STMicroelectronics’ ultra-compact piezoresistive absolute pressure sensor functions as a digital output barometer

STMicroelectronics’ LPS27HHTW is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer. The device also embeds a temperature sensor to monitor ambient temperature. The LPS27HHTW comprises a sensing element and an IC interface that communicates through I²C, MIPI I3CSM, or SPI from the sensing element to the application.

Features

  • Pressure sensor with water-resistant package
  • Potting gel and grounded metal cap
  • 260 hPa to 1260 hPa absolute pressure range
  • Current consumption down to 4 µA
  • Absolute pressure accuracy: 0.5 hPa
  • Low-pressure sensor noise: 0.7 Pa
  • Temperature accuracy: ±1.5°C
  • Embedded temperature compensation
  • 24-bit pressure data output
  • ODR from 1 Hz to 200 Hz
  • SPI, I²C, or MIPI I3C interfaces
  • Embedded FIFO
  • Interrupt functions: data-ready, FIFO flags, pressure thresholds
  • Supply voltage: 1.7 V to 3.6 V
  • ECOPACK lead-free compliant
