  • Details
  • Specification
  • Order information
  • High-speed CAN connection (ISO 11898-2)
  • Complies with CAN specifications 2.0 A/B and FD
  • CAN FD support for ISO and Non-ISO standards switchable
  • Extended operating temperature range from -40 to 85 °C (-40 to 185 °F)

The CAN FD adapter PCAN-USB FD allows the connection of CAN FD and CAN networks to a computer via USB. A galvanic isolation of up to 500 Volts decouples the PC from the CAN bus. The simple handling and its compact plastic casing make the adapter suitable for mobile applications.

The new CAN FD standard (CAN with Flexible Data rate) is primarily characterized by higher bandwidth for data transfer. The maximum of 64 data bytes per CAN FD frame (instead of 8 so far) can be transmitted with bit rates up to 12 Mbit/s. CAN FD is downward-compatible to the CAN 2.0 A/B standard, thus CAN FD nodes can be used in existing CAN networks. However, in this case the CAN FD extensions are not applicable.

The monitor software PCAN-View and the programming interface PCAN-Basic for the development of applications with CAN connection are included in the scope of supply and support the new standard CAN FD.


Since the first implementations of CAN FD, the protocol has been improved and is now included in the standard ISO 11898-1. The revised CAN FD standard is not compatible with the original protocol.

PEAK-System takes this into account by supporting both protocol versions with their CAN FD interfaces. If required, the user can switch to the CAN FD protocol used in the environment by software (Non-ISO and ISO).
