Freescale FXAS21000 Xtrinsic 3-Axis Digital Rate Gyroscope

Freescale FXAS21000 Xtrinsic 3-Axis
Digital Rate Gyroscope

Freescale's FXAS21000 Xtrinsic 3-Axis Digital Rate Gyroscope is a small, low-power, 3-axis yaw, pitch, and roll angular rate gyroscope. The full-scale range is adjustable from ±200°/s to ±1600°/s. It features both I2C and SPI interfaces. FXAS21000 is capable of measuring angular rates up to ±1600°/s, with output data rates (ODR) from 1.5625 to 200Hz. The device may be configured to generate an interrupt when a user-programmable angular rate threshold is crossed on any one of the enabled axes. FXAS21000 is available in a plastic QFN package; the device is guaranteed to operate over the extended temperature range of –40°C to +85°C.

  • 1.95V to 3.6V supply voltage; 1.62V to 3.6V digital interface voltage
  • I2C and SPI interfaces; I2C Normal and Fast modes (100 and 400kHz), SPI at up to 2MHz (3- and 4-wire modes)
  • 192 byte (32 X/Y/Z sample) FIFO buffer with circular and triggered operating modes
  • Output data rates (ODR) from 1.5625 to 200Hz; integrated antialiasing filter ensures that output signal bandwidth = ODR/2

  • Angular rate sensitivity of 0.2°/s in ±1600°/s FSR mode
  • Low power standby mode
  • Rate threshold interrupt
  • Integrated self-test function
  • No external charge-pump capacitor needed
  • –40°C to +85°C operating temperature range
