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.
I2C is a trademark of Philips Corporation.
