2-Kb I

C EEPROM for DDR2 DIMM Serial Presence Detect  
FEATURES  
DEVICE DESCRIPTION  
■ Supports Standard and Fast I2C Protocol  
■ 1.7 V to 5.5 V Supply Voltage Range  
■ 16-Byte Page Write Buffer  
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 16-byte page write buffer and supports  
both the Standard (100 kHz) as well as Fast (400 kHz)  
I2C protocol.  
■ Hardware Write Protection for entire memory  
■ Software Write Protection for lower 128 Bytes  
■ Schmitt Triggers and Noise Suppression Filters  
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).  
on I2C Bus Inputs (SCL and SDA).  
■ Low power CMOS technology  
■ 1,000,000 program/erase cycles  
■ 100 year data retention  
In addition to Permanent Software Write Protection,  
the CAT34C02 also features JEDEC compatible  
ReversibleSoftwareWriteProtectionforDDR2Serial  
Presence Detect (SPD) applications operating over  
the 1.7 V to 3.6 V supply voltage range.  
■ RoHS-compliant packages  
■ Industrial temperature 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.
