The AMC-CAN4 features four CAN High-Speed interfaces according to ISO 11898-2. The CAN interfaces are electrically isolated against the controller potential and against each other. CAN status is displayed by two LEDs for each CAN channel placed at the RJ45 connectors.
The four independent CAN nets according to ISO 11898-1 are driven by the esd Advanced CAN Core (esdACC) CAN controller implemented in the Xilinx Spartan 3e FPGA.
Controlled by the FPGA the AMC-CAN4 supports bus mastering as an initiator, meaning that it is capable of initiating write cycles to the host CPU`s RAM independent of the CPU or the system DMA controller. This results in a reduction of overall latency on servicing I/O transactions in particular at higher data rates.
CAN layer 2 (CAN-API) software drivers are available for Windows, RTX, VxWorks, QNX and Linux supporting up to 24 CAN nets. Drivers for other operating systems are available on request. The CANopen software package is available for Windows, VxWorks, QNX and Linux.
