VL53L8CH
Description
The VL53L8CH is the perfect Time-of-Flight sensor enabling AI applications, with enhanced performance under ambient light with a wide 65° diagonal FoV. The compact and normalized histogram (CNH) innovative data output is specially designed for artificial intelligence (AI) applications requiring multizone raw data from a high performance multizone ToF sensor.
Key Features
- Compact and normalized histogram (CNH) data output for AI - Multizone data output up to 64 separate zones - Histogram output with signal count for each bin - Histogram size programmable up to 128 bins - Minimum bin width down to 37 mm - Maximum frequency up to 30 Hz through I²C or SPI - Ambient IR light level reported for each zone - All Time-of-Flight (ToF) processed data (distance, signal amplitude, reflectance etc.) are available, in addition to CNH
- Highly configurable CNH in order to meet user expectations - 64 zones with 18 bins at 15 Hz - 32 zones with 36 bins at 15 Hz - 16 zones with 48 bins at 25 Hz
- Wide ToF sensor with 65° field of view (FoV) - 45° x 45° square FoV (65° diagonal) - Autonomous low-power mode with interrupt programmable thresholds to wake up the host - Up to 400 cm ranging - Motion indicator for each zone to detect if targets have moved and how they have moved
- Fully integrated miniature module - Emitter: 940 nm invisible-light vertical-cavity surface-emitting laser (VCSEL) - Diffractive optical elements (DOE) on both transmitter and receiver enabling square FoV - Receiving array of single photon avalanche diodes (SPADs) - Low-power microcontroller running firmware - Size: 6.4 x 3.0 x 1.75 mm
- Easy integration - Single reflowable component - Requires 1.8 V core supply and 3.3 V AVDD supply - Optional 1.2 V or 1.8 V IOVDD interface voltage levels - I²C (up to 1 MHz) or SPI (up to 3 MHz) interface - Compatible with a wide range of cover glass materials - Driver compatible with VL53L7CH - Pin-to-pin compatible with VL53L8CX
