Product Summary
The STSC1 is a digital temperature sensor designed
especially for applications requiring a highly accurate
temperature measurement. Sensirion’s CMOSens^®
technology offers a complete sensor system on a single
chip, consisting of a bandgap temperature sensor, analog
and digital signal processing, A/D converter, calibration
data memory, and a digital communication interface
supporting I²C fast mode.
The ultra-small, 2 × 2 × 0.7 mm³ DFN package enables
applications in even the most limited of spaces. The
sensor covers a temperature measurement range of –40
to 125 °C. The typical accuracy of the temperature
sensor is ±0.3°C. The operation voltage of 1.8 V and an
average power consumption below 8.6µW make the
STSC1 suitable for mobile or wireless applications
running on the tightest power budgets.
Benefits of Sensirion’s CMOSens^® Technology
 High reliability and long-term stability
 Sensor system on a single chip
 Designed for mass production
 Optimized for lowest cost
 Low signal noise
