4-kbit EEPROM iButton^TM

www.iButton.com

SPECIAL FEATURES

ꢀ Chip-based data carrier compactly stores

information

ꢀ 4096 bits Electrically Erasable

Programmable Read Only Memory

(EEPROM)

ꢀ Data can be accessed while affixed to object

ꢀ Economically communicates to bus master

with a single digital signal at 16.3 kbits per

second

ꢀ Overdrive mode boosts communication

speed to 142 kbits per second

ꢀ 256–bit scratchpad ensures integrity of data

transfer

ꢀ Memory partitioned into 256–bit pages for

packetizing data

ꢀ Reduces control, address, data and power to

a single data pin

ꢀ 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

ꢀ 8–bit family code specifies DS1973

communication requirements to reader

ꢀ Reads and writes over a wide voltage range

of 2.8V to 6.0V from –40°C to +85°C

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 identity because no two

parts are alike

ꢀ Multidrop controller for MicroLAN

ꢀ Digital identification and information by

momentary contact

ꢀ Presence detector acknowledges when reader

first applies voltage

ꢀ Meets UL#913 (4^thEdit.); Intrinsically Safe

Apparatus, Approved under Entity Concept

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

and D Locations (application pending)
