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
142k bits per second
EPROM partitioned into two hundred and fifty–six
256–bit pages for randomly accessing packetized
data records
Each memory page can be permanently write–pro-
tected 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 super-
seding an old page in favor of a newly programmed
page
Reduces control, address, data, power, and program-
ming 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

COMMON iButton FEATURES
Unique, factory–lasered and tested 64–bit registra-
tion 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
TM
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 16.3k bits per second
Standard 16 mm diameter and 1–Wire
TM
protocol
ensure compatibility with iButton family
Button shape is self–aligning with cup–shaped
probes
Durable stainless steel case engraved with registra-
tion 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 Appara-
tus, Approved under Entity Concept for use in Class
I, Division 1, Group A, B, C and D Locations (applica-
tion pending)
