SPECIAL FEATURES
§ 4096 bits of read/write nonvolatile memory
(DS1993 and DS1994)
§ 1024 bits of read/write nonvolatile memory
(DS1992)
§ 256-bit scratchpad ensures integrity of data
transfer
§ Memory partitioned into 256-bit pages for
packetizing data
§ Data integrity assured with strict read/write
protocols
§ Contains real time clock/calendar in binary
format (DS1994)
§ Interval timer can automatically accumulate
time when power is applied (DS1994)
§ Programmable cycle counter can accumulate
the number of system power-on/off cycles
(DS1994)
§ Programmable alarms can be set to generate
interrupts for interval timer, real time clock,
and/or cycle counter (DS1994)
§ Write protect feature provides tamper-proof
time data (DS1994)
§ Programmable expiration date that will limit
access to SRAM and timekeeping (DS1994)
§ Clock accuracy is better than ±2 minute/
month at 25°C (DS1994)
§ Operating temperature range from -40°C to
+70°C
§ Over 10 years of data retention
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
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
