STMicroelectronics VL53L7CH & VL53L8CH

VL53L7CH and VL53L8CH are the perfect Time-of-Flight sensors enabling AI applications, with ultrawide 90° diagonal FoV (for VL53L7CH) and a wide 65° diagonal FoV (for VL53L8CH). 

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
• Highly configurable CNH in order to meet user expectations
• Wide ToF sensor with 65° field of view (FoV) for VL53L8CH
• Ultrawide ToF sensor with 90° field of view (FoV) for VL53L7CH

Additional 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 for VL53L8CH)
  • 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° (for VL53L8CH) and 90° (for VL53L7CH) field of view (FoV)
  • 45° x 45° square FoV (65° diagonal) and 60° x 60° square FoV (90° diagonal)
  • Autonomous low-power mode with interrupt programmable thresholds to wake up the host
  • Up to 350 cm (for VL53L7CH) and 400 cm (for VL53L8CH) 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 1.6 mm  (for VL53L7CH) and 1.75 mm (for VL53L8CH)
     
• Easy integration
  • Single reflowable component
  • For VL53L7CH flexible power supply options, single 3.3 V or 2.8 V operation, or combination of either 3.3 V or 2.8 V AVDD with 1.8 V IOVDD
