SPECIAL FEATURES

COMMON iButton FEATURES

. Unique, factory-lasered and tested 64-bit

registration number (8-bit family code + 48-bit

serial number + 8-bit CRC tester) assures

absolute traceability because no two parts are

alike

. 1024 bits Electrically Programmable Read-

Only Memory (EPROM) communicates with

the economy of one signal plus ground

. EPROM partitioned into four 256-bit pages for

randomly accessing packetized data

. Each memory page can be permanently write-

protected to prevent tampering

. Multidrop controller for MicroLAN

. Digital identification and information by

momentary contact

. Chip-based data carrier compactly stores

information

. Data can be accessed while affixed to object

. Economically communicates to bus master

with a single digital signal at 16.3kbps

. Standard 16mm diameter and 1-Wire^®protocol

ensure compatibility with iButton^®family

. Button shape is self-aligning with cup-shaped

probes

. Durable stainless steel case engraved with

registration number withstands harsh

environments

. Device is an “add only” memory where

additional data can be programmed into

EPROM without disturbing existing data

. Architecture allows software to patch data by

superseding an old page in favor of a newly

programmed page

. Reduces control, address, data, power, and

programming signals to a single data pin

. 8-bit family code specifies DS1982

communications requirements to reader

. Reads over a wide voltage range of 2.8V to

6.0V from -40°C to +85°C; programs at 11.5V

to 12.0V from -40°C to +50°C

. Easily affixed with self-stick adhesive backing,

latched by its flange, or locked with a ring

pressed onto its rim

. Presence detector acknowledges when reader

first applies voltage
