CAN Controller interface provides full support for the two-wire CAN Controller synchronous serial interface, compatible with CAN 2.0 A/B ISO 11898 and CAN FD 1.1 specification. It supports the original Bosch protocol and ISO specifications as defined in ISO 1989, including time-triggered operation (TTCAN) as specified in ISO 19898-4 and is also optimized to support the popular AUTOSAR and SAE J1939 specifications. The core implements functionality similar to the Philips SJA1000 working with its PeliCAN mode extensions, providing error analysis, diagnosis, system maintenance, and optimization features. Through its CAN Controller compatibility, it provides a simple interface to a wide range of low-cost devices. CAN Controller IIP is proven in FPGA environment.The host interface of the CAN Controller can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
