Description
General part information
DS1977 Series
The iButton®32KB EEPROM (DS1977) provides password protected access to data, both for read-only and full access. Data is transferred serially through the 1-Wire®protocol, which requires only a single data lead and a ground return. Every DS1977 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. Accessories permit the DS1977 to be mounted on almost any object, including containers, pallets, and bags.ApplicationsAudit Data Storage and CarrierHealth Data CarrierMaintenance/Inspection Data StorageMedical Data Carrier
