STMicroelectronics is now extending the M24 serial EEPROM family by providing four of the compatible devices in teh industry standards that are 4 ball WLCSP  (Wafer Level Chip Scale Package) footprint. These new additions are also claimed to connect two or more 4-pin EEPROMs to the same I2C bus and with other hard wired I2C addresses . This will be in short allowing the devices for teh purposes like rear and front camera modules.

The M24 series is available with operating voltages from 5.5 to 1.7V and will be operating in the temperature segment of -40 to 85, 105, 125, and 145°C. The chips come in SO8N, TSSOP, leadless UFDFPN5 and 8, ultrathin WLCSP packages.
