TECHNICAL DATA

2K 2.5V CMOS Serial EEPROMs

IN24LC02B

DESCRIPTION

IN24LC02B is a 2K-bit Electrically Erasable PROM. The device is organized as a single

block of 256 x 8 bit memory with a two wire serial interface.

Low voltage design permits operation down to 2.5volts with standby and active currents

of only 5

µA and 1mA respectively.

The IN24LC02B also has a page-write capability for up to 8 bytes of data.

The IN24LC02B is available in the standard 8-pin DIP.
