 65536 bits Electrically Programmable Read
Only Memory (EPROM) communicates with
the economy of one signal plus ground
 Overdrive mode boosts communication
speed to 142 kbits per second
 EPROM partitioned into two hundred and 56
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
 8-bit family code specifies DS1986
communications requirements to reader
 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 +85°C
 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
