STMicroelectronics has introduced a new generation of three-axis linear accelerometers. The versatile, low-power MEMS-based LIS331 sensing devices provide complete output flexibility and embedded smart features, meeting the exploding demand for miniaturised motion-sensing solutions in the consumer and industrial markets. The 3x3x0.9mm plastic package effectively addresses the space and weight constraints of portable electronic devices. The accelerometers deliver high performance at low power consumption, and their ultra-compact robust design provides very high immunity to vibration and shock survivability up to 10,000g. These motion sensors are suitable for a wide range of applications in the consumer and industrial markets, including motion user interfaces in mobile and gaming devices, free-fall detection for hard-disk-data protection, and vibration monitoring and compensation in white-goods appliances. The sensors have dedicated highly programmable interrupt lines.
