STMicroelectronics LPS27HHTW MEMS Pressure Sensor
STMicroelectronics LPS27HHTW MEMS Pressure Sensor is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer. The LPS27HHTW Sensor also embeds a temperature sensor to monitor the ambient temperature. The LPS27HHTW includes a sensing element and an IC interface that communicates through I2C, MIPI I3CSM, or SPI from the sensing element to the application. The sensing element detects absolute pressure and consists of a suspended membrane manufactured using a dedicated process developed by ST.
The STM LPS27HHTW is housed in a ceramic LGA package with a metal lid. The device is guaranteed to operate over a temperature range extending from -40°C to +85°C. The ceramic LGA package is holed to allow external pressure to reach the sensing element. The gel inside the IC protects the electrical components from water, and the metal cap is grounded electrically for better ESD robustness.
