1 / 12 page Preliminary data This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. July 2009 Doc ID 15813 Rev 2 1/12 12 LPR550AL MEMS motion sensor: dual axis pitch and roll ±500°/s analog gyroscope Features ■ 2.7 V to 3.6 V single-supply operation ■ Wide operating temperature range (-40 °C to +85 °C) ■ High stability overtemperature ■ Analog absolute angular-rate output ■ Two separate outputs for each axis (1x and 4x amplified) ■ Integrated low-pass filters ■ Low power consumption ■ Embedded power-down ■ Embedded self-test ■ High shock and vibration survivability ■ ECOPACK® RoHS and “Green” compliant (see Section 5) Applications ■ Pointing devices, remote and game controllers ■ Gaming applications ■ Motion control with user interface ■ Industrial and robotics Description The LPR550AL is a low-power dual-axis micromachined gyroscope capable of measuring angular rate along pitch and roll axes. It provides excellent temperature stability and high resolution over an extended operating temperature range (-40 °C to +85 °C). The LPR550AL has a full scale of ±500 °/s and is capable of detecting rates with a -3 dB bandwidth up to 140 Hz. The gyroscope is the combination of one actuator and one accelerometer integrated in a single micromachined structure. It includes a sensing element composed by single driving mass, kept in continuous oscillating movement and able to react when an angular rate is applied based on the Coriolis principle. A CMOS IC provides the measured angular rate to the external world through an analog output voltage, allowing high level of integration and production trimming to better match sensing element characteristics. ST’s gyroscope family leverages on robust and mature manufacturing process already used for the production of micromachined accelerometers. ST is already in the field with several hundreds million sensors with excellent acceptance from the market in terms of quality, reliability and performance. LPR550AL is provided in plastic land grid array (LGA) package. Several years ago ST pioneered successfully the usage of this package for accelerometers. Today ST has the widest manufacturing capability and strongest expertise in the world for production of sensor in plastic LGA package. LGA-16L (5x5x1.5mm) Table 1.
