M65 (MEN MIKRO)

The M65 is based on the M-Module ANSI mezzanine standard. It can be used as an I/O extension in any type of bus system, i.e. CPCI, PXI, VME or on any type of stand-alone SBC. Appropriate M-Module carrier cards in 3U, 6U and other formats are available from MEN or other manufacturers. The M65 is a dual-intelligence full-CAN interface M-Module. The two channels are completely identical and independent. Each channel is built up with an MC68331 32-bit microcontroller, an i82527 CAN communications controller and local shared SRAM. The physical layer is ISO high-speed with up to 1Mbit/s. The physical interfaces are isolated from the system and from each other. The host can load and update the firmware in RAM. Communication is also done via shared SRAM and supported by window and pointer access mechanism. Interrupts are available in both directions from the M-Module to the host and from the host to the M-Module. CANopen firmware consists of the Vector Informatik protocol stack, which runs locally and thus reduces the load on the host. The corresponding driver software comes from MEN. It is based on MDIS (MEN Driver Interface System), which makes the M65 ready for use under WindowsNT, Linux and RTOS environments. MEN also provides comprehensive Intelligent CAN Layer 2 software, based on MDIS.
