Description
AI
The VL53L8CX is an 8x8 multizone, ToF ranging sensor, which enhances performance under ambient light with a reduced power consumption. Based on STMicroelectronics' FlightSense technology, the sensor is designed to provide accurate ranging up to 400 cm with a 65° diagonal FoV.
The VL53L8CX integrates a powerful new generation VCSEL, and two advanced metasurface lenses. The hardware is housed in an innovative "all in one" module. This enables a wider variety of high-performance usecases, such as low-power system activation, gesture recognition, SLAM for robotics, liquid level monitoring, and many more.
Thanks to STMicroelectronics' patented algorithms, the VL53L8CX can detect and track multiple targets within the FoV, with a 64-zone depth measurement. The STMicroelectronics' histograms ensure a cover glass crosstalk immunity above 60 cm.
Like all ToF sensors based on STMicroelectronics' FlightSense technology, the VL53L8CX measures an absolute distance regardless of the target color and reflectance.
The VL53L8CX supports SPI and I²C interfaces for high frequency frame rates and short-boot times.
The VCSEL of the VL53L8CX emits fully invisible 940 nm IR light. Such VCSEL has a Class 1 certification that is safe for the eyes. Scene browsing and multizone detection are possible with the VL53L8CX. This is due to a software customizable detection array. It detects human presence quickly and at low-power. Such detection is known as a minidepth map.
