FEATURES
256-bit Electrically Erasable Programmable
Read Only Memory (EEPROM) plus 64-bit
one-time programmable application register
Unique, factory-lasered and tested 64-bit
registration 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 products
EEPROM organized as one page of 32 bytes
for random access
Reduces control, address, data, and power to a
single data pin
Directly connects to a single port pin of a
microprocessor and communicates at up to
15.3kbits 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 and UCSP
surface mount package
Reads and writes over a wide voltage range of
2.8V to 5.25V from -40°C to +85°C

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 consists 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 programmable 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 1-Wire protocol, which requires only a single data lead and a ground return.
The 48-bit serial number that is factory-lasered into each DS2430A provides a guaranteed unique identity
that allows for absolute traceability. The TO-92 and TSOC packages provide a compact enclosure that
allows standard assembly equipment to handle the device easily for attachment to printed circuit boards
or wiring. Typical applications include storage of calibration constants, board identification, and product
revision status.
