ARINC 825 Controller
Design IP
Overview

SmartDV’s ARINC 825 Controller IP is a high-performance solution tailored for aerospace and defense applications requiring robust in-vehicle networking over CAN. Based on the CAN protocol and adapted for avionics, ARINC 825 enables reliable, real-time communication between critical systems while meeting the strict reliability and timing demands of modern aircraft.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. It supports key ARINC 825 features such as message prioritization, deterministic data transfer, and fault-tolerant communication, making it ideal for next-generation avionics systems.
