SPECIAL FEATURES
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
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
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 –4
0°
C to +8
5°
C
COMMON iButton FEATURES
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 16.3k bits per second
Standard 16 mm 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
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
Apparatus, Approved under Entity Concept
for use in Class I, Division 1, Group A, B, C
and D Locations (application 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 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”.
