Image of STMicroelectronics VL53L7CX Time-of-Flight Multizone Ranging Sensor Specially designed for applications requiring an ultrawide FoV, STMicroelectronics' VL53L7CX time-of-flight (ToF) sensor offers a 90° diagonal field of view (FoV). Based on ST's FlightSense technology, the VL53L7CX incorporates an efficient metasurface lens [diffractive optical elements (DOE)] placed on the laser emitter enabling the projection of a 60° x 60° square FoV onto the scene. Its multizone capability provides a matrix of 8 x 8 zones (64 zones) and can work at fast speeds (60 Hz) up to 350 cm.

The autonomous mode with programmable distance threshold combined with the ultrawide FoV makes the VL53L7CX perfect for any application requiring low-power user detection. ST's patented algorithms and innovative module construction allow the VL53L7CX to detect, in each zone, multiple objects within the FoV with depth understanding. ST histogram algorithms ensure cover glass crosstalk immunity beyond 60 cm.

Derived from the VL53L5CX, the pinouts and drivers of both sensors are compatible, ensuring a simple migration from one sensor to the other. Like all ToF sensors based on ST's FlightSense technology, the VL53L7CX records, in each zone, an absolute distance regardless of the target color and reflectance.

Housed in a miniature reflowable package that integrates a SPAD array, the VL53L7CX achieves excellent ranging performance in various ambient lighting conditions and for a wide range of cover glass materials. All of ST's ToF sensors integrate a VCSEL that emits a fully invisible 940 nm IR light, which is totally safe for the eyes (Class 1 certification).

The VL53L7CX is the perfect sensor for any application requiring ultra-wide FoV, like robotics, smart speakers, video projectors, and content management. The combination of the multizone capability and the 90° FoV can enhance new use cases like gesture recognition, SLAM for robotics, and low-power system activation for smart buildings.
