InvenSense three-axis gyroscopes are the world’s first single-chip, digital-output, 3-axis MEMS devices optimized for consumer applications. All devices feature three 16-bit analog-to-digital converters (ADCs) for digitizing the gyro outputs, a full-scale range up to ±2000 degrees per second (dps), programmable low-pass filters, I²C or SPI serial interfaces, low-voltage operation (from 2.1V to 3.6V), and small 4x4x0.9mm QFN packages. The devices in this family include the ITG-3050 and MPU-3050.
All devices provide filtered gyroscope data to their serial communications bus. The ITG-3050 supports raw 3-axis gyroscope data output only. The ITG-3050 features a secondary I²C master sensor bus, providing a direct upgrade path to the MPU family of products, which allow integration with InvenSense’s software solutions. The MPU devices feature an embedded Digital Motion Processor™ (DMP™) hardware accelerator engine, a minimum of 512 byte FIFO, and a secondary I²C-master sensor bus that interfaces to third party digital accelerometers to deliver a complete 6-axis sensor fusion output of processed acceleration and rotational motion data. The on-chip FIFO and sensor bus simplify system timing and lower system power consumption. The dedicated sensor bus allows the device to directly acquire data from the off-chip accelerometer without intervention from an external processor, while the FIFO allows the system microcontroller to burst read the sensor data and then enter sleep mode as the MPU collects more data.
Since handsets today are of multi-function nature, the three-axis MPU-3050 provides accurate 1:1 motion tracking for common applications such as gaming and location based services. Additionally, the 32-bit DMP engine delivers advanced User Interface (UI) functionality such as gesture and character recognition which can enable applications such as AirSign™ signature authentication, TouchAnywhere™ application and navigation control, and MotionCommand™ gesture shortcuts.
Designed for portable consumer devices such as game controllers and remote controls for Internet-connected TVs, the MPU-3050 with its DMP reduces system costs. By combining motion sensors and the DMP, the system processing requirements of motion-based handheld devices can typically be met by pairing the DMP with the processor built into the system’s RF chip. This provides a cost-reduced solution that is readily portable to many different platforms.
To assist in the rapid development and deployment of products using the MPU product families, InvenSense provides a MotionApps™ Platform that contains the core algorithm engines for motion processing, and includes an API layer which provides a simple interface into these engines. In addition, sample motion applications such as gesture recognition help speed time to market for consumer devices adding motion functionality. Evaluation boards and reference design kits are available for all the triple-axis devices.
