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.
