CAN-XL Bus Controller IP

Overview

The CAN-XL Bus Controller Core performs serial communication as per CAN 2.0, CAN-FD & CAN-XL Specifications. It also supports original Bosch Protocol & ISO 11898 specifications for TTCAN (Time Triggered Operation) as specified in ISO11898-4. The design is fully optimized to support AUTOSAR and SAE J1939 specifications. The CAN-XL 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.
