DESCRIPTION

The Microchip Technology Inc. 24AA16 is a 1.8 volt 16K

bit Electrically Erasable PROM. The device is orga-

nized as eight blocks of 256 x 8-bit memory with a 2-

wire serial interface. Low voltage design permits oper-

ation down to 1.8 volts with standby and active currents

of only 3

µA and 1 mA, respectively. The 24AA16 also

has a page-write capability for up to 16 bytes of data.

The 24AA16 is available in the standard 8-pin DIP and

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

ages.
