TDK Introduces SmartMotion Ultra-Performance Series of 6-Axis MEMS Motion Sensors for Consumer Applications

● ICM-45xxx 6-axis motion sensor series with the industry's lowest power consumption

● Using the world's first BalancedGyro (BG) technology

● With high-precision on-chip self-calibration function

    TDK announces the InvenSense ICM-45xxx SmartMotion™ Ultra High Performance (UHP) series of 6-axis MEMS motion sensors that introduce on-chip self-calibration, the industry's lowest power consumption, and the world's innovative BalancedGyro™ (BG) technology . TDK's BalancedGyro technology is the first-of-its-kind innovative gyroscope MEMS architecture enabling superior vibration suppression and temperature stability performance, an enhancement never before seen in a consumer gyroscope. The technology could greatly facilitate applications such as robotic vacuum cleaners and smartphones, with negligible gyro drift due to temperature and vibration fluctuations.

    The ICM-45xxx series also offers a new self-calibration feature that allows sensitivity calibration to be done on-chip, resulting in a 10x improvement in gyro sensor lifetime accuracy, which can reduce overall rotation angle errors, especially when taking pictures. Optical Image Stabilization (OIS) applications that accurately compensate for hand rotation errors. Self-calibration can also save a lot of cost and the effort of performing extensive factory calibration for sensitivity errors.

    In addition, the ICM-45xxx series can provide a 6-axis motion sensor with lower power consumption than competing products, and compared with other IMUs in the industry, this series of products can make the gyroscope work 40% longer under the same energy condition. The product family also introduces an ultra-low-power accelerometer mode for low-power wake-up applications. Today's wearables, headsets, etc. require a motion sensor that can detect high-intensity workouts, activities, and gestures with the lowest possible power consumption, which requires gyroscopes and accelerometers to be always on, increasing power consumption. big. The ICM-45xxx bridges this gap by offering the lowest power consumer gyroscope in the industry today.

    Pankaj Aggarwal, vice president of product marketing for consumer motion sensors at TDK, said: "Today, innovation in MEMS technology is key to meeting the increasingly complex needs of the consumer market. With BalancedGyro technology and the industry's lowest power consumption, the ICM-45xxx series is leading the way in consumer The technology development of motion sensor-like.”

    The ICM-45xxx family includes three unique devices covering a wide range of consumer segments including smartphones, AR, VR, wearables and robotics. Some of the key high-performance applications supported by this family include optical image stabilization (OIS), head pose estimation, spatial audio, robotic navigation, and high-intensity activity monitoring, to name a few. The product family is also capable of supporting embedded motion functions (APEX) such as pedometer, wake on motion, free fall, tap detection and 8KB FIFO, enabling more intelligence and systems in a package size of 2.5mm x 3mm x 0.81mm energy-saving.
