DESCRIPTION
The Microchip 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.
