Accelerometer enables motion control in clam-shell phones
Housed in 1 mm high package, MEMS-based Model LIS3LV02DL provides digital output, which eliminates need for dedicated A/D converter on each input channel, and enables sensor to share interfaces with other devices. Able to measure tilt and acceleration along all 3 axes, device provides [+ or -]2.0 g and [+ or -]6.0 g full-scale acceleration ranges. It embeds host of smart features, including free-fall and wake-up flag, adjustable bandwidth, and direction detection.
GENEVA, Switzerland, February 13 -- MEMS-based Sensor Packs World-class Performance, Smart Features, and Digital Output Into 1mm-high package
STMicroelectronics (NYSE:STM), a leading supplier of MEMS(Micro-Electro-Mechanical System) devices, today announced that it has expanded its portfolio of three-axis accelerometers with the thinnest digital-output sensor on the market. Embedding high performance and smart functionality in a 1-mm-high package, ST's LIS3LV02DL opens new possibilities for advanced motion-based applications in ever-more popular, thin-profiled clamshell mobile phones.
MEMS-based accelerometers have enabled the introduction of high-performance, cost-effective motion-based user interfaces in mobile applications, including gesture recognition, motion-activated scrolling, and navigation on the phone display. ST's new ultra-slim 3D sensor with digital output extends these advanced capabilities to the clamshell form factor, which is expected to account for 41% of the estimated 750 million handsets sold worldwide in 2006, and represent the majority of mobile phone sales by 2008.
The LIS3LV02DL is the newest member in ST's market-unique family of three-axis accelerometers with a standard SPI/I2C digital interface. The digital output streamlines communication with the baseband chip; it eliminates the need for a dedicated A/D converter on each input channel and enables the sensor to share interfaces with other devices, thereby saving further space in slim-form-factor systems.
