The Maxim Integrated DS2401+T&R is a compact, easy-to-integrate silicon serial number IC that provides a unique identity to hardware components. This tiny chip, often referred to as the "Silicon Serial Number," is an essential part of any system where secure identification and authenticity verification are critical. It is widely used in applications such as network hardware, medical devices, and other electronic equipment where individual device identification is necessary for security and inventory purposes.

The DS2401+T&R is based on Maxim's proprietary 1-Wire® protocol, which allows communication through a single data line plus ground for simplified connectivity. This feature enables the serial number to be read with minimal wiring, which is particularly advantageous in systems where space is at a premium or complex wiring is impractical.

Each DS2401+T&R is factory-lasered with a unique 64-bit registration number that includes a 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (01h). This unique number is unalterable and provides a guaranteed unique identity that can be securely queried and verified at any time.

The chip's small footprint is delivered in a TO-92 package, making it suitable for PCB mounting or embedding within a cable or connector assembly. The "T&R" designation indicates that the product is provided in tape and reel packaging, which facilitates automatic placement and volume manufacturing processes.

The DS2401+T&R operates over a wide voltage range of 2.8V to 6.0V and a broad temperature range, making it versatile for various environments and applications. Its low-cost, small size, and ease of integration make it an excellent choice for anti-counterfeiting, access control, and supply chain integrity.

Maxim Integrated's commitment to quality and reliability ensures that the DS2401+T&R provides a dependable solution for secure electronic identification. With its unique combination of simplicity, security, and scalability, the DS2401+T&R is an invaluable component for any system requiring definitive hardware identification.
