LeddarCore LCA3: A Highly Integrated, High-Performance LiDAR SoC

This 64-channel LiDAR control and acquisition system-on-chip enables sensor manufacturers developing their own signal processing software to design LiDAR solutions that meet the specific requirements of various applications by providing the core LiDAR functions they need in a highly integrated SoC.

With the ability to support various types of medium- to long-range LiDAR designs and components, including many options for light sources and wavelengths, photodetectors, illumination and beam steering methods, the hardware-agnostic LCA3 SoC enables multiple types of solid-state LiDARs, including flash and hybrid-flash configurations.

The on-chip accumulation feature reduces data rate by 92%, as it adds 4 bits to the 14 useful bit data for 16 accumulations instead of transferring 224 useful bits (16 x 14) per point. LCA3 SoC’s built-in functionalities also enhance SNR by up to 2.8 times for increased range. 

Using the low- to high-level drivers, retrofitting and programming the LeddarCore into existing LiDAR systems generates significant savings on cost, real estate and power consumption.

This functional-safe component can manage the full LiDAR acquisition or be controlled via an upcoming hardware trigger. LeddarCore SoC and other LiDAR components can be managed via the customer’s FPGA, microcontroller and operating system.
