CAN-FD Controller IP

OverviewFeaturesRequest Datasheet
The DCAN FD is a standalone controller for the Controller Area Network (CAN), widely used in automotive and industrial applications. It conforms to Bosch CAN 2.0B specification (2.0B Active) and CAN FD (flexible data-rate). The improved proto- col overcomes standard CAN limits: data can be transmitted faster than with 1 Mbit/s and the pay- load (data field) is up to 64 byte long and limited to 8 byte anymore. When only one node is transmit- ting, 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 recep- tion, with minimum CPU load. The DCAN FD is provided as HDL source code, allowing target use  in FPGA or ASIC technologies.
