The DS1971-F5 iButton from Maxim Integrated is a robust, self-contained system that carries global unique ID and user-programmable memory. This powerful microchip encapsulated in a durable stainless-steel can is designed to be easily attached to items that need to be identified and tracked. The DS1971-F5 is part of the iButton family, which provides a portable, durable and touch-and-go identification solution.

Key Features

• Memory: The device features a 256-bit Electrically Erasable Programmable Read-Only Memory (EEPROM) partitioned into 64-bit pages. This allows for the storage of vital data that can be written and read over a wide voltage range of 2.8V to 6.0V.
• Data Security: The memory is protected by a secure architecture that includes a factory lasered and tested 64-bit registration number to ensure a unique identity. Additionally, an 8-byte write-only secret and a read/write password protect the memory from unauthorized access.
• Durability: Encased in a rugged stainless-steel cover, the iButton is resistant to harsh environments and can withstand a wide temperature range, making it suitable for a variety of industrial and outdoor applications.
• Communication: Data is transferred serially through the 1-Wire protocol, which requires only a single data lead and a ground return. This simplifies system design and lowers the costs of ancillary components.
• Multi-purpose: The DS1971-F5 can be used for a wide array of applications, including access control, inventory management, time and attendance tracking, and more.
• Easy Integration: The device can be mounted on almost any object, including containers, pallets, or bags, with the use of an iButton fob.
