1024-Bit 1-Wire EEPROM

Maxim 1024-Bit, 1-Wire EEPROM Chip. This memory chip comes organised as four memory pages of 256bits each. The four memory pages can individually be write-protected or put in EEPROM emulation mode, where bits can only be changed from a 1-0 state. Data is written to an 8byte scratchpad is verified and then copied to EEPROM memory. Each device has its own unalterable and unique 64-bit ROM registration number that is factory lasered into the chip.

Features and Benefits

- Easily Add Traceability and Relevant Information to Any Individual System
- 1024 Bits of EEPROM Memory Partitioned Into Four Pages of 256 Bits
- Individual memory pages are able to be write-protected or put in EEPROM emulation mode
- Minimalist 1-Wire Interface Lowers Cost and Interface Complexity
- Reads and Writes Over a Wide Voltage Range from 2.8V to 5.25V from -40°C to +85°C
- Communicates to Host with a Single Digital Signal at 15.4kbps or 125kbp
- Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise
- Temperature Range -40°C - +85°C

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
