DS1996L-F5 / DS1996L-F5+ - 64 kbit Memory iButton by Dallas Semiconductor

Product Code: DS1996L-F5 Price: Check Latest 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. Key Features 65,536 bits read/write nonvolatile memory Communication speed of 142kbits/second in overdrive mode 1-Wire interface 64-bit ROM registration number 256-bit scratchpad Data integrity assured with strict read/write protocols Memory partitioned into 256 256-bit pages Operating range -40°C to +70°C >10 years data retention Key Specifications: iButton Products Part Number Memory Type Memory Size Package DS1996 NV RAM 64K bits F5 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
