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

boundaries 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, SOIC and SOIJ packages.

Description:

The Microchip Technology Inc. 24AA1025/24LC1025/

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

Serial Electrically Erasable PROM, capable of

operation across a broad voltage range (1.7V 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.
