Features

? New generation, multizone Time-of-Flight (ToF) sensor with low-power and

enhanced distance ranging performance

– Multizone distance measurement capability with either 4x4 or 8x8

separate zones

– Autonomous low-power mode with interrupt programmable threshold to

wake up the host

– Ranging up to 400 cm, with enhanced performance under ambient light

– Multitarget detection and distance measurement in each zone

– Histogram processing and algorithmic compensation to minimize or

remove the impact of cover glass crosstalk

– Motion indicator for each zone to show if targets have moved and how

they have moved

– Frame rate capability of 60 Hz

? Fully integrated miniature module with wide field of view (FoV)

– New generation, high-power emitter: 940 nm invisible light VCSEL

(vertical-cavity surface-emitting laser) and integrated analog driver

– 65° diagonal square FoV using DOEs (diffractive optical elements) on

both transmitter and receiver

– Receiving array of SPADS (single photon avalanche diodes)

– Low-power microcontroller running firmware

– Size: 6.4 x 3.0 x 1.75 mm

? Easy integration

– Single reflowable component

– 1.8 V core supply and 3.3 V AVDD supply required

– Optional 1.2 V or 1.8 V IOVDD interface voltage levels

– I2C (up to 1 MHz) or SPI (up to 20 MHz) interface

– Compatible with wide range of cover glass materials

– Can be hidden behind a dark cover glass

Applications

? Robotic applications in difficult environments including SLAM, wall tracking,

small object detection, cliff prediction, and floor type recognition

? System activation under ambient light for smart buildings and smart lighting.

For example: user detection to wake up devices

? Content management for tanks, loads in trucks, and waste bins

? Liquid level monitoring

? Gesture recognition

? Keystone correction for video projectors

? Devices requiring better ambient light immunity

? Augmented reality/Virtual reality enhancement. Dual camera stereoscopy and

3D depth assistance thanks to multizone distance measurements

? IoT and battery powered devices for user and object detection

? LAF (laser assisted autofocus), which enhances the camera AF system speed

and robustness, especially in difficult low light or low contrast scenes.
