CAN Controller IP

Design IP

Overview

SmartDV’s CAN (Controller Area Network) Controller IP is a silicon-proven solution designed for reliable, real-time communication across automotive, industrial, and embedded systems. Fully compliant with ISO 11898 standards, the IP supports Classical CAN, CAN FD, and optionally CAN XL, enabling a scalable path from legacy networks to next-generation high-bandwidth automotive architectures.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance.

SmartDV also offers ASIL-ready variants to meet ISO 26262 functional safety requirements, making this IP ideal for safety-critical automotive applications. With support for features such as advanced error handling, time-triggered transmission, message filtering, and flexible buffering, the CAN Controller IP ensures dependable communication across even the most demanding networks.

Benefits

Flexible Protocol Support – Compliant with CAN 2.0 A/B (ISO 11898), CAN FD 1.1, and CAN FD Light 1.0.1 for broad protocol coverage in automotive and industrial applications
High Reliability for Safety-Critical Systems – Supports full CAN transmit/receive functionality, all frame types (data, remote, error, overload), automatic remote frame response, and extensive error detection (bit, stuff, CRC, form, and ACK errors)
Optimized for Real-Time Performance – Enables bit rates up to 1 Mbps (Classical CAN) and 5 Mbps (CAN FD), with support for single-shot transmission, self-reception, and programmable interrupt generation for precise error and arbitration handling
Customizable Bit Timing – Offers configurable bit timing parameters and programmable clock output to support diverse network timing and topology requirements
Scalable Message Buffering – Provides support for TEC/REC error count registers (read/write), message filtering via single and double filters, and optimized buffering for SAE J1939 and AUTOSAR applications
