The Microchip Technology Inc. 24AA64F/24LC64F

(24XX64F*) 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 read currents of only 1 μA and 400 μA,

respectively. It has been developed for advanced, low-

power applications such as personal communications

or data acquisition. The 24XX64F 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 24XX64F

is available in the standard 8-pin PDIP, surface mount

SOIC, TSSOP, TDFN and MSOP packages. The

24XX64F is also available in the 5-lead SOT-23

package.

Features:

• Single-Supply with Operation down to 1.7V for

24AA64F devices, 2.5V for 24LC64F devices

• Low-Power CMOS Technology:

- Read current 400 μA, max.

- Standby current 1 μA, max. (I-temp)

• 2-Wire Serial Interface, I²C™ Compatible

• Packages with 3 Address Pins are cascadable up

to 8 Devices
