3-axis digital accelerometer with a 2-axis digital gyroscope in a single device to provide a multi-sensor module with five degrees of freedom.
The combination improves sensing accuracy and reliability at reduced size and cost, opening new possibilities for high-precision motion detection-based applications in mobile phones, navigation systems, game controls and many other portable electronic devices.
The LSM320DL detects acceleration up to 16 g and angular rate up to 2000 dps along the pitch and yaw axes. The mechanical sensing structure has been designed to guarantee outstanding symmetry and resistance against mechanical and thermal stress, and to deliver optimum stability over time and temperature for zero-g offset, zero-rate and sensitivity.
Five degrees of freedom in a single device increases system robustness, which together with high thermal and mechanical stability and advanced power management options makes ST’s new multi-sensor module suitable for a wide range of consumer and industrial applications such as intuitive user interfaces in mobile phones, game consoles, pointers, remotes and other smart consumer devices; dead-reckoning and map-matching in advanced navigation systems; smart power saving and free-fall detection in portable electronics; and vibration monitoring and compensation.Addressing power constraints in battery-operated portable devices, the LSM320DL includes power-down and sleep modes and an embedded FIFO
(first-in first-out) memory block, which removes the need for continuous communication between the sensor module and the host processor. The device can operate with any supply voltage in the range of 2.4 to 3.6V.
The LSM320DL is available now, with unit pricing at $3.50 for volumes in the range of 1000 pieces. This product is intended for high-volume OEMs and ODMs and is not available through distribution.For further information on ST’s complete MEMS portfolio, see www.st.com/mems.
