Maxim Integrated DS1973-F3+ 4kb EEPROM iButton

The Maxim Integrated DS1973-F3+ is a highly reliable and secure 4kb EEPROM iButton that serves as a rugged data carrier in a variety of applications. This compact and durable device is part of the iButton family, which is designed to provide a portable, easy-to-use method for storing and transferring data. The DS1973-F3+ is encased in a sturdy stainless steel cover, providing a robust solution for data storage that can withstand harsh environments and rough handling.

The DS1973-F3+ offers 4096 bits of EEPROM memory, which is organized as sixteen pages of 256 bits each. The device features a unique, factory-lasered and tested 64-bit registration number which ensures absolute traceability. This registration number is used to address the iButton and can be used to protect the identity of the carrier, making it ideal for applications that require a high level of security.

One of the key features of the DS1973-F3+ is its ability to communicate with a host system via the 1-Wire protocol, a simple interface that requires only a single data line plus ground for communication. This enables the iButton to interface with a wide range of devices, including microcontrollers and computers. The 1-Wire protocol also allows for multiple DS1973-F3+ devices to reside on the same data line, enabling efficient integration into various systems and applications.

Applications for the DS1973-F3+ are diverse and include access control, asset tracking, work-in-progress tracking, and electronic cash transactions. Its rugged design makes it particularly suitable for use in environments where traditional card-based systems would fail, such as industrial sites, outdoor applications, and any setting where a small, portable, and durable data carrier is required.

The DS1973-F3+ operates over a wide voltage range of 2.8V to 6.0V and an extended temperature range, ensuring reliable performance under extreme conditions. With its combination of durability, security, and ease of integration, the Maxim Integrated DS1973-F3+ is a versatile choice for a broad spectrum of data storage and management solutions.
