Maxim Integrated DS2401+ Silicon Serial Number

The DS2401+ Silicon Serial Number is a compact, easy-to-integrate device from Maxim Integrated that provides a unique identity to hardware components. This device is a part of the company's renowned family of 1-Wire® devices, which are known for their ability to communicate through a single data line (plus ground) with minimal interface requirements.

The DS2401+ is often used for authentication and device identification purposes. It contains a factory-lasered, 64-bit ROM that includes a unique 48-bit serial number, an 8-bit CRC for verification, and an 8-bit Family Code (01h). This unique serial number is a permanent identifier that provides a robust and foolproof way to ensure the authenticity of a component or device, making it an essential part of anti-counterfeiting measures in supply chains.

Due to its small size and low power consumption, the DS2401+ is particularly suitable for portable or compact electronic devices. It operates over a wide voltage range of 2.8V to 6.0V and is functional across a broad temperature range, making it versatile for various applications. The device is also designed to be easily integrated into systems with its TO-92, SOT-223, and TSOC packages available to fit different design requirements.

The communication with the DS2401+ is achieved through the 1-Wire protocol, which requires only a single data line and a ground return, thus simplifying the physical design and reducing the overall cost of the system. This protocol enables the device to be connected in a multidrop configuration, allowing multiple DS2401+ devices to coexist on the same data line. This feature is particularly useful for applications where multiple devices need to be individually addressed and accessed via a common communication bus.

Overall, the Maxim Integrated DS2401+ Silicon Serial Number is a reliable and secure solution for providing a unique identity to electronic devices. Its robust construction, coupled with the simplicity of the 1-Wire interface, makes it an ideal choice for manufacturers looking to protect their products from counterfeiting and ensure traceability throughout their product's lifecycle.
