The 24LC256-I/P is a 8 pin dip integrated circuit that can hold 256K of memory (32x8 EEPROM).
Description: 2 Wire Serial Communication (I2C) EEPROM - The back bone of any microprocessor project. These 8 pin chips need only two wires to communicate and retain their data even with power failure. Use the 256K EEPROM for some serious data storage!
