CAT34C02  
2 kb I2C EEPROM for DDR2  
DIMM Serial Presence  
Detect  
Description  
http://onsemi.com  
The CAT34C02 is a 2 kb Serial CMOS EEPROM, internally  
organized as 16 pages of 16 bytes each, for a total of 256 bytes of 8 bits  
each.  
It features a 16byte page write buffer and supports both the  
2
Standard (100 kHz) as well as Fast (400 kHz) I C protocol.  
Write operations can be inhibited by taking the WP pin High (this  
protects the entire memory) or by setting an internal Write Protect flag  
via Software command (this protects the lower half of the memory).  
In addition to Permanent Software Write Protection, the  
CAT34C02 also features JEDEC compatible Reversible Software  
Write Protection for DDR2 Serial Presence Detect (SPD)  
applications operating over the 1.7 V to 3.6 V supply voltage range.  
The CAT34C02 is fully backwards compatible with earlier  
DDR1 SPD applications operating over the 1.7 V to 5.5 V supply  
voltage range.
