The DS2431 is a 1024-bit, 1-Wire

nized as four memory pages of 256 bits each. Data is

written to an 8-byte scratchpad, verified, and then

copied to the EEPROM memory. As a special feature, the

four memory pages can individually be write protected or

put in EPROM-emulation mode, where bits can only be

changed from a 1 to a 0 state. The DS2431 communi-

cates over the single-conductor 1-Wire bus. The commu-

nication follows the standard 1-Wire protocol. Each

device has its own unalterable and unique 64-bit ROM

registration number that is factory lasered into the chip.

The registration number is used to address the device in

a multidrop, 1-Wire net environment.
