TECHNICAL DATA
2K 2.5V CMOS Serial EEPROMs
DESCRIPTION
KK24LC02B
is a 2K-bit Electrically Erasable PROM. The device is organized as a single
block of 256 x 8 bit memory with a two wire serial interface.
Low voltage design permits operation down to 2.5volts with standby and active currents
of only 5碌A(chǔ) and 1mA respectively.
The
KK24LC02B
also has a page-write capability for up to 8 bytes of data.
The
KK24LC02B
is available in the standard 8-pin DIP.
