16K bit Add–Only Memory
DS2505
020998 1/23
FEATURES
16384 bits Electrically Programmable Read Only
Memory (EPROM) communicates with the economy
of one signal plus ground
Unique, factory–lasered and tested 64–bit registra-
tion 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
TM
products
EPROM partitioned into sixty–four 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
Architecture allows software to patch data by super-
seding an old page in favor of a newly programmed
page
Reduces control, address, data, power, and program-
ming signals to a single data pin
Directly connects to a single port pin of a microproces-
sor and communicates at up to 16.3k bits per second
8–bit family code specifies DS2505 communications
requirements to reader
Presence detector acknowledges when the reader
first applies voltage

SILICON LABEL DESCRIPTION
The DS2505 16k bits Add–Only Memory identifies and
stores relevant information about the product to which it
is associated. This lot or product specific information
can be accessed with minimal interface, for example a
single port pin of a microcontroller. The DS2505 con-
sists of a factory–lasered registration number that
