Industrial CAN Sensor Network

In industrial applications, the Controller Area Network (CAN) is the most widely used device-level communication bus, with high reliability and cost performance. Sensors are also widely used in industrial applications to measure, for example, air quality and humidity. This design illustrates a sensor data collection network using the CAN functionality in the Renesas’ Arm^® core MCU platform, RA2L1 with an embedded M23 core. CAN transceivers are connected by an isolated RS-485 transceiver and an inverter. Additionally, different Renesas sensor modules work on CAN networks.

System Benefits​:

• Arm^® Cortex^®-M23 core, running on 48MHz for outstanding performance
• Encryption library integrated into the MCU for safety communication
• Robust communication interface implementing high-speed RS-485 transceiver
