SPECIAL FEATURES
1024 bits, 16K bits or 64K bits Electrically Program-
mable 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) as-
sures absolute traceability because no two parts are
alike.
EPROM partitioned into 256–bit pages for randomly
accessing packetized data records
Each memory page can be permanently write–pro-
tected 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 program-
ming signals to a single pin
8–bit family code specifies device communications
requirements to reader
Presence detector acknowledges when reader first
applies voltage
Reads over a wide voltage range of 2.8V to 6.0V from
–40
°
C to +85
°

COMMON iButton FEATURES
Multidrop controller for MicroLAN
Digital identification and information by momentary
contact
Chip–based data carrier compactly stores informa-
tion
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 en-
sure compatibility with iButton family
Button Shape is self–aligning with cup–shaped
probes
Durable stainless steel case engraved with registra-
tion number withstands harsh environments
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
Meets UL#913 (4th edit.); Intrinsically Safe Appara-
tus, Approved under Entity Concept for use in Class
I, Division 1, Group A, B, C and D Locations (applica-
tion pending)
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 pre-
programmed with customer–specific and write–pro-
tected 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 Soft-
ware is available from the Dallas Semiconductor FTP
Site at
ftp://ftp.dalsemi.com/pub/auto_id, unwsetup.exe.
