The Temp-Log 4 Click Board™ measures temperature and features the SE97B IC, an accurate temperature sensor IC with integrated EEPROM. Besides the thermal sensor, this IC is equipped with additional 256 bytes of EEPROM, integrated on the same die. This can be a very useful option for some applications: it allows auxiliary data to be stored within the same IC, so no additional EEPROM IC is required. This can simplify the design greatly, reducing the number of required external components.
