DESCRIPTION

The Microchip Technology Inc. 24AA04/08 is a 4K bit or

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

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

a two wire serial interface. Low voltage design permits

operation down to 1.8 volts with standby and active cur-

rents of only 3 µA and 1 mA respectively. The 24AA04/

08 also has a page-write capability for up to 16 bytes of

data. The 24AA04/08 is available in the standard 8-pin

DIP and both 8-lead and 14-lead surface mount SOIC

packages.
