CAN35414HR RTD Embedded Technologies Quad-Channel PCI Express CAN Bus Module

The RTD Embedded Technologies CAN254 / CAN 354 Series Quad-Channel PCI Express CAN Bus Modules offer dual Mini PCI Express sockets, designed to permit integration of third party Mini PCI Express CAN bus modules into rugged PCIe/104 and PCI/104-Express systems and enclosures. Mini PCI Express (also referred to as PCI Express Mini Card, Mini PCIe, mPCIe, and PEM) is a form factor for devices which supports both PCI Express and USB 2.0 connectivity.

The CAN25414HR and CAN35414HR are built with two PEAK-System PCAN-miniPCIe dual-channel CAN bus controller modules installed in the two Mini PCI Express sockets, permitting a total of four CAN bus channels per board. The CAN25412HR and CAN25412HR are built using one PEAK-System PCAN-miniPCIe dual-channel CAN bus controller module, permitting a total of two CAN bus channels per board, and leaving the second Mini PCI Express socket available for a third party module selected by the user.

An onboard PCIe Gen 2 switch provides a x1 PCI Express connection to each of the dual sockets on the CAN25410HR and CAN35410HR, using only one upstream x1 PCI Express link from the bus. Similarly, an onboard USB 2.0 hub generates a USB 2.0 link for each of the dual sockets using only one USB 2.0 link from the bus. Additional links on the PCIe Gen2 switch and USB 2.0 hub are utilized to repopulate the x1 PCI Express link and USB link these devices use from the host, making these links available to the next x1 PCI Express or USB peripheral in the system.

For devices installed in the dual mini PCI Express sockets of the CAN25410HR or CAN35410HR, a pair of 1x10 10-pin connectors is available per socket, permitting breakout of additional I/O on third party modules that do not use the socket interface (e.g. CAN bus). Such connections may be easily wired to these 1x10 headers, and accessed by external devices via a corresponding set of 0.1" 10-pin I/O connectors on the board edge.

The dual sockets on the CAN25410HR and CAN35410HR permit mounting of full and half-length Mini PCI Express modules, allowing maximum flexibility with the specification.
