DESCRIPTION

The Microchip Technology Inc. 24LC04B/08B is a 4K or

8K bit Electrically Erasable PROM. The device is orga-

nized as two or four blocks of 256 x 8-bit memory with

a 2-wire serial interface. Low voltage design permits

operation down to 2.5 volts with typical standby and

active currents of only 5 µA and 1 mA respectively. The

24LC04B/08B also has a page-write capability for up to

16 bytes of data. The 24LC04B/08B is available in the

standard 8-pin DIP and both 8-lead and 14-lead surface

mount SOIC packages.
