SPECIAL FEATURES
1024 bits, 16K bits or 64K bits Electrically Program-
mable 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, 36–bit serialization, 12–bit
UniqueWare Identifier 5E7H, 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 256–bit pages for randomly
accessing packetized data records
Each memory page can be permanently write–pro-
tected to prevent tampering
Device is an “add only” memory where additional data
can be programmed into EPROM without disturbing
existing data
Reduces control, address, data, power and program-
ming signals to a single pin
Directly connects to a single port pin of a microproces-
sor and communicates at up to 16.3k bits per second
Presence detector acknowledges when reader first
applies voltage
Low cost TO–92/PR–35 or 8–pin SOIC and TSOC sur-
face mount packages
Reads over a wide voltage range of 2.8V to 6.0V from

SILICON LABEL DESCRIPTION
UniqueWare Add–Only Memories are factory pro-
grammed versions of the DS2502 (1024 bit), the
DS2505 (16K bit) and the DS2506 (64K bit) Add–Only
Memories, respectively. They differ from the regular
devices in their custom ROM family codes (see Order-
ing Information) and the UniqueWare Identifier 5E7 in
place of the upper 12 bits of the standard serialization
field. For technical details on the devices please refer to
the DS2502, DS2505 and DS2506 data sheets.
UniqueWare Add–Only Memories are only available
preprogrammed with customer–specific and write–pro-
tected data. UniqueWare data fills at least one but no
more than the first four pages of a device, depending on
the length of the customer–supplied data. This leaves
up to three (DS2502–UNW), 63 (DS2505–UNW) or 255
(DS2506–UNW) memory pages available for program-
ming in the application.
For more details on UniqueWare and how to set up data
files, please refer to the UniqueWare Project Setup
Manual, available as Application Note 99 from Dallas
Semiconductor. The UniqueWare Project Setup Soft-
ware is availble from the Dallas Semiconductor FTP
Site at
ftp://ftp.dalsemi.com/pub/auto_id, unwsetup.exe.
