DS1982U/DS1985U

UniqueWare™ iButton®

SPECIAL FEATURES

. 1024 bits or 16Kb Electrically Programmable

Read Only Memory (EPROM)

COMMON iButton FEATURES

. Multidrop controller for 1-Wire network

. 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

. 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

communicates with the economy of one

signal plus ground

. Unique, factory lasered and tested 64-bit

registration number (8-bit family code, 3-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

. 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

DESCRIPTION

UniqueWare iButtons are factory-programmed versions of the DS1982 (1024 bit) and the DS1985 (16Kb)

Add-Only iButtons, respectively. They differ from the regular devices in their custom ROM family codes

(see the Ordering Information) and the UniqueWare Identifier 5E7h in place of the upper 12 bits of the

standard serialization field. For technical details on the devices, refer to the DS1982 and DS1985 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 two pages of a device,

depending on the length of the customer-supplied data.

UniqueWare devices are only available to existing customers. New data patterns are no longer accepted.

The minimum order quantity (MOQ) is 34,000 pieces with higher quantities available in multiples of

17,000 pieces. UniqueWare iButtons can only be purchased in bulk form, delivered in bags. The shipment

quantity can be plus or minus 10% of the order quantity. Only the quantity shipped will be billed.

UniqueWare is a trademark of Maxim Integrated Products, Inc.
