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 8Kbit 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.

The A0 pin is not used by IS24C04. This pin can be left floating or tied to GND or Vcc. The IS24C08 only use A2 input for hardwire addressing and a total of two devices may be addressed on a single bus system. The A0 and A1 pins are not used by IS24C08. They may be left floating or tied to either GND or Vcc. These pins are not used by IS24C16. A0 and A1 may be left floating or tied to either GND or Vcc. A2 should be tied to either GND or Vcc. WP WP is the Write Protect pin. On the 24C01, 24C02, IS24C04 and 24C08, if the WP pin is tied to VCC the entire array becomes Write Protected (Read only). On the 24C16, if the WP pin is tied to Vcc the upper half array becomes Write Protected (Read only). When WP is tied to GND or left floating normal read/write operations are allowed to the device. SCL This input clock pin is used to synchronize the data transfer to and from the device. SDA The SDA is a Bi-directional pin used to transfer addresses and data into and out of the device. The SDA pin is an open drain output and can be wire-Ored with other open drain or open collector outputs. The SDA bus requires a pullup resistor to Vcc. A0, A1, A2 The A0, A1 and A2 are the device address inputs. The IS24C01 and IS24C02 use the A0, A1, and A2 for hardware addressing and a total of 8 devices may be used on a single bus system.
