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 (1.8V 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. This device is capable of
both random and sequential 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 plastic DIP and
SOIC packages.
