DS1973 4Kb EEPROM iButton®

The DS1973 4Kb EEPROM iButton™ 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, for example a single port pin of a micro-controller. The DS1973 consists of a factory-lasered registration number that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (23H) plus 4096 bits of EEPROM. The power to program and read the DS1973 is derived entirely from the 1-Wire communication line. The memory is organized as sixteen pages of 256 bits each. The 64-bit registration number provides a guaranteed unique identity, which allows for absolute traceability. Data is transferred serially via the 1-Wire™ protocol which requires only a single data lead and a ground return. The durable MicroCan package is highly resistant to harsh environments such as dirt, moisture, and shock. Its compact button-shaped profile is self-aligning with cup-shaped receptacles, allowing the DS1973 to be used easily by human operators or automatic equipment.
