The DS1971-F5+ is a 256bit EEPROM iButton in F5 MicroCan package. This is a rugged read/write data carrier that identifies and stores relevant information about the product or person to which it is attached. This information can be accessed with minimal hardware. The DS1971 consists of a factory-lasered registration number that includes a unique 48bit serial number, an 8bit CRC and an 8bit family code (14H) plus 256bits of EEPROM. 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 48bit serial number that is factory lasered into each DS1971 provides a 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.
