DESCRIPTION
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
碌
A 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.
