CAT34C02

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.
