Serial EEPROM

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 A 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

and MSOP packages.
