STEVAL-MKI047V1 STMicroelectronics

LPY550AL MEMS motion sensor: dual axis pitch and yaw 500/s analog output gyroscope Preliminary data Features 2.7 V to 3.6 V single supply operation Very extended operating temperature range (-40C to +85C) LGA-16L (5x5x1.5mm) High stability overtemperature Absolute analog rate output The LPY550AL has a full scale of 500 /s and is capable of detecting rates with a -3 dB bandwidth Two separate outputs for each axis up to 140 Hz. (1x and 4x amplified) Integrated low-pass filters The gyroscope is the combination of one actuator and one accelerometer integrated in a single Low power consumption micromachined structure. Embedded power-down It includes a sensing element composed by single Embedded self-test driving mass, kept in continuos oscillating High shock and vibration survivability movement and able to react when an angular rate is applied based on the Coriolis principle. ECOPACK RoHS and Green compliant (see Section 5) A CMOS IC provides the measured angular rate to the external world through an analog output Applications voltage, allowing high level of integration and production trimming to better match sensing Pointing devices, remote and game controllers element characteristics. Gaming applications ST gyroscope family leverages on robust and Motion control with user interface mature manufacturing process already used for the production of micromachined accelerometers. Industrial and robotics ST is already in the field with several hundreds Description million sensors with excellent acceptance from the market in terms of quality, reliability and The LPY550AL is a low-power two-axis performance. micromachined gyroscope able to measure angular rate along pitch and yaw axes. LPY550AL is provided in plastic land grid array (LGA) package. Several years ago ST pioneered It provides excellent temperature stability and successfully the usage of this package for high resolution over extended operating accelerometers. Today ST has the widest temperature range (-40C to +85C). manufacturing capability and strongest expertise in the world for production of sensor in plastic LGA package. Table 1.
