SPECIAL FEATURES
4096 bits Electrically Erasable
Programmable Read Only Memory
(EEPROM)
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
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
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 16.3 kbits 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 (4
th
Edit.); Intrinsically Safe
Apparatus, Approved under Entity Concept
for use in Class I, Division 1, Group A, B, C
and D Locations (application pending)
