EEPROM
DS2430A
020998 1/16
FEATURES
256–bit Electrically Erasable Programmable Read
Only Memory (EEPROM) plus 64–bit one–time pro-
grammable application register
Unique, factory–lasered and tested 64–bit registra-
tion number (8–bit family code + 48–bit serial number
+ 8–bit CRC tester) assures absolute identity
because no two parts are alike
Built–in multidrop controller ensures compatibility
with other MicroLAN
TM
products
EEPROM organized as one page of 32 bytes for ran-
dom access
Reduces control, address, data and power 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 DS2430A communication
requirements to reader
Presence detector acknowledges when reader first
applies voltage
Low cost TO–92 or 6–pin TSOC surface mount pack-
age
Reads and writes over a wide voltage range of 2.8V
to 6.0V from –40
°
C to +85

SILICON LABEL DESCRIPTION
The DS2430A 256–bit 1–Wire EEPROM 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 DS2430A con-
sists of a factory–lasered registration number that
includes a unique 48–bit serial number, an 8–bit CRC,
and an 8–bit Family Code (14h) plus 256 bits of user–
programmable EEPROM and a 64–bit one–time pro-
grammable application register. The power to read and
write the DS2430A is derived entirely from the 1–Wire
communication line. Data is transferred serially via the
