EEPROM 24c256 is a 256K-bit Serial CMOS EEPROM. EEPROM 24c256 is internally organized as 32,768 words of 8 bits each. Catalyst’s advanced CMOS technology substantially reduces device power requirements. The 24WC256 features a 64-byte page write buffer. The device operates via the I2 C bus serial interface and is available in 8- pin DIP or 8-pin SOIC packages.EEPROM 24c256 supports the I2C Bus data transmission protocol. This Inter-Integrated Circuit Bus protocol of EEPROM 24c256 defines any device that sends data to the bus to be a transmitter and any device receiving data to be a receiver. The transfer is controlled by the Master device which generates the serial clock and all START and STOP conditions for bus access. The EEPROM 24c256 operates as a Slave device. Both the Master device and Slave device can operate as either transmitter or receiver, but the Master device controls which mode is activated.
