SPECIAL FEATURES
§ 65536 bits Electrically Programmable Read
Only Memory (EPROM) communicates with
the economy of one signal plus ground
§ Overdrive mode boosts communication
speed to 142 kbits per second
§ EPROM partitioned into two hundred and 56
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
§ Architecture allows software to patch data by
superseding an old page in favor of a newly
programmed page
§ Reduces control, address, data, power, and
programming signals to a single data pin
§ 8-bit family code specifies DS1986
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
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
§ 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 (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)
