The Industry’s First Three-axis High-resolution Accelerometer

Published:2011/11/3 21:37:00 Author:Phyllis From:SeekIC

STMicroelectronics, a global leader serving customers across the spectrum of electronics applications and the leading suppliers of MEMS for consumer and portable applications, recently introduced the LIS3DSH accelerometer with two embedded finite-state machines which enable custom motion recognition inside the sensor, raising the bar in reducing system complexity and power consumption in motion-sensitive mobile phones and other smart consumer devices.

The LIS3DSH accelerometer, the industry’s first three-axis high-resolution accelerometer, provides extremely accurate output across full-scale ranges of plus or minus 2g/plus or minus 4g/plus or minus 8g/plus or minus 16g and boasts excellent stability over time and temperature. Other features include power-down and sleep modes, and embedded FIFO memory block, a temperature sensor, and a self-test function.

In battery-hungry portable devices, it is crucial as integrated processing capability in MEMS sensors decreases power consumption at the system level. The LIS3DSH accelerometer also brings more freedom and flexibility to the design of motion-enabled consumer electronics.

The embedded finite-state machines allow the user to implement customized motion-detection-based applications with a high level of flexibility, reducing the workload of the microprocessor by moving programming functionality inside the sensor. These basic programs indentify specific motions or gestures, custom-defined in the instruction set that runs inside the sensor firmware, and initiate associated actions or applications.

Leveraging the same micromachining technology process that ST has successfully applied to more than 1.6 million motion sensors already sold, ST’s LIS3DSH three-axis linear accelerometer with embedded finite-state machines will start mass production in Q1 2012, with unit pricing $1.2 in quantities of 1000 pieces.
