Maxim Integrated DS2401AP Silicon Serial Number

The Maxim Integrated DS2401AP is a unique silicon serial number IC that provides a cost-effective method for embedding a non-alterable, factory-lasered, and absolutely unique 64-bit identification number (ID) into any electronic device. This tiny, robust serial number IC is an ideal solution for applications where simple, secure identification and authentication are essential.

The DS2401AP is housed in a compact TO-92 package, making it suitable for applications where space is at a premium. Its unique ID is composed of a 48-bit serial number, an 8-bit CRC for error checking, and an 8-bit Family Code (01h) that denotes the specific type of device. This combination ensures that no two chips will share the same number, providing an efficient means for tracking electronic components, managing inventory, enabling secure access, or embedding traceable identifiers in consumer products.

One of the key features of the DS2401AP is its compatibility with the 1-Wire interface. This single-contact serial interface allows seamless communication with a microcontroller or other host device with minimal wiring, which is particularly beneficial for systems where interconnect complexity and cost are concerns. The 1-Wire protocol also enables the DS2401AP to derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.

The device operates over a wide voltage range of 2.8V to 6.0V and is characterized for operation from -40°C to +85°C, ensuring reliable performance across diverse environments and applications. This makes the DS2401AP an excellent choice for use in industrial control systems, electronic accessories, warranty systems, or any application requiring a guaranteed unique electronic ID.

Integrating the DS2401AP into your design is straightforward, thanks to its simple interface and the support provided by Maxim Integrated. With its robust construction, unique identification capability, and ease of integration, the DS2401AP stands out as a practical component for enhancing the security and traceability of your electronic systems.
