Triple Axis (X/Y/Z) MEMS Industrial Gyroscopes

Overview

InvenSense MPU-3300

InvenSense MPU-3300 triple-axis industrial gyroscopes are the world’s first single-chip, digital-output, 3-axis MEMS devices optimized for industrial applications. The devices feature three 16-bit analog-to-digital converters (ADCs) for digitizing the gyro outputs, a full-scale range up to ±450 degrees per second (dps), programmable low-pass filters, SPI or I²C serial interfaces, low-voltage operation, and small 4x4x0.9mm QFN packages.

The devices feature a 1024 byte FIFO, and a secondary I²C-master sensor bus that interfaces to third party digital accelerometers or other sensors. 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. The on-chip FIFO and sensor bus simplify system timing and lower system power consumption.

The MPU-3300 offers industry best performance in harsh industrial environments where extreme temperature ranges, and severe shocks are present. Applications that can be addressed with the MPU-3300 include Attitude Heading Reference Systems (AHRS) for Aerospace and Robotics; Navigation Systems for Industrial Vehicles, Aircraft, and Ships; Platform and Antenna Stabilization, Precision Robotics, Inventory Control Systems, Survey Instruments, Factory Equipment, Industrial Power Tools, Unmanned Aerial Vehicles, Precision Agriculture Machinery, Guidance and Steering Applications, and Construction Equipment.

Key features and benefits of the MPU-3300 include:

  • Bias Instability of 15 degrees/hour for precision industrial applications.
  • Operating temperature range of -40°C to +105°C
  • Low power consumption of less than 10mW for battery powered industrial devices.
  • Single chip 3-axis industrial gyroscope offers improved performance, size, and cost compared to single-axis gyroscopes.
