General Description
The DS2431-A1 is an AEC-Q100 Grade 1 qualified ver-
sion of the DS2431. The logical behavior of both ver-
sions is identical. The DS2431-A1 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, veri-
fied, 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-A1 communicates over the single-conduc-
tor 1-Wire bus. The communication follows the standard
1-Wire protocol. Each device has its own unalterable
and unique 64-bit ROM registration number that is fac-
tory lasered into the chip. The registration number is
used to address the device in a multidrop 1-Wire net
environment.
