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

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

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
