SE98A Overview
The NXP Semiconductors SE98A measures temperature from −40 °C and +125 °C with JEDEC Grade B ±1 °C accuracy between +75 °C and +95 °C municating 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 ponent specification. The SE98A thermal sensor operates over the VDD...
