DESCRIPTION

*WP pin available only on 24LC024. This

pin has no internal connection on 24LC025

The Microchip Technology Inc. 24LC024/24LC025 is a

2K bit Serial Electrically Erasable PROM with a voltage

range of 2.2V 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 10 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 24LC024/24LC025

devices on the same bus for up to 16K bits of contigu-

ous EEPROM memory. The device is available in the

standard 8-pin PDIP, 8-pin SOIC (150 mil), and TSSOP

packages.
