STMicroelectronics STTS2002 2.3V Memory Module
Temperature Sensor

STMicroelectronics STTS2002 2.3V Memory Module Temperature Sensor features an integrated 2KB SPD EEPROM and an operating temperature range of -40ºC to +125ºC. STMicroelectronics STTS2002 Memory Module Temperature Sensor is targeted for DIMM modules in mobile personal computing platforms, servers, and other industrial applications. The digital temperature sensor has a programmable 9-12 bit analog-to-digital converter (ADC) that monitors and digitizes the temperature to a resolution of up to 0.0625ºC. The temperature sensor in the STMicroelectronics STTS2002 is specified for operating at supply voltages from 2.3V to 3.6V. Operating at 3.3V, the typical supply current is 160µA.
