General Description of DS1990 iButton
The DS1990A serial number iButton® is a rugged data carrier that serves as an electronic registration number for automatic
identification. Data is transferred serially through the 1-Wire® protocol, which requires only a single data lead and a ground
return. Every DS1990A is factory lasered with a guaranteed unique 64-bit registration number that allows for absolute
traceability. The durable stainless-steel iButton package is highly resistant to environmental hazards such as dirt, moisture, and
shock. Its compact coin-shaped profile is selfaligning with mating receptacles, allowing the DS1990A to be used easily by human
operators. Accessories enable the DS1990A iButton to be mounted on almost any object, including containers, pallets, and bags.
