DESCRIPTION

The Artschip technology Inc. 24AA256/24LC256 (24xx256*) is

a 32K x 8 (256k 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 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, and 8-pin SOIC (208 mil) packages.

PACKAGE TYPE

PDIP

SOIC
