1024-Bit, 1-Wire EEPROM  
DS2431  
General Description  
Features  
♦ 1024 Bits of EEPROM Memory Partitioned Into  
®
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 commu-  
nication 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.  
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  
♦ IEC 1000-4-2 Level 4 ESD Protection ( 8ꢀk  
Contact, 15ꢀk ꢁir, ꢂypical)  
♦ Reads and Writes Over a Wide koltage Range  
from 2.8k to 5.25k from -40°C to +85°C
