Description
The QMI8658A is a complete 6D MEMS inertial
measurement unit (IMU). With tight board-level
gyroscope sensitivity of ±3%, gyroscope noise density
of 13 mdps/√Hz, and low latency, the QMI8658A is ideal
for consumer and industrial applications.
The QMI8658A incorporates a 3-axis gyroscope and a 3-
axis accelerometer. It provides a host-processor interface
supporting I3C, I2C and 3-wire or 4-wire SPI.
With its built-in digital functionality, low power, and small
size, the QMI8658A is the ideal part for applications
requiring motion-based functionality.
