Paper Abstract

This paper addresses the electromagnetic immunity of the embedded controller area network (CAN) controller in microcontroller to the conducted disturbances. The immunity of the CAN controller is measured with the direct RF power injection method. The results show that when electromagnetic interference(EMI) with its frequency ranged from 750MHz to 1000MHz is coupled from the ground network into the chip , compared with the power network, the immunity decreases by 2-4 dBm. In addition, the immunity of controller with transmission rate of 10 Kbps is 2.37 dBm lower than that of the controller with the transmission rate of 1 Mbps when the EMI with frequency of 660M is injected through the power network. The electromagnetic immunity of CAN controller is positively correlated with the signal transmission rate.
