The CAN-PCIeMini/402-2 is an add-in PCI Express Full-Mini Card, that features two electrically
isolated CAN High-Speed interfaces. The PCI Express® Mini Card CAN-PCIeMini/402-2-FD
comes with two CAN FD interfaces. The optional adapter CAN-PCIeMini/402-DSUB9 offers a
DSUB9 connector and on board CAN termination.
The CAN FD version is fully backwards compatible with CAN and can also be used in Classical
CAN applications.

The independent CAN nets are driven by the ISO 16845:2004 certified esdACC (esd Advanced
CAN Core) implemented in the Altera FPGA.
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-PCIeMini/402-2(-FD) can be
operated for example in Hypervisor environments.
The CAN-PCIeMini/402-2(-FD) provides high resolution 64-bit hardware timestamps for CAN
messages.

CAN layer 2 (CAN-API) software drivers for CAN-PCIeMini/402-2 for Windows and Linux are
included in the scope of delivery. See “Order Information” on page 29 for availability of other
drivers.

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

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