Description:
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.

Preliminary
*24XX1025 is used in this document as a generic part number
for the 24AA1025/24LC1025/24FC1025 devices.
This device is capable of both random and sequential
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.
