The LPS27HHTW is an ultra-compact piezoresistive absolute pressure sensor that can be used as a digital output barometer. The device also has a temperature sensor embedded to monitor ambient temperature. The LPS27HHTW consists of a sensing element and an IC interface that communicates with the application from the sensing element via I²C, MIPI I3CSM, or SPI. The sensing element for detecting absolute pressure consists of a suspended membrane manufactured by a special process developed by st.

     The LPS27HHTW comes in a ceramic LGA package with a metal lid. It is guaranteed to operate in the temperature range from -40°C to +85°C. The package has holes to allow external pressure to reach the sensing element. The gel inside the IC protects the electronic components from water and the metal cap is grounded for better ESD robustness.
