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.
