General description 
The NXP Semiconductors SE97 measures temperature from −40 °C to +125 °C with JEDEC Grade B ±1 °C accuracy between +75 °C and +95 °C and also provide 256 bytes of EEPROM memory communicating via the I2C-bus/SMBus. It is typically mounted on a Dual In-line Memory Module (DIMM) measuring the DRAM temperature in accordance with the new JEDEC (JC-42.4) Mobile Platform Memory Module Temperature Sensor Component specification and also replacing the Serial Presence Detect (SPD) which is used to store memory module and vendor information.
The SE97 thermal sensor operates over the VDD range of 3.0 V to 3.6 V and the EEPROM over the range of 3.0 V to 3.6 V write and 1.7 V to 3.6 V read.
