✅Product features

Ultra-low noise + high stability Excellent noise level in the same series, strong ability to suppress offset caused by temperature drift, SMT welding deformation, and vibration, suitable for attitude detection and head tracking. Wafer-level sealing MEMS structure, strong impact resistance.

Multi-mode low power support for motion wake-up WOM, sensor sleep when stationary, and automatic wake-up once motion is detected, greatly extending the battery life of the device; The gyroscope can be turned off separately, and only the accelerometer will work.

The APEX hardware has rich built-in algorithms for motion event detection, which does not require the MCU to continuously sample, and can directly output events such as step counting, falling, tilting, and gestures, thus reducing the computing pressure on the main controller.

The multi-interface is compatible with I2C/SPI/ I3C three interfaces, which can meet the needs of traditional MCU and the new generation of I3C high-speed peripherals. Built-in FSYNC frame synchronization input, suitable for camera electronic stabilization EIS scenes.

✅Typical application scenarios

TWS Bluetooth earbuds, smart glasses, smart wristbands

VR/AR device posture tracking

Remote control, game controller, motion sensing

Internet of Things motion sensors, asset posture monitoring

✅Series differentiation (ICM-42507-C vs. ICM-42517-P)

ICM-42707-C: LGA14, regular consumer version, mainstream stock model, preferred for wearing headphones

ICM-42707-P: Same chip core, different package / pin definition, some driver software is slightly different, the performance indicators of the two are basically the same

✅Design considerations

MSL level 3, moisture sensitivity needs to be controlled before reflow soldering to avoid solder pad delamination;

LGA has no pins, stress should be considered in PCB pad design, PCB bending will introduce sensor offset;

When it is close to the area with strong vibration such as the power source and motor, structural vibration reduction should be done to reduce the vibration noise;

The interrupt pin is open drain, and an external pull-up resistor is required.
