AT24C256
Serial EEPROM provides 256 Kbit of nonvolatile storage organized as 32,768 by 8 bits. The device uses an I2C-compatible two-wire serial interface with standard, fast, and Fast Mode Plus clock operation. It operates from a 1.7 V to 5.5 V supply over the industrial temperature range and supports 64-byte page writes with hardware write protection. The memory is rated for high write endurance and long data retention.
