Customizable DO-254 ARINC-429 IP-Core

The product is a multi-channel, flexible and customizable ARINC-429 transmitter and receiver IP core for serial communication in airborne applications. The IP is developed, validated and licensed by Oxytronic.

The IP has been developed according to the RTCA/DO-254 ED-80 guidelines. These guidelines are required by the Airworthiness Certification Authorities (EASA and FAA) for hardware developments that need to be certified for the use in commercial aircraft equipment.

The IP incorporates a simple basic synchronous CPU interface which can be easily connected to your required interface. Each individual channel can be configured according to your specifications. Each channel contains a specific buffer (FIFO), which is part of the IP. This allows efficient data transfer between the CPU and the IP.
