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.

The ICU-30201 is a high-performance ultrasonic Time-of-Flight sensor that is ideal for measuring the range of objects between 30cm and 9.5m, and offers a customizable field-of-view of up to 180º. It has a sample rate of 75 samples per second at 2 meters, and 18 samples per second at 9 meters. It comes in a 5.17 × 2.68 × 0.9 mm LGA package, and includes an integrated DSP for signal processing.

The T5838 is a low noise, high AOP digital Pulse Density Modulation (PDM) microphone using a fifth-order Σ‑Δ modulator. It also features Acoustic Activity Detect (AAD), a new ultra-low power edge processing feature consuming as low as 20 µA.

6-Axis High performance IMU supporting highly accurate external clock input, that helps to reduce system level sensitivity error, improve orientation measurement from gyroscope data, reduce ODR sensitivity to temperature and device to device variation.
