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.
