Detailed Description
The DS2431 combines 1024 bits of EEPROM, an
8-byte register/control page with up to 7 user read/write
bytes, and a fully featured 1-Wire interface in a single
chip. Each DS2431 has its own 64-bit ROM registration
number that is factory lasered into the chip to provide a
guaranteed unique identity for absolute traceability.
Data is transferred serially through the
PARASITE POWER
1-Wire protocol, which requires only a single data lead
and a ground return. The DS2431 has an additional

memory area called the scratchpad that acts as a
buffer when writing to the main memory or the register
page. Data is first written to the scratchpad from which
it can be read back. After the data has been verified, a
Copy Scratchpad command transfers the data to its
final memory location. The DS2431 applications include
accessory/PCB identification, medical sensor calibra-
tion data storage, analog sensor calibration including
IEEE P1451.4 smart sensors, ink and toner print car-

Overview
The block diagram in Figure 1 shows the relationships
between the major control and memory sections of the
DS2431. The DS2431 has four main data components:
64-bit lasered ROM, 64-bit scratchpad, four 32-byte
