SPECIAL FEATURES

COMMON iButton FEATURES

ꢀ Multidrop controller for MicroLAN

ꢀ Digital identification and information by

momentary contact

ꢀ Chip–based data carrier compactly stores

information

ꢀ 1024 bits, 16K bits or 64K bits Electrically

Programmable Read Only Memory

(EPROM) communicates with the economy

of one signal plus ground

ꢀ

Unique, factory lasered and tested 64–bit

registration number (8–bit family code, 36–bit

serialization, 12–bit UniqueWare Identifier

5E7H, 8–bit CRC tester) assures absolute

traceability because no two parts are alike

ꢀ Data can be accessed while affixed to object

ꢀ

Economically communicates to bus master with

a single digital signal at 16.3k bits per second

Standard 16 mm diameter and 1–Wire protocol

ensure compatibility with iButton family

ꢀ

ꢀ EPROM partitioned into 256–bit pages for

randomly accessing packetized data records

ꢀ Each memory page can be permanently

write–protected to prevent tampering

ꢀ Device is an “add only” memory where

additional data can be programmed into

EPROM without disturbing existing data

ꢀ Reduces control, address, data, power and

programming signals to a single pin

ꢀ Button Shape is self–aligning with cup–

shaped probes

ꢀ Durable stainless steel case engraved with

registration number withstands harsh

environments

ꢀ Easily affixed with self–stick adhesive

backing, latched by its flange, or locked with

a ring pressed onto its rim

ꢀ 8–bit family code specifies device

communications requirements to reader

ꢀ Presence detector acknowledges when reader

first applies voltage

ꢀ Presence detector acknowledges when reader

first applies voltage

ꢀ Meets UL#913 (4th edit.); Intrinsically Safe

Apparatus, Approved under Entity Concept

for use in Class I, Division 1, Group A, B, C

and D Locations (application pending)

ꢀ Reads over a wide voltage range of 2.8V to

6.0V from –40°C to +85°C

iButton DESCRIPTION

UniqueWare iButtons are factory programmed versions of the DS1982 (1024 bit), the DS1985 (16K bit)

and the DS1986 (64K bit) Add–Only iButtons, respectively. They differ from the regular devices in their

custom ROM family codes (see Ordering Information) and the UniqueWare Identifier 5E7 in place of the

upper 12 bits of the standard serialization field. For technical details on the devices please refer to the

DS1982, DS1985 and DS1986 data sheets.

UniqueWare Add–Only iButtons are only available preprogrammed with customer–specific and write–

protected data. UniqueWare data fills at least one but no more than the first four pages of a device,

depending on the length of the customer–supplied data. This leaves up to three (DS1982U), 63

(DS1985U) or 255 (DS1986U) memory pages available for programming in the application.

For more details on UniqueWare and how to set up data files, please refer to the UniqueWare Project

Setup Manual, available as Application Note 99 from Dallas Semiconductor. The UniqueWare Project

Setup Software is available from the Dallas Semiconductor FTP Site at

ftp://ftp.dalsemi.com/pub/auto_id, file name “unwsetup.exe”.
