65,536-bit/32,768-bit 2-WIRE SERIAL
CMOS EEPROM
ISSI
The IS24CXX (IS24C64-2, IS24C64-3, IS24C32-2 and
IS24C32-3) family is a low-cost and low voltage 2-wire
Serial EEPROM. It is fabricated using ISSI’s advanced
CMOS EEPROM technology and provides a low power
and low voltage operation. The IS24CXX family features
a write protection feature, and is available in 8-pin DIP and
8-pin SOIC packages.
FEATURES
Low Power CMOS Technology
– Standby Current less than 10 μA (5.5V)
