Block circuit diagram of CAN-M.2/402-2-FD
The CAN-M.2/402-2-FD is an M.2 Card, that features two electrically isolated CAN FD interfaces.
The optional adapter CAN-PCIeMini/402-DSUB comes with a DSUB9 connector, selectable on-
board CAN termination and an adapter cable.
CAN-M.2/402-2-FD 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 Intel 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-M.2/402-2-FD can be operated
for example in Hypervisor environments.
The CAN-M.2/402-2-FD provides high resolution 64-bit hardware timestamps for CAN messages.
The CAN layer 2 (NTCAN-API) drivers for Windows
®
and Linux
®
are included in the scope of
delivery. See “Order Information” on page 31 for availability of other drivers.
Customized options are available for customized series production in reasonable quantities.
