CPC-PCIe is a passive CAN plug-in board for PCIe x1 slots. Designed for industrial applications, with a robust and cost efficient construction, the CPC-PCIe supports one, two or four CAN channels that can be operated independently with different data rates.
The interface utilizes the NXP SJA1000 CAN controller, which offers good diagnostic attributes. The CPC-PCIe maps the CAN controller(s) directly in the address space of the PC and allows access of the CAN messages with low latencies. Existing software for the supported CAN controller can easily be adapted.
CAN communication with CPC-PCIe may be handled either in interrupt controlled mode or in polled mode; interrupt channels are assigned automatically (Plug & Play). Optionally, CPC-PCIe is available with galvanic separation between PC and CAN bus. A galvanic separation between the CAN channels is also possible by separate DC/DC converters.
As a member of the CPC family of PC to CAN interface products, the CPC-PCIe benefits from the CPC Software Interface Framework, which provides a consistent host software interface environment for Windows and Linux based applications that is independent of the PC hardware interface being used.
