CANmodule-III is a feature-rich CAN controller designed to optimize communications in embedded systems. It supports the concept of mailboxes, offering 16 receive buffers and 8 transmit buffers, each with its own filter for precise control. The module is compliant with the ISO 11898-1 standard for CAN 2.0A/B, making it suitable for automotive and industrial applications where robust and reliable communication is critical. With an AMBA 3 APB interface, it integrates smoothly into ARM-based SoCs, while its synchronous design allows for efficient operation without waiting periods.
This module's architecture includes a programmable priority arbitration mechanism, ensuring that messages with a higher priority are transmitted first, an essential feature in systems where timing is crucial. Its design is scalable, allowing for adaptation to specific system requirements, making it versatile for use in various embedded systems. The module also supports features like single-shot transmission and offers debugging support through listen-only and loopback modes.
In addition to its core functionality, the CANmodule-III boasts a robust interrupt management system, capable of handling multiple error sources. This includes a locally controlled interrupt and an optional external AHB interface for broader system compatibility. All these features are designed to ensure seamless integration into larger systems, providing a comprehensive CAN controller solution that is adaptable and efficient.
