DS2431

1024-Bit 1-Wire EEPROM

GENERAL DESCRIPTION

FEATURES

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.

1024 Bits of EEPROM Memory Partitioned into

Four Pages of 256 Bits
