Product Description
DS2431P Memory IC Chip 1024-Bit 1-Wire EEPROM Memory IC TSOC-6 Package
The DS2431P 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 DS2431P communicates over the single-conductor 1-Wire bus following the standard 1-Wire protocol. Each device has its own unalterable and unique 64-bit ROM registration number that is factory lasered into the chip.
