▶ Overview

The Comet A65 SOM is Terasic's new System-On-Module powered by Altera's largest Agilex™ 5 SoC FPGA with 656K logic elements. The SOM integrates an HPS/ARM subsystem, three 4GB high-throughput LPDDR4, two high-speed SEAM8 extension connectors, to support 71 LVDS, 245 LVCMOS and 24 transceivers. It enables embedded software/systems developers without FPGA expertise to develop various industrial applications, such as medical equipment, robotics, industrial communication and control, machine vision, smart camera and smart city.

Available in production-qualified and certified commercial grade, the Comet A65 SOM is purpose-built for your volume edge deployment and ruggedized for long life cycle operation.

Included with Comet A65 SOM  is a free license for Altera® Quartus® Pro Edition software — no additional license purchase is required. Developers can leverage full design and compilation capabilities of Quartus Pro without incurring licensing fees. Learn more about acquiring your free license.
