The CPCIserial-CAN/402-4-FD comes with four independent CAN FD interfaces via DSUB25 according to ISO 11898-1:2015. The CAN FD interfaces are driven by the ISO 16845:2004 certified esdACC (esd advanced CAN Core) implemented in the Altera FPGA.
With a higher bit rate in the data phase in combination with the increase of efficiency by a higher number of user-data bytes, CAN FD offers a higher data throughput while maintaining the benefits of Classical CAN.
CPCIserial-CAN/402-4-FD is fully backwards compatible with CAN and can also be used in Classical CAN applications.

CAN Data Management

The FPGA supports bus mastering (firstparty 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 CPCIserial-CAN/402-4-FD can be operated for example in Hypervisor environments.
The CPCIserial-CAN/402-4-FD provides high resolution 64-bit hardware timestamps for CAN messages.


An additional IRIG-B interface is equipped on the CPCIserial-CAN/402-4-FD-IRIG-B. It offers inputs for analog or RS-422 IRIG-B coded signals. Both are electrically isolated. IRIG-B evaluation is controlled by an 8051 microcontroller integrated in the FPGA.

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. QNX, RTX64 and VxWorks® can be ordered separately.

Higher Layer Protocols
(Classical CAN application only)
Higher Layer Protocols are available for many operating systems (see order info):
  • CANopen Master- and Slave-Stack
  • J1939
  • ARINC825

Additional free-of-charge esd CAN tools for Windows are downloadable from our website. The tools offer efficient setup and analysis of CAN applications and networks.
