ST aims at motion interfaces
The LIS3L02D device is designed primarily for handheld terminals where it can be used to implement new motion-based user interfaces based on hand movements. This allows one-handed operation without styli, thumb keyboards or other input devices.
Other applications include toys, industrial equipment, robotics, automotive systems and appliances where sensing of movement, acceleration or inclination is needed.
The LIS3L02D includes a single-chip MEMS sensor plus a calibrated interface chip that senses changes in capacitance in the sensor and translates them into SPI or I2C serial digital outputs.
Accelerometers based on silicon-micromachined MEMS technology exploit the changes in capacitance caused by the relative movement between structures created in the silicon, using wafer-processing.
The LIS3L02D operates on a 2.7-3.6V voltage. The device has an equivalent noise acceleration of better than 500microg. During transport and service it can withstand accelerations up to 3000g without damage, making it sufficiently shock resistant for mobile phone applications.
