24AA1025/24LC1025/24FC1025

1024K I²C^™CMOS Serial EEPROM

This device is capable of both random and sequential

Device Selection Table:

reads. Reads may be sequential within address bound-

aries 0000h to FFFFh and 10000h to 1FFFFh.

Functional address lines allow up to four devices on the

same data bus. This allows for up to 4 Mbits total

system EEPROM memory. This device is available in

the standard 8-pin PDIP and SOIJ packages.

R/W Control

The Microchip Technology Inc. 24AA1025/24LC1025/

24FC1025 (24XX1025*) is a 128K x 8 (1024K bit)

Serial Electrically Erasable PROM, capable of opera-

tion across a broad voltage range (1.8V to 5.5V). It has

been developed for advanced, low-power applications

such as personal communications or data acquisition.

This device has both byte write and page write

capability of up to 128 bytes of data.

*24XX1025 is used in this document as a generic part number

for the 24AA1025/24LC1025/24FC1025 devices.
