 DS1996L-F5 has been discontinued and replaced with a RoHS compliant drop-in replacement, DS1996L-F5+.
The DS1996 iButton is a portable data carrier that can store up to
64kbits in nonvolatile memory. It communicates with a processor using the 1-Wire
protocol through a hardware port interface. The port interface provides both the
physical link and handles the communication protocols that enable the processor
to access iButton resources with simple commands. Other memory includes a
unique, 64-bit registration number and a 256-bit scratchpad from which data can
be verified before copying to memory. An overdrive mode boosts communication speed
to 142kbits/second.
The DS1996 is extremely durable and can be attached to an object, person, or
circuit board by means of accessories. Applications include access control, work-in-progress
tracking, storage of calibration constants, and debit tokens.

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 by momentary contact.
- Chip-based data carrier compactly stores information.
- Data can be accessed while affixed to an 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 cupshaped 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 1, Division 1, Group A, B, C and D locations
