Description

The 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 A and 1 mA, respectively. 24AA64 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 addresslines allow up to eight devices 24AA64 on the same bus, for upto 512 Kbits address space. The 24XX64 is available inthe 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.
