DESCRIPTION

BLOCK DIAGRAM

The Microchip Technology Inc. 24AA01 and 24AA02

are 1K bit and 2K bit Electrically Erasable PROMs.The

devices are organized as a single block of 128 x 8-bit

or 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 currents of only 3 µA and 1 mA,

respectively.The 24AA01 and 24AA02 also have page-

write capability for up to 8 bytes of data. The 24AA01

and 24AA02 are available in the standard 8-pin DIP

and 8-pin surface mount SOIC packages.
