24-bit absolute pressure sensing in a 2x2 mm footprint
The STMicroelectronics LPS22HBTR is a MEMS nano pressure sensor delivering 24-bit digital output over I²C or SPI, covering an absolute pressure range of 260 to 1260 hPa (3.77 to 18.27 PSI).
Digital interface and board integration
Both I²C and SPI are available on the same 10-pin HLGA package (2x2 mm, 10-HLGA), so the same BOM position serves either bus architecture by strapping the CS pin. The no-port style means the sensor die is exposed through a hole in the package lid — the board designer must provide a sealed cavity or O-ring if the sensor is used in condensing or liquid environments.
