MEMS-based sensor from STMicroelectronics packs world-class performance, smart features and digital output into 1mm-high package

MEMS-based accelerometers have enabled the introduction of high-performance, cost-effective motion-based user interfaces in portable devices, including gesture recognition, motion-activated scrolling, and navigation on the display. ST’s new ultra-slim 3D sensor with digital output extends these advanced capabilities.

The LIS3LV02DL is a member of 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.

ST’s LIS3LV02DL embeds a host of smart features, including a free-fall and wake-up flag, adjustable bandwidth and direction detection.

Adjustable bandwidth provides optimized performance for different frequencies. The bandwidth can be flexibly changed with a software command, allowing designers to effectively combine measurements of slow and fast motions, such as tilt and vibrations, in one application. When a threshold is crossed along any of the three axis, the embedded direction detection helps quickly understand in which direction the sensor is moving before any data calculations are made.

The sensor can measure both tilt and acceleration along all three (x, y, z) axis at a very low noise level and minimized power consumption, which is especially critical in battery-operated portable systems.

Manufactured in ST’s proprietary THELMA15 technology, the LIS3LV02DL provides both +/-2.0g and +/-6.0g full-scale acceleration ranges, which can be changed by software command even during operation. The device offers high temperature stability and tight offset tolerances and its robust design provides very high immunity to vibration and a shock resistance up to 10,000g.

The LIS3LV02DL is supplied in 16-pin LGA and QFN28 packages and readily available.
