overview DO 254 IP



The APB_ARINC429 module is an ARINC429 to APB Bridge.
It allows a system with an embedded APB bus to be connected to an external ARINC429 interface.
The hardware item only covers digital layers of the ARINC 429 Protocol bus architecture.
With its unique internal architecture the digital core is optimized for low gate count and low latency applications. The APB_ARINC429 matches major needs of any critical application and mainly those which require a DO-254 DAL-A compliance in the aerospace area. The development has been done according to the DO-254/ED-80 guidelines. This component has been developed, verified and licensed by SILKAN.

APB_ARINC429 Key features are as follows:
• Developed according to DO-254/ED-80 guidance. Compliant DAL A.
• Compliant with ARINC 429-16 Protocol published on September 27, 2001.
• Compliant with AMBA 3 APB Protocol v1.0.
• Compliant with Mark 33 Digital Information Transfer System.
• Microsemi® (Actel®) Corporation property.
