FEATURES

PIN ASSIGNMENT

ꢀ 65536 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

DATA

GND

8-PIN SOIC

(208 mil)

ꢀ Built-in multidrop controller ensures

compatibility with other MicroLAN products

ꢀ EPROM partitioned into two hundred fifty six

256-bit pages for randomly accessing

packetized data records

ꢀ 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

8-Pin SOIC Package

ꢀ Overdrive mode boosts communication speed

to 142 kbits per second

ꢀ 8-bit family code specifies DS2506

communications requirements to reader

ꢀ Presence detector acknowledges when the

reader first applies voltage

ꢀ Low cost PR35 or 8-pin SOIC 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
