The CAN-USB/2 module is an intelligent CAN interface with an ARM 7 microcontroller for the local management of CAN data. The module supports the USB 2.0 High Speed interface with data rates of 480 Mbit/s. The ISO 11898-compliant CAN interface allows a data transfer rate of a maximum of 1 Mbit/s. The CAN interface is electrically isolated from other potentials by means of a digital isolator and a DC/DC converter. Software drivers for Windows® 2K/XP/Vista/7/8 (32/64 bit) are included in delivery. Linux® kernel ≥ 2.6 is supported via Linux CAN (SocketCAN) and NTCAN wrapper library. Drivers for other operating systems are available on request. The firmware can be updated from the PC. Updates are available on the esd website. Libraries for the higher layer protocols CANopen and J1939 are available. Additional free-of-charge esd CAN tools for Windows offer efficient setup and analysis of CAN applications and networks.

The CAN-PCI/402-2-FD is a PC board designed for the PCI bus that features two electrically isolated high-speed CAN FD interfaces according to ISO 11898-1:2015. The CAN FD interfaces are driven by the ISO 16845:2004 certified esdACC implemented in the Intel® 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. The board is fully backwards compatible with CAN and can be also used in Classical CAN applications. 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 CAN-PCI/402-2-FD can be operated for example in Hypervisor environments. The board provides high resolution hardware timestamps.
