InvenSense’s 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 4 mm x 4 mm x 0.9 mm 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.
