DS2431  
1024-Bit 1-Wire EEPROM

GENERAL DESCRIPTION  
FEATURES  
®
!
1024 Bits of EEPROM Memory Partitioned into  
Four Pages of 256 Bits  
The DS2431 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 communicates over the single-  
conductor 1-Wire bus. The communication follows  
the standard Dallas Semiconductor 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.
