DS2431 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 singleconductor 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.
