GENERAL DESCRIPTION
The DS2431 is a 1024-bit, 1-Wire
EEPROM chip
organized 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 communicates over the single-
conductor 1-Wire bus. The communication follows
the standard Dallas Semiconductor 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.
