PURPOSE AND SCOPE
This document is a product specification, providing a description, specifications, and design related information on the ICM-20608-
G™ MotionTracking device. The device is housed in a small 3x3x0.75mm 16-pin LGA package.
PRODUCT OVERVIEW
The ICM-20608-G is a 6-axis MotionTracking device that combines a 3-axis gyroscope, and a 3-axis accelerometer in a small 3x3x0.75mm (16-pin LGA) package. It also features a 512-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. ICM-20608-G, with its 6-axis integration, enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices, guaranteeing optimal motion performance for consumers.
The gyroscope has a programmable full-scale range of ±250, ±500, ±1000, and ±2000 degrees/sec. The accelerometer has a userprogrammable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g. Factory-calibrated initial sensitivity of both sensors reduces production-line calibration requirements.
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. Communication with all registers of the device is performed using either I2C at 400kHz or SPI at 8MHz.
By leveraging its patented and volume-proven CMOS-MEMS fabrication platform, which integrates MEMS wafers with companion CMOS electronics through wafer-level bonding, InvenSense has driven the package size down to a footprint and thickness of 3x3x0.75mm (16-pin LGA), to provide a very small yet high performance low cost package. The device provides high robustness by supporting 10,000g shock reliability.
