1024 bits Electrically Programmable Read-
Only Memory (EPROM) communicates with
the economy of one signal plus ground
EPROM partitioned into four 256-bit pages for
randomly accessing packetized data
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 DS1982
communications requirements to reader
Reads over a wide voltage range of 2.8V to

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 16.3kbps
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
6.0V from -40°C to +85°C; programs at 11.5V
to 12.0V from -40°C to +50°C
