InvenSense® to Showcase Revolutionary Motion Interface Solutions at CES 2013

Optical Image Stabilization (OIS): InvenSense will demonstrate how its highly precise OIS gyroscope detects and accounts for slight hand jitter and the gyroscope’s immunity to interference from audible frequencies such as music or ambient noise. This technology is ideal for smartphone manufacturers seeking the same level of OIS that is available in digital still cameras.

ICM-45686

High-Precision 6-Axis MEMS MotionTracking® Device

The ICM-45686 is an ultra high‑performance 6‑axis MEMS motion sensor family with the world’s first BalancedGyro™ technology and lowest power consumption. The sensor combines a 3‑axis gyroscope and a 3‑axis accelerometer in a compact 2.5 × 3 × 0.81 mm package.

The BalancedGyro technology by TDK is the first‑of‑its‑kind gyroscope MEMS architecture that enables supreme vibration rejection and temperature stability performance, an enhancement never seen before in a consumer gyroscope.

ICM-45686 provides higher full-scale range upto 4000 dps and 32g, better temperature stability to reduce temperature related drift, and high-performance features such as Real Time Clock Input and 18/19 bit high-resolution FIFO.

This family offers the world’s lowest power 6‑axis motion sensor. This allows the gyroscope to be on 40% of the times more than any other gyroscope in the industry. This also offers the very first Gyroscope Low Power Mode, enabling ~200uA of 6-axis IMU current consumption, making it the top choice for wearables, hearables and any battery driven IoT application.

It has a configurable host interface that supports I3C℠, I²C and SPI serial communication, and an AUX interface that supports SPI slave mode for connection to OIS controllers or I²C master mode for connection to external sensors.
