Link to CAN-PCIe/402-FD Hardware Overview Overview of available CAN-PCIe/402-FD hardware versions

Drivers are available for several operating systems (see tables Software Support). Please contact our Sales Team for detailed information about the driver availability for your operating system or if you need drivers for other operating systems.
CAN driver availability for all esd CAN interfaces is listed here.

Wide Choice of Hardware Designs

The CAN-PCIe/402-FD is a PC board designed for the PCIe bus that features one (CAN-PCIe/402-1-FD) or two (CAN-PCIe/402-2-FD) electrically isolated CAN FD interfaces according to ISO 11898-2 via DSUB9 connectors.
Equipped with up to two CAN FD interfaces the board is available as low profile versions (CAN-PCIe/402-1-LP-FD and -LP2-FD).
In the CAN-PCIe/402-B4-FD version 4 CAN FD interfaces can be connected via one 37-pin DSUB connector.


The CAN FD interfaces are designed according to ISO 11898-1:2015. They are driven by the ISO 16845:2004 certified esdACC (esd advanced CAN Core), implemented in the Intel FPGA. All CAN FD versions are fully backwards compatible with CAN and can also be used in Classical CAN applications.

CAN Data Management

The FPGA supports bus mastering (first-party DMA) to transfer data to the host memory. This results in a reduction of overall latency on servicing I/O transactions in particular at higher data rates and a reduced host CPU load.
Due to the usage of MSI (Message Signaled Interrupts) the CAN-PCIe/402-FD can be operated for example in Hypervisor environments.
The CAN-PCIe/402-FD provides high resolution hardware timestamps.

Software Support

Windows and Linux (NTCAN-API)
The CAN layer 2 drivers for Windows and Linux are included in the scope of delivery.

Realtime OS (NTCAN-API)
CAN layer 2 drivers e.g. for QNX®, RTX® and RTX64® can be ordered separately.

Higher Layer Protocols (Classical CAN application only)
Higher Layer Protocols are available for many operation systems:

  • CANopen Master- and Slave-Stack
  • J1939
  • ARINC825

Customization on Request

Customized options are available for customized series production in reasonable quantities. Please contact our sales team for detailed information.
