emotas CANopen FD stack supports DCD-SEMI standalone CAN FD controller
The list of supported targets for emotas’ CANopen FD stack has been expanded. The full-featured CANopen FD stack now supports the DCAN FD standalone CAN FD Controller from DCD-SEMI. Thus the CANopen FD stack can now also be used in FPGA systems with the DCAN FD IP core.
DCAN FD
The DCAN FD is a standalone controller for the Controller Area Network (CAN), widely used in automotive and industrial applications. It’s been designed in accordance to ISO 11898-1:2015 and conforms both to Bosch CAN 2.0B specification (2.0B Active) and CAN FD (flexible data-rate).
In automotive safety is the key issue, that’s why DCAN-FD emphasizes sophisticated error detection functions, which increase communication reliability and unique fault confinement, which guarantees network-wide data consistency.
Because of its fundamental role in all aspects of security and safety, trustworthy implementations are crucial. That’s why DCD-SEMI developed a unique IP Core, which delimits the highest quality standards. The improved protocol overcomes standard CAN limits: data can be transmitted faster than with 1 Mbit/s and the payload (data field) is up to 64 byte long and limited to 8 byte anymore. When only one node is transmitting, the bit-rate can be increased, because no nodes need to be synchronized. Of course, before the transmission of the ACK slot bit, the nodes need to be re-synchronized. The core has a simple CPU interface (8/16/32 bit configurable data width), with small or big endian addressing scheme. Hardware message filtering and 128 byte receive FIFO enable back-to-back message reception, with minimum CPU load. The DCAN FD is provided as HDL source code, allowing target use in FPGA and ASIC technologies.
