1K-bit/2K-bit/4K-bit/8K-bit/16K-bit
2-WIRE SERIAL CMOS EEPROM
APRIL 2002
DESCRIPTION
The IS24CXX (refers to IS24C01, IS24C02, IS24C04,
IS24C08, IS24C16) 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.
The IS24C01 is a 1K-bit EEPROM; IS24C02 is a 2K-bit
EEPROM; IS24C04 is a 4K-bit EEPROM; IS24C08 is a 8K-
bit EEPROM; IS24C16 is a 16K-bit EEPROM.
The IS24C01 and IS24C02 are available in 8-pin MSOP
package. The IS24C01, IS24C02, IS24C04, and IS24C08
are available in 8-Pin TSSOP package.
Automotive data is preliminary.
