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 16−byte page write buffer and supports both the

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.
