DS1971
256-Bit EEPROM iButton™
SPECIAL FEATURES
§ 256-bit Electrically Erasable Programmable
Read Only Memory (EEPROM)
communicates with the economy of one
signal plus ground
§ EEPROM organized as one 256-bit page
§ 64-bit one-time programmable application
register is automatically write-protected after
programming
§ Reduces control, address, data, power, and
programming signals to a single data pin
§ 8-bit family code specifies DS1971
communications 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, 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 (application pending)
