CAN FD Bus Controller

Overview

The Controller Area Network (CAN) controller IP that implements the CAN2.0A, CAN2.0B as well as newer high performance Non ISO CAN-FD protocols. It can be integrated into devices that require CAN connectivity commonly used in automotive and industrial applications.

Key Features

ASIL-C, ISO26262 Certified, Automotive Grade
Implements the CAN 2.0A and CAN 2.0B protocols
Supports ISO CAN-FD-ISO 11898-1:2015 DIS protocols
Non-ISO BOSCH CAN-FD Protocol
64 data bytes to multiple megabytes
Time-stamping support, compliant to CiA0603 specification
TTCAN (ISO 11898-4 level-1)
Optimized for AUTOSAR and SAE J1939
ISO26262 Certified, CAN2/0/CAN-FD Compliant, and designed for ASIL-B
Advanced Features
SDB-Software Defined Buffers, to support large external and small internal memories with minimum latency
Optimized design for short data frames to create latency advantage(best for CAN-FD)
Highly configurable design for data rate, baud-rate, interrupt sources and mix-bit options
Low software overhead, future-proof design
RAS Features
Advanced Error management unit prevents data loss during transmission and prevents message collisions
Designed to increase reliability, faster error reporting
Separate CRCs for CAN2.0 and CAN-FD
Frame or Format error reporting is done on the receiver side in a timely manner
Supports debug, system maintenance and system optimization for Last error types, Arbitration lost position, error threshold indicators and others
Special listen-only mode for CAN/CAN-FD traffic analysis and automatic bit-rate detection for performance measurement
Loopback mode for debug and self-testing during integration and system bring-up
