iButton DESCRIPTION

SPECIAL FEATURES

The DS1977 is a 32KB 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

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 iButton to be mounted on almost any

object, including containers, pallets, and bags.

32KB EEPROM Organized as Pages of 64 Bytes

Each

Optional Password Protection with Different 64-

Bit Passwords for Read and Full Access

Communicates to Host with a Single Digital

Signal at Up to 15.3kbps at Standard Speed or

Up to 125kbps in Overdrive Mode Using 1-Wire

Protocol

Operating Range: 2.8V to 5.25V, -40C to +85C

Minimum 100k Write Cycles Endurance

15kV Built-in ESD Protection
