DS2431 - 1024-Bit, 1-Wire EEPROM
The DS2431 is a 1024-bit, 1-Wire® EEPROM chip orga-nized 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 ...
