Comet A65 SOM

System On Module (SOM) featuring the latest Agielx™ 5 SoC FPGA

The Comet A65 SOM is Terasic's latest SOM, featuring Altera's largest-scale Agilex™ 5 SoC FPGA (656K logic).

With HPS/ARM processor, 12GB of LPDDR4 memory, and ample I/O, it's ideal for industrial applications such as medical devices, robotics, and smart cameras.

Applicable to mass production

The Comet A65 SOM is available in a mass-production-ready, certified commercial grade, making it ideal for high-volume deployment as an edge device.

Designed for long-term use, it features a robust construction that ensures stable operation even in harsh environments.

Development tools included

A free license for Altera® Quartus® Pro Edition is included, allowing you to develop and compile at no additional cost.
