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, DFN and 14-lead TSSOP
packages.
