TM
DS1973
PRELIMINARY
062498 1/2
SPECIAL FEATURES
4096 bits Electrically Erasable Programmable Read
Only Memory (EEPROM)
Overdrive mode boosts communication speed to
142k bits 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, factorylasered and tested 64bit registration
number (8bit family code + 48bit serial number + 8bit
CRC tester) assures absolute identity because no two
parts are alike
Multidrop controller for MicroLAN
TM
Digital identification and information by momentary
contact
Chip–based data carrier compactly stores informa-
tion
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)
