The Microchip Technology Inc. 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.
