DS1971-F5+

DS1971-F5+ is a 256-bit EEPROM iButton. It is a rugged read/write data carrier that identifies and stores relevant information about the product or person to which it is attached. The power to program and read the DS1971 is derived entirely from the 1-wire communication line. Data is transferred serially via the 1-wire protocol which requires only a single data lead and a ground return. The 48-bit serial number that is factory-lasered into each DS1971 provides a guaranteed unique identity which allows for absolute traceability. Its compact button-shaped profile is self-aligning with cup-shaped receptacles, allowing the DS1971 to be used easily by human operators or automatic equipment. Accessories permit the DS1971 to be mounted on printed circuit boards, plastic key fobs, photo-ID badges, ID bracelets, and many other objects. Applications include work-in-progress tracking, electronic travellers, access control and storage of calibration constants.
