Reverse Costing Analysis of ST’s LPS331AP MEMS-Based Pressure-Sensing Device

Published on June 17, 2013 at 5:21 AM

Research and Markets has announced the addition of the "STMicroelectronics LPS331AP - Reverse Costing Analysis" report to their offering.

Barometric pressure sensors are equipping more and more portable devices. These components sense the pressure of the atmosphere and help consumer products detect altitude variations indoor or improve the accuracy of altitude measurement in complement of GPS. They can also be used to refine local weather forecasting when used as a barometer.

ST's LPS331AP pressure-sensing device is manufactured using a proprietary MEMS technology, called VENSENS, that allows the pressure sensor to be fabricated on a monolithic silicon chip. This process eliminates wafer-to-wafer bonding. The sensing element in the LPS331AP is based on a flexible silicon membrane formed above an air cavity with a controlled gap and defined internal pressure. The membrane is very small compared to traditional silicon micro-machined membranes. The sensor and ASIC are packaged in a 3x3x1mm HCLGA.
