Overview

CAN FD Bus Controller IP is an extension of Classical CAN Bus IP that addresses the increasing need for higher data rates and larger payload sizes. It enhances the original CAN protocol by enabling faster communication and increased bandwidth. CAN FD Bus IP is particularly useful in applications such as advanced driver-assistance systems (ADAS), infotainment systems, and diagnostic tools, where high-resolution sensor data, multimedia content, and firmware updates require higher data throughput.

The Controller Area Network – Flexible Data (CAN-FD) Controller IP implements the CAN 2.0A, CAN 2.0B as well as the high-performance CAN-FD (Flexible Data Rate) protocols. It is compliant to both Non-ISO CAN-FD from BOSCH as well as ISO11898-1:2015 DIS. It can be integrated into devices that require CAN connectivity commonly used in automotive and industrial applications.

Arasan’s CAN-FD Controller core is easy to integrate with the Host processor using AMBA-AXI standard interface. This highly configurable design supports programmable Interrupts, data and baud rates, acceptance filters & buffering schemes specific to the application.
