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 (1.8V 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,

SOIC, DFN and 14-lead TSSOP packages.
