Maxim Integrated DS2411X#U Silicon Serial Number

The Maxim Integrated DS2411X#U is a compact, secure silicon serial number chip that provides a unique identity to hardware devices. This chip is part of Maxim's renowned family of 1-Wire® devices, which are designed to provide a simple and cost-effective method of adding a unique ID to accessories, peripherals, or any electronic goods. The DS2411X#U is particularly useful for applications where a non-replicable identity is essential for authentication purposes or for tracking items through their lifecycle.

Encased in a small SOT-23 package, the DS2411X#U is equipped with a factory-lasered, 64-bit ROM that includes a unique 48-bit serial number, an 8-bit CRC checker, and an 8-bit Family Code (01h). This built-in uniqueness ensures that no two chips share the same identifier, providing a high level of security and preventing duplication or counterfeiting of the attached product.

The 1-Wire interface of the DS2411X#U allows for easy integration into designs, requiring only a single data line plus ground for communication. This simplifies the hardware design and reduces the overall system's footprint. The device can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply and further reducing component count and system complexity.

Applications for the DS2411X#U are diverse and include device authentication, secure data storage, and supply chain management. It's particularly useful in scenarios where a secure audit trail is necessary, such as in medical device tracking, warranty systems, or any situation where proof of product authenticity is required.

Maxim Integrated's commitment to quality ensures that the DS2411X#U is a reliable and durable choice for providing a unique identity to your electronic products. With its ease of integration, robust security features, and the backing of Maxim's reputation, the DS2411X#U is an excellent choice for designers looking to enhance their product's security and authenticity.
