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

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

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

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
