SE98 Datasheet SO-DIMM SMBus/I2C-bus temperature sensor

Manufacturer: NXP Semiconductors

General Description

The NXP Semiconductors SE98 measures temperature from −40 °C to +125 °C 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 Thermal Sensor Component specification.

Placing the Temp Sensor (TS) on DIMM allows accurate monitoring of the DIMM module temperature to better estimate the DRAM case temperature (Tcase) to prevent it from exceeding the maximum operating temperature of 85 °C.
