a cost-effective solution for protecting your investments and your customers. Its advanced security features, ease of use, and robust design make it an excellent choice for any application requiring reliable authentication and data protection.
