Description

The Microchip Technology Inc. 24AA024/24LC024/

24AA025/24LC025 is a 2 Kbit Serial Electrically

Erasable PROM with a voltage range of 1.8V to 5.5V.

The device is organized as a single block of 256 x 8-bit

memory with a 2-wire serial interface. Low current

design permits operation with typical standby and

active currents of only 1

µA

and 1 mA, respectively.

The device has a page write capability for up to 16

bytes of data. Functional address lines allow the

connection of up to eight 24AA024/24LC024/

24AA025/24LC025 devices on the same bus for up to

16K bits of contiguous EEPROM memory. The device

is available in the standard 8-pin PDIP, 8-pin SOIC

(150 mil), TSSOP and MSOP packages.
