$Features & Applications

The STTS2004 is targeted for DDR4 DIMM modules in servers, desktops, and mobile personal computing platforms. The STTS2004 can interface to buses which have multiple devices on a shared bus.

The device can achieve substantial power savings by using the software-programmed shutdown mode. The digital temperature sensor has a programmable 9-12 bit analog-to-digital converter (ADC). The typical accuracies over these temperature ranges are: ±2 °Cover the full temperature measurement range of –20 °C to 125 °C, ±1 °C in the +40 °C to +125 °C active temperature range, and ±0.5 °C in the +75 °C to +95 °C monitor temperature range. The temperature sensor in the STTS2004 is specified for operating at supply voltages from 2.2 V to 3.6 V. Operating at 3.3 V, the typical supply current is 160 μA (includes I2C communication current).
