The Microchip Technology Inc. 24AA512/24LC512/  
24FC512 (24XX512*) is a 64K x 8 (512 Kbit) Serial  
Electrically Erasable PROM, capable of operation  
across a broad voltage range (1.7V to 5.5V). It has  
been developed for advanced, low-power applications  
such as personal communications and data acquisi-  
tion. This device also has a page write capability of up  
to 128 bytes of data. This device is capable of both  
random and sequential reads up to the 512K boundary.  
Functional address lines allow up to eight devices on  
the same bus, for up to 4 Mbit address space. This  
device is available in the standard 8-pin plastic DIP,  
SOIJ and DFN packages.
