FEATURES

PIN ASSIGNMENT

ꢀ 16384 bits Electrically Programmable Read

Only Memory (EPROM) communicates with

the economy of one signal plus ground

ꢀ 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

3.7 X 4.0 X 1.5 mm

ꢀ Built-in

multidrop

controller

ensures

Net

compatibility with other 1-Wire

products

Side View

See Mech.

ꢀ EPROM partitioned into sixty-four 256-bit

pages for randomly accessing packetized data

records

Drawing Section

ꢀ Each memory page can be permanently write-

protected to prevent tampering

ꢀ Device is an “add only” memory where

additional data can be programmed into

EPROM without disturbing existing data

ꢀ Architecture allows software to patch data by

superseding an old page in favor of a newly

programmed page

Drawings Section

ꢀ Reduces control, address, data, power, and

programming signals to a single data pin

ꢀ Directly connects to a single port pin of a

microprocessor and communicates at up to

16.3 kbits per second
