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

. Built-in

multidrop

controller

ensures

compatibility with other 1-Wire Net

products

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

. 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

NOTE: The leads of TO-92 packages on tape-

and-reel are formed to approximately 100 mil

(2.54 mm) spacing. For details see the Package

Information section.

ORDERING INFORMATION

. 8-bit family code specifies DS2505

communications requirements to reader

. Presence detector acknowledges when the

reader first applies voltage

. Low cost TO-92 or 6-pin TSOC surface

mount package

. Reads over a wide voltage range of 2.8V to

6.0V from -40°C to +85°C; programs at

11.5V to 12.0V from -40°C to +50°C
