CAN Controller

The CAN Controller IP Core is a high-performance, silicon-proven solution for Controller Area Network (CAN) communication, fully compliant with the ISO 11898-1 standard. Supporting both Classical CAN (2.0A/B) and CAN FD, the core is designed for seamless integration into FPGA, ASIC, and SoC platforms. Flexible APB and AXI interfaces enable easy connection to a variety of bus architectures, making it ideal for automotive, industrial, and embedded applications. The core features advanced error handling, robust message filtering, and programmable acceptance masks to ensure reliable and secure data transmission even in noisy or mission-critical environments. Integrated transmit and receive FIFOs, hardware prioritization, and automatic retransmission maximize bus efficiency and minimize latency. Comprehensive interrupt support and detailed status reporting streamline software development and system diagnostics.
