The STTS2002 is ST's 2.3V memory module temperature sensor with a 2K byte SPD EEPROM. It is forward compatible with JEDEC TSE 2002a2 and backward compatible with STTS424E02.
The STTS2002 is a 2.3V memory module temperature sensor with an integrated 2 Kb SPD EEPROM, designed for DIMM modules in mobile personal computing platforms, servers, and industrial applications. It is forward compatible with JEDEC TSE 2002a2 and backward compatible with the STTS424E02.
The device features a programmable 9-12 bit analog-to-digital converter (ADC) with a typical accuracy of +2°C over the full operating range of -40°C to +125°C. It includes a 2 Kb serial EEPROM organized as 256 x 8 bits, functionally identical to the M34E02, supporting permanent and reversible software data protection for the lower 128 bytes.
