DS2431P+

The DS2431P+ is a 1024bit, 1-Wire EEPROM in 6 pin TSOC package. This EEPROM chip is organized as four memory pages of 256 bits each. Data is written to an 8byte scratchpad, verified and then copied to EEPROM memory. The four memory pages can individually be write protected or put in EPROM emulation mode where bits can only be changed from 1 to 0 state. The DS2431 communicates over single conductor 1-Wire bus. The communication follows the standard 1-Wire protocol. Each device has its own unalterable and unique 64bit ROM registration number that is factory lasered into chip. The registration number is used to address device in a multidrop, 1-wire net environment.
