MEN Mikro Elektronik F75P CompactPCI PlusIO SBC

The MEN Mikro Elektronik F75P CompactPCI PlusIO SBC unites the benefits of a 1oo2 multiprocessing system and the ruggedness and flexibility of the CompactPCI PlusIO standard on one single card. It is designed for rail applications and brings functional safety to the board level using redundant Intel Atom processors. While two redundant CPUs with independent RAM and flash memory increase system safety, a third processor controls the I/O interfaces.

Two of the total three Intel Atom E680T processors with 1.6 GHz and 512 MB DDR2 RAM are set up to be redundant, forming the safe control unit of F75P. The third Intel Atom with 1 GB DDR2 controls I/O. It passes on the commands to the interfaces that were sent by the two control CPUs across an FPGA-based communication interface.

Two supervisor units monitor the environmental conditions specified for the two control CPUs and put the system into a safe state, for instance if the maximum operating temperature was exceeded.

To increase the availability of a system, users can also connect two F75P SBCs to form a cluster.

Every F75P based system can be certified up to SIL 4 - a correspondent certificate by TÜV Süd is currently in preparation.

The standard front I/O of the unit comprises one VGA interface, two fast ethernet and two USB, while its rear gives access to one PCI Express port, four USB, one SATA and two fast ethernet.

Extended temperature range of -40 to +85°C, EN 50155 conformity, conformal coating and assembly of M12 connectors make the unit safe and robust - especially in rail applications where space is at a premium.
