TECHNICAL DATA
4K/8K 2.5V CMOS Serial EEPROMs
IN24LC04B/08B
DESCRIPTION
IN24LC04B/08B is a 4K-or 8K-bit Electrically Erasable PROM. The device is organized as two or four blocks of 256 x
8 bit memory with a two wire serial interface. Low voltage design permits operation down to 2.5 volts with standby and
active currents of only 5µA and 1mA respectively. The IN24LC04B/08B also has a page-write capability for up to 16
bytes of data. The IN24LC04B/08B is available in the standard 8-pin DIP.
