Description:

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-

voltage design permits operation down to 1.7V, with

standby and active currents of only 1

A

and 3 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, SOIJ, TSSOP, DFN, TDFN and MSOP

packages. The 24XX64 is also available in the 5-lead

SOT-23, and Chip Scale packages.

100 kHz for V

<2.5V.

400 kHz for V
