An intelligent quad channel CAN controller PMC, the PMC408 meets the CAN2.0B and CANaerospace standards, as well as the ARINC-825 protocol. A widely used fieldbus in automotive and industry applications, CAN is increasingly being used more and more in aerospace. CAN also contains the specification to be a subsystem bus for ARINC 664 Part 7 networked IMA (Integrated Modular Avionics) architectures, a standard used by large aircraft builders like Airbus and Boeing.

The PMC408 is built around the MPC8247 PowerQUICC II processor with four MCP2515 CAN controllers. Each CAN channel is independently isolated using its own DC/DC converter and opto-coupler. The PMC408 also features a digital input channel for 1PPS timing signal, which can be used for time synchronization.

The PMC408 is also available as a conduction cooled version – the ccPMC408.
