DS2431  
1024-Bit, 1-Wire EEPROM  
General Description  
Benefits and Features  
● Easily Add Traceability and Relevant Information to  
®
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 state. The DS2431 communi-  
cates over the single-conductor 1-Wire bus. The com-  
munication follows 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.  
The registration number is used to address the device in  
a multidrop, 1-Wire net environment.  
Any Individual System  
• 1024 Bits of EEPROM Memory Partitioned Into  
Four Pages of 256 Bits  
• Individual Memory Pages Can Be Permanently  
Write Protected or Put in EPROM-Emulation Mode  
(Write to 0)  
• Switchpoint Hysteresis and Filtering to Optimize  
Performance in the Presence of Noise  
● Minimalist 1-Wire Interface Lowers Cost and  
Interface Complexity  
• IEC 1000-4-2 Level 4 ESD Protection  
(±8kV Contact, ±15kV Air, typ)  
• 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 125kbps  
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
