ToF sensor suits ultra-long-range applications

It is a high-performance ToF sensor for ultra-long-range applications, measuring distances from 30 cm to 9.5 m with millimetre accuracy.

It enhances contextual awareness and reliability in diverse environments, including smart homes, robotics, and obstacle avoidance.

The sensor delivers accurate measurements in any lighting condition, from full sunlight to complete darkness, and can detect optically transparent surfaces such as glass and clear plastics.

It supports multi-object detection with a customizable field-of-view (FOV) up to 180°.

The sensor also features a 53 kHz piezoelectric micromachined ultrasonic transducer (PMUT) — a second-generation ultra-low power System-on-Chip (SoC) — and a 40 MHz integrated CPU for on-chip algorithms including range finding, human presence, and wake-on approach.

Sample rate is 75 samples per second at two meters and 18 samples per second at nine meters.

With ultra-low power consumption (22µA to 318µA depending on the number of samples per second), the ICU-30201 helps extend battery life in devices including smart speakers, meeting room devices, and smart door locks.

A single bottom port package for receiving and transmitting allows for easy mechanical integration.

The ICU-30201 sensor comes in a compact 5.17 × 2.68 × 0.9 mm LGA package and includes an integrated digital signal processor (DSP). It is compatible with standard surface mount device (SMD) reflow and has an operating temperature range of -40°C to +85°C.
