SPECIAL FEATURES
§
Digital thermometer measures temperatures
from -55°C to +100°C in typically 0.2
seconds
§
Zero standby power
§
0.5°C resolution, digital temperature reading
is two’s complement of °C value
§
Access to internal counters allows increased
resolution through interpolation
§
Reduces control, address, data, and power to
a single data contact
§
8-bit device-generated CRC for data integrity
§
8-bit family code specifies DS1920
communications requirements to reader
§
Special command set allows user to skip
ROM section and do temperature
measurements simultaneously for all devices
on the bus
§
2 bytes of EEPROM to be used either as
alarm triggers or user memory
§
Alarm search directly indicates which device
senses alarming temperatures
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 16.3k 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
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)
