RAR15XC Flight-Certifiable Avionics Interface

Dual Protocol XMC for MIL-STD-1553, ARINC 429, and avionics discretes


Certifiable communications simplified

The RAR15XC flight-certifiable avionics communications board delivers high-density MIL-STD-1553 and ARINC 429 data bus communications as well as avionics discrete I/O. Its small XMC mezzanine form factor is easily integrated onto other compatible boards, like the SBC314C flight-certifiable single board computer.

The RAR15XC is pin-compatible with the RAR15X and provides operational capability for full integration into aircraft systems. It is engineered to meet the demands of the most safety-critical applications and provides high-level functionality to reduce the complexity of the application programming.

Big function, small space

MIL-STD-1553 standard features include 48-bit receive message time tagging, extensive BC & RT link-list structures, error detection, automatic/manual RT Status Bit and Mode Code responses, along with advanced BC functionality.

ARINC 429 standard features include independent 64 message transmit and receive buffers and a message scheduler providing flexibility in generating ARINC bus traffic scenarios.
