24AA64/24LC64/

24FC64 (24XX64*) is a 64 Kbit Electrically Erasable

PROM. The device is organized as a single block of 8K

x 8-bit memory with a 2-wire serial interface. Low-volt-

age design permits operation down to 1.7V, with

standby and active currents of only 1

μA and 1 mA,

respectively. It has been developed for advanced, low-

power applications such as personal communications

or data acquisition. The 24XX64 also has a page write

capability for up to 32 bytes of data. Functional address

lines allow up to eight devices on the same bus, for up

to 512 Kbits address space. The 24XX64 is available in

the standard 8-pin PDIP, surface mount SOIC, TSSOP,

DFN and MSOP packages.
