ST24C08, ST25C08 are 8 Kbit I2C bus EEPROM products manufactured by ST Microelectronics. The product has 1 million erase/write cycles and 40 years of data retention. The product provides standard version and hardware write control version. The write control of the standard version is controlled by the MODE pin, and the write control of the hardware write control version is controlled by the WC pin. The product is manufactured in ST Microelectronics's Hi-Endurance Advanced CMOS process, which has high durability and high performance.
This document is a technical specification covering the ST24/25C08 and ST24/25W08 series of 8 Kbit electrically erasable programmable memories (EEPROM). These devices are organized as four blocks of 256 x 8 bits and utilize an I2C compatible two-wire serial interface. They support byte, random, sequential read modes, as well as byte, multibyte, and page write operations.
