ICM-20690

6-Axis MotionTracking® Device for Optical Image Stabilization (OIS) applications

Note: The ICM-20690 is marked as EOL and is not recommended for new designs.

The ICM-20690 is a 6-axis MotionTracking device with a main Interface for UI and an Auxiliary interface configurable as SPI slave for Optical Image Stabilization (OIS) applications or as I²C Master to support other sensors such as compass or pressure sensor. It is available in a 2.5 × 3 × 0.91mm 14-pin LGA package.

• Concurrent UI+OIS with I²C/SPI Slave to host & Slave SPI at 20Mhz for OIS (low phase delay)
• Independent FSR selection for each interface
• OIS FSR range 32 to 250 for highest resolution
• Only solution with 4-axis OIS support concurrently
• Lowest gyro noise at 4 mdps
• Only 6-axis chip with 1% sensitivity tolerance that supports calibration-less production
• Best offset vs temperature performance
• EIS FSYNC support
• The ICM-20690 features a 1K-byte FIFO that can lower the traffic on the serial bus interface, and reduce power consumption by allowing the system processor to burst read sensor data and then go into a low-power mode.

Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and programmable interrupts. The device features I²C and SPI serial interfaces, a VDD operating range of 1.71 to 3.45V, and a separate digital IO supply, VDDIO from 1.71V to 3.45V.

• 3-Axis Gyroscope with independently programmable FSR of ±31.25, ±62.5, ±125, ±250, ±500, ±1000 and ±2000dps for UI and OIS paths
• 3-Axis Accelerometer with independently programmable FSR of ±2, ±4, ±8 and ±16g for UI path and ±1, ±2, ±4 and ±8g for OIS path
• Host interface: 8MHz SPI or 400kHz I²C slave
• Auxiliary interface: 20MHz SPI slave interface (e.g. interface to OIS controller) OR 400kHz I²C master interface (e.g. interface to external sensors)

• 1K byte FIFO buffer enables the application processor to read the data in bursts
• On-Chip 16-bit ADCs and Programmable Filters
• Digital-output temperature sensor
• VDD operating range of 1.71 to 3.45V
• MEMS structure hermetically sealed and bonded at wafer level
• RoHS and Green compliant
