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
? 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
Functional Diagrams
16.3 kbits per second
? 8-bit family code specifies DS2502
communications requirements to reader
? Presence detector acknowledges when the
reader first applies voltage
? Low cost TO-92, SFN, or 8-pin SO, SOT-23
(3-pin), TSOC and flip chip 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
