3-Axis Digital Angular Rate
Gyroscope

FXAS21000

FXAS21000 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, with Output Data Rates (ODR) from 1.5625
to 200 Hz. It features both I2C and SPI interfaces. The device
may be configured to generate an interrupt when a userprogrammable angular rate threshold is crossed on any one of
the enabled axes.
