2K 2.5V CMeOt4SUS.ceorial EEPROMs IN24LC02B
taSheDESCRIPTION
aIN24LC02B is a 2K-bit Electrically Erasable PROM. The device is organized as a single
.Dblock 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
wof only 5µA and 1mA respectively.
wThe IN24LC02B also has a page-write capability for up to 8 bytes of data.
w The IN24LC02B is available in the standard 8-pin DIP.
