CS1 - FPGA with Integrated AFDX/ARINC-664

The CS1 is a FPGA chip with an AFDX-protocol that can be installed directly onto a large variety of boards to build an AFDX end system, and eliminates the need for an additional module. Without modification, the CS1 can be adapted to realize specific requirements like, for example, AFDX/CAN, AFDX/Standard Ethernet, AFDX/ARINC 429 gateway solutions.

AFDX is a reliable, high-speed data bus commonly used in airborne applications for sending information between avionics subsystems. In modern aircraft avionic architectures, AFDX it is used to connect an arbitrary unit or module with other aircraft equipment, executing a full featured ARINC-653 application interface, which is equipped with a proprietary runtime executive. Its most important features are high data integrity, redundancy and deterministic behavior.

The CS1 meets all AFDX safety and performance requirements, which makes it ideal for safety-critical inflight data transfer. It also supports two full duplex AFDX networks based on standard IEEE802.3 Ethernet technology and applies protocol stack implementation. Up to 256 fully separated receive VLs and 64 transmit VLs allow for reliable packet transport and bounded transport latency.

The CS1, which can be ordered as an individual chip, is also available on the P522, a PMC I/O mezzanine card which is suitable for any PMC compliant host carrier board.
