Maxim Integrated DS2404S - Silicon Serial Number

The DS2404S from Maxim Integrated is a unique device that provides a robust solution for electronic identification. This compact component is part of Maxim's family of silicon serial numbers designed to offer a non-volatile memory with a factory-lasered and tested 64-bit registration number that ensures absolute traceability. Because no two parts are alike, this registration number is guaranteed to be unique for each DS2404S, making it ideal for anti-counterfeiting, asset tracking, and electronic device identification applications.

The DS2404S incorporates a multitude of features that make it versatile and easy to use in a variety of systems. It includes an embedded 1-Wire interface which allows for simple and cost-effective communication with the host controller. This interface requires only a single data line and a ground return, minimizing the complexity and the cost of the system interface.

Additionally, the DS2404S offers an integrated real-time clock (RTC) and timer that is backed by an on-chip oscillator. This RTC provides a full timestamp for each transaction, which is critical for data logging and monitoring applications. The timekeeping is maintained as long as the device is powered by its supply voltage, and it can be battery-backed to ensure continuous operation during power-down situations.

For data security and integrity, the DS2404S includes a write-cycle counter for each memory page, providing a means for write-protecting the memory to prevent unauthorized data modification. The device also supports a programmable interrupt output and a programmable alarm output which can be used to implement custom alarm functions or to signal the host microcontroller of specific events.

Constructed with Maxim Integrated's renowned quality, the DS2404S is available in a surface-mount package, making it suitable for automated assembly processes and space-constrained applications. This device is a perfect choice for designers looking for a reliable and secure way to incorporate electronic identification into their products.

Whether it's for warranty systems, secure access, or product authentication, the DS2404S stands out as a trusted solution for adding a unique and secure identity to electronic devices.
