DESCRIPTION
The Microchip Technology Inc. 24AA64/24LC64
(24xx64*) is a 8K x 8 (64K bit) Serial Electrically Eras-
able PROM capable of operation across a broad volt-
age 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 32 bytes of data.
This device is capable of both random and sequential
reads up to the 64K boundary. Functional address lines
allow up to eight devices on the same bus, for up to 512
Kbits address space. This device is available in the
standard 8-pin plastic DIP, 8-pin SOIC (150 and
208 mil), and 8-pin TSSOP.
