1024-Bit, 1-Wire EEPROM Evaluation Kit Available Design Resources Support Click here to ask an associate for production status of specific part numbers. DS28E07 General Description The DS28E07 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 user 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. Each device has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip. The communication follows the 1-Wire protocol with the ROM ID acting as node address in the case of a multiple-device 1-Wire network. Applications ● Accessory/PCB Identification ● Medical Sensor Calibration Data Storage ● Analog Sensor Calibration Including IEEE P1451.4 Smart Sensors ● Ink and Toner Print Cartridge Identification ● After-Market Management of Consumables Benefits and Features ● Partitioning of Memory Provides Greater Flexibility in Programming User Data 1024 Bits of EEPROM Memory Organized as Four Pages of 256 Bits Individual Memory Pages Can Be Permanently Write Protected or Put in EPROM-Emulation Mode (Write to 0) ● Advanced 1-Wire Protocol Minimizes Interface to Just Single IO Reducing Required Pin Count and Enhancing Reliability Unique Factory-Programmed, Unalterable 64-Bit Identification Numb...
