DS1985

16Kb Add-Only iButton

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

. Multidrop controller for MicroLAN

. Digital identification and information by

momentary contact

16384 bits Electrically Programmable Read Only

Memory (EPROM) communicates with the

economy of one signal plus ground

EPROM partitioned into 64 256-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

. Chip-based data carrier compactly stores

information

Architecture allows software to patch data by

superseding an old page in favor of a newly

programmed page

. 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

Reduces control, address, data, power, and

programming signals to a single data pin

8-bit family code specifies DS1985

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 +85°C

F3 MicroCan

. 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
