●DESCRIPTION
●The Microchip Technology Inc. 24LC04B/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 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.
