Angular rate output
The 16-bit / 24-bit angular velocity output data is provided in the 2’s complement expression. To use 24-bit output mode, it is necessary to switch to 24-bit mode with 1C address and then read twice with SafeSPI.
Detecting Axis and Output Polarity
This product detects an angular rate of a rotational movement. The correlation between a detecting axis of the angular rate and an output polarity is shown in Figure 2.

Interface
This sensor is specified to the SafeSPI – Serial Peripheral Interface for Automotive Safety.
Temperature Sensor Output
The 16-bit temperature output data is provided in the 2’s complement expression. Output data rate is 1 kHz.
