Compact 14 pin LGA QST QMI8658A 6D MEMS inertial measurement unit with wide bandwidth sensors and large FIFO buffer
Product Overview
The QMI8658A is a complete 6D MEMS inertial measurement unit (IMU) featuring a low-noise, wide-bandwidth 3-axis gyroscope and a 3-axis accelerometer. With tight board-level gyroscope sensitivity, low noise density, and low latency, it is ideal for consumer and industrial applications requiring motion-based functionality. Its integrated motion co-processor supports features like Pedometer, Tap, Any-Motion, No-Motion, and Significant-Motion detection. The device offers flexible host interfaces (MIPI I3C, I2C, 3-wire/4-wire SPI), digitally programmable data rates and filters, low power modes, and a large FIFO buffer for reduced system power dissipation. It is available in a compact 2.5 x 3.0 x 0.86 mm 14-pin LGA package.
