QST QMI8658A

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.
