http://www.microchip.com/stellent/images/mchpsiteimages/dwnfolder.gif24AA64/24LC64/24FC64 Data SheetThe Microchip Technology Inc. 24AA64 is a 64 Kbit electrically Erasable PROM. The device is organized as a single block of 8Kex 8-bit memory with a 2-wire serial interface. Low-voltage 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, lowpower 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, TDFN and MSOP packages. The 24XX64 is also available in the 5-lead SOT-23 package.
