Application Scenarios & Design Considerations

256Kbit and 128Kbit Serial I2C Bus EEPROM With Three Chip Enable Lines

Alternative Part Number

  • 24LC256-I/ST --: Same 256Kbit I2C EEPROM in TSSOP-8 package, widely available and pin-compatible with the ST part.
  • CAT24C256WI-GT3 --: 256Kbit I2C serial EEPROM in SOIC-8, functionally equivalent with comparable speed and voltage range.
  • AT24C256C-SSHM-T --: 256Kbit I2C EEPROM in SOIC-8, drop-in functional replacement with similar timing and endurance.
  • AT24C256C-XHLM-T --: 256Kbit I2C EEPROM in the same TSSOP-8 package with compatible pinout and 1.7V-5.5V supply range, a widely available drop-in alternative.
