    Ambiq and TDK Deliver Industry-Leading Ultra-Low Power 6-Axis IMU

    Live demo of IMU with TDK SmartMotion® Technology Achieves Unrivaled Energy Efficiency on Ambiq’s Unique Energy Harvesting Reference Design at Embedded World 2024 on April 9-11, 2024

    Ambiq, a leader in exceptionally energy-efficient semiconductors for enabling AI on endpoint devices, partners with InvenSense, a TDK Group company that develops MEMS sensor solutions, to showcase an ultra-low power 6-Axis IMU on an energy harvesting reference design. 

    The Ambiq HarvestKit™ with the Apollo3 Blue SoC is an energy-harvesting reference design that functions as a high-performance edge compute node. It seamlessly executes AI and other complex algorithms while operating solely on energy harvested from its environment, eliminating the need for batteries. The reference design can be used for compelling use cases across various wireless-connected applications. 

    InvenSense‘s ICM-45605 is a 6-Axis IMU with an always-on gyroscope that uses 40% less power on Ambiq’s HarvestKit, setting new industry standards. It also includes an ultra-low power (ULP) accelerometer mode for low-power wake-up applications in wearable and IoT devices. It features superior vibration rejection and temperature stability with TDK BalancedGyroTM technology; a low noise gyroscope and accelerometer that achieves 3.8mdps/√Hz; 70µg/√Hz; user-programmable interrupts and digital filters; and more. The IMU is targeted for a range of motion-based functions including wake on motion, pedometer, tilt detection, low-g/high-g detection, freefall detection, significant motion detection, and single/double tap. 

    The HarvestKit reference design with the InvenSense ICM-45605 will be displayed at Ambiq’s booth during Embedded World 2024 in Hall 3, Booth #301. Please book a meeting to learn more.
