DCAN - Configurable CAN Bus Controller

DCAN - Configurable CAN Bus Controller Description:

Overview

The DCAN is a stand-alone controller for the Controller Area Network (CAN) widely used in automotive and industrial applications. DCAN conforms to Bosch CAN 2.0B specification (2.0B Active). Core has simple CPU interface (8/16/32 bit configurable data width) with little or big endian adressing scheme. Hardware message filtering and 64 byte receive FIFO enables back-to-back message reception with minimum CPU load. The DCAN is described at RTL level allowing target use in FPGA or ASIC technologies.
