General Description

The DS1977 is a 32Kbyte EEPROM in a rugged,

iButton enclosure. Access to the memory can be

password-protected with different passwords for read-

only and full access. Data is transferred serially via

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 trace-ability. The

durable stainless steel iButton package is highly

resistant to environmental hazards such as dirt and

shock. Accessories permit the DS1977 iButton to be

mounted on almost any object, including containers,

pallets and bags.
