16384 bits Electrically Programmable Read Only
Memory (EPROM) communicates with the
economy of one signal plus ground
EPROM partitioned into 64 256-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 DS1985
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

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
F3 MicroCan
?
?
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
