DS2431
1024-Bit, 1-Wire EEPROM
General Description
The DS2431 is a 1024-bit, 1-Wire ? EEPROM chip orga-
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.
