34AA04

4K I²C^™Serial EEPROM with Software Write-Protect

Device Selection Table

Description

The Microchip Technology Inc. 34AA04 is a 4 Kbit

Electrically Erasable PROM which utilizes the I²C serial

interface and is capable of operation across a broad

voltage range (1.7V to 3.6V). This device is JEDEC

JC42.4 (EE1004-v) Serial Presence Detect (SPD)

compliant and includes reversible software write

protection for each of four independent 128 x 8-bit

blocks. The device features a page write capability of

up to 16 bytes of data. Address pins allow up to eight

devices on the same bus.
