CAN Controller IP core
In the dynamic world of automotive electronics, reliable communication between electronic control units (ECUs) is essential, and the Controller Area Network (CAN) Bus has long served as the backbone of in-vehicle networking. With growing demands for higher bandwidth, faster data throughput, and stronger security, newer standards have evolved beyond Classical CAN.
Arasan’s CAN IP Controller Core supports the full range of standards—CAN XL, CAN FD, CAN FD Light, CAN 2.0, and CAN-SEC—delivering data rates up to 20 Mbps, larger payload capacities, and enhanced efficiency. These capabilities make it an ideal solution for high-resolution sensor data processing in advanced driver-assistance systems (ADAS) and autonomous vehicles.
