DS2431-A1 Datasheet | Maxim Integrated

Rev 1; 3/08 1024-Bit, 1-Wire EEPROM for Automotive Applications General Description The DS2431-A1 is an AEC-Q100 Grade 1 qualified version of the DS2431. The logical behavior of both versions is identical. The DS2431-A1 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-A1 municates over the single-conductor 1-Wire bus. The munication follows the standard 1-Wire protocol. Each...
