DESCRIPTION
The IS24C64-2 is a 1.8V (1.8V-5.5V) 64K-bit (8192 x 8)
Electrically Erasable PROM, IS24C64-3 is a 2.5V (2.5V-
5.5V) 64K-bit (8192 x 8) Electrically Erasable PROM,
IS24C32-2 is a 1.8V (1.8V-5.5V) 32K-bit (4096 x 8)
Electrically Erasable PROM and the IS24C32-3 is a 2.5V
(2.5V-5.5V) 32K-bit (4096 x 8) Electrically Erasable
PROM.
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.
