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
碌
A 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.
