CAN FD integration on custom hardware

October 18, 2016 // By Christoph Hammerschmidt
A simple way of implementing CAN FD (Flexible Data Rate) in custom hardware designs is now offered by PEAK-System GmbH with the stamp module PCAN-Chip USB. The connection to the circuits is done via USB 2.0. The actual used physical CAN transmission is determined by the transceiver to be implemented by the developer.

The stamp module has a footprint of just 25 by 20 millimeters and is suitable for automatic insertion due to the single-sided component placement and the half-hole edge contacts. It can be operated in environments with the extended temperature range of -40 to +85 °C (-40 to +185 °F).

For the design phase, an evaluation board is available that provides a reference circuit of the stamp module. It contains connectors, indicator LEDs, jumpers, switches, and solder fields that can be used for testing purposes. The assembly is documented, among others, with a circuit diagram.
