ICM-20649 Worlds First Wide-Range 6-Axis MEMS MotionTracking Device for Sports and High Impact Applications GENERAL DESCRIPTION APPLICATIONS Many of todays wearable and sports solutions, which analyze Sports the motion of a users golf or tennis swings, soccer ball kicks, Wearable Sensors or basketball activities, require higher than currently available High Impact Applications 2000 dps (degrees per second) FSR for gyroscope and 16g FEATURES FSR for accelerometer to better insure that critical data is not lost at the point of high impact or high speed rotation. The 3-Axis gyroscope with programmable FSR of ICM-20649 6-axis inertial sensor offers the smallest size, 500 dps, 100 dps, 2000 dps, and 4000 dps lowest profile and lowest power in conjunction with industry 3-Axis accelerometer with programmable FSR of leading high FSR. 4g, 8g, 16g, and 30g User-programmable interrupts With an extended FSR range of 4000 dps for gyroscope and 30g for accelerometer, the ICM-20649 enables precise Wake-on-motion interrupt for low power operation analysis of contact sports applications providing continuous of applications processor motion sensor data before, during and after impact providing 512-byte FIFO buffer enables the applications more accurate feedback processor to read the data in bursts On-Chip 16-bit ADCs and Programmable Filters The ICM-20649 is the worlds first wide-range 6-axis DMP Enabled: MotionTracking device for Sports and other High Impact o SMD, Step Count, Step Detect, Activity applications. It is available in a 3x3x0.9 mm 24-pin QFN Classifier, RV, GRV package. o Calibration of accel/gyro/compass 2 ORDERING INFORMATION Host interface: 7 MHz SPI or 400 kHz I C Digital-output temperature sensor PART TEMP RANGE PACKAGE VDD operating range of 1.71V to 3.6V ICM-20649 40C to +85C 24-Pin QFN MEMS structure hermetically sealed and bonded at Denotes RoHS and Green-Compliant Package wafer level BLOCK DIAGRAM RoHS and Green compliant TYPICAL OPERATING CIRCUIT nCS SCLK SDI GND NC 1 18 NC 2 17 NC NC NC 3 16 ICM-20649 NC 4 15 NC 5 14 NC NC 6 13 VDD NC 1.8 3.3VDC C2, 0.1 F 1.8 3.3VDC C1, 0.1 F C3, 0.1 F Motion Analysis Pod Architecture SDO InvenSense Inc.
