Description

The Microchip Technology Inc. 24AA64/24LC64 (24XX64*) is a 64 Kbit Electrically Erasable PROM. The device is organized as eight blocks of 1K x 8-bit memory with a 2-wire serial interface. Low voltage design permits operation down to 1.8V with standby and active currents of only 1 µA and 1 mA respectively. It has been developed for advanced, low power appli- cations such as personal communications or data acquisition. The 24XX64 also has a page-write capabil- ity 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 and MSOP packages.
