Description:

The Microchip Technology Inc. 24AA256/24LC256/

24FC256 (24XX256*) is a 32K x 8 (256 Kbit) 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 also has a page write capability of up to 64

bytes of data. This device is capable of both random

and sequential reads up to the 256K boundary.

Functional address lines allow up to eight devices on

the same bus, for up to 2 Mbit address space. This

device is available in the standard 8-pin plastic DIP,

SOIC, TSSOP, MSOP and DFN packages.
