With its latest software release 2014-B, dSPACE is now offering a new plug-on device – the DS4342 CAN FD Interface Module. This module includes the new CAN FD communication standard, which can be used with existing systems for rapid control prototyping (RCP) and hardware-in-the-loop (HIL) applications. The DS4342 uses FPGA technology to support current CAN FD features and to easily address future requirements.

Simple Hardware Extension Provides Investment Protection 

The new DS4342 CAN FD Interface Module can be easily integrated into dSPACE RCP systems such as MicroAutoBox II and dSPACE modular hardware for HIL systems. The module features two CAN FD channels that can also be used for classic CAN communication.

For large numbers of CAN FD channels, up to four DS4342 modules can be integrated on a DS4505 carrier board, which is also used for FlexRay communication. It is possible to combine FlexRay and CAN FD interface modules on the same carrier board. All this makes it easy to add CAN or CAN FD to existing systems, thereby protecting your investment.

Configuration via Existing Software

Similar to current CAN applications, CAN FD communication is configured graphically via the RTI CAN MultiMessage Blockset. Familiarity with this configuration software will enable developers to quickly add CAN-FD-specific information to their application.

Higher Bandwidth with CAN FD

The new CAN FD bus standard offers higher bandwidth than the established CAN protocol. The increased payload length of 64 bytes also increases the bus system's efficiency. The benefits of a classic CAN, namely flexibility and affordability, remain. Because the new bus protocol requires only few changes to the project configuration, using dSPACE tools keeps migration efforts minimal.
