PIN ASSIGNMENT

FEATURES

1024 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

TO-92

DATA

GND

8-PIN SO (150 MIL)

TSOC PACKAGE

Built-in multidrop controller ensures

compatibility with other MicroLAN products

EPROM partitioned into four 256-bit pages

for randomly accessing packetized data

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

reader first applies voltage

Low cost TO-92 or 8-pin SO, SOT-23 (3-

pin), TSOC and flip chip surface mount

package

See 56-G7010-001 for package outline.

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

and-reel are formed to approximately 100 mil

(2.54 mm) spacing. For details refer to drawing

56-G0006-003.

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
