Arasan’s Controller Area Network – Flexible Data-Light (CAN-FD Light) Controller IP implements the CAN FD-Light (CIA 604-1) protocol. It can be integrated into devices that require CAN-FD-Light connectivity commonly used in sensors and actuators for the automotive and industrial applications.
Arasan’s CAN-FD-Light Controller core is easy to integrate with the Host processor using AMBA-APB standard interface. This highly configurable design supports programmable Interrupts, data and baud rates, acceptance filters & buffering schemes specific to the application.
Choosing the Right CAN Bus Standard for Specific Applications
The choice of a specific CAN bus standard depends on the application requirements, including data rate, payload size, cost, and criticality. Here are some key considerations for selecting the right standard:
1. Bandwidth and Data Throughput: Applications requiring high-speed data transfer and large payload sizes, such as ADAS, infotainment systems, and autonomous vehicles, would benefit from CAN FD Bus Controller IP and CAN XL Controller IP due to their higher data rates and enhanced bandwidth.
2. Real-Time Requirements: Safety-critical applications that demand deterministic and real-time communication, like powertrain control and chassis control, can rely on Classical CAN IP core due to its proven reliability and fault confinement mechanisms.
3. Cost Considerations: It provides a balance between functionality and affordability.
4. Compatibility and Legacy Systems: When existing systems or networks are already based on Classical CAN, backward compatibility becomes crucial. Upgrading to CAN FD IP or CAN XL IP may require additional infrastructure changes, while maintaining Classical CAN compatibility can be a more straightforward transition.
5. Future Scalability: For applications where future scalability and compatibility with emerging technologies are critical, such as advanced telematics systems, CAN XL Bus IP provides an ideal choice. Its extended capabilities and larger payload sizes offer room for future growth and evolving communication requirements.
