CAN plays a very important role in Industry 4.0; compared to traditional RS485 and industrial Ethernet, CAN provides more favorable conditions for industrial applications.
• The transmission distance of CAN Bus and the number of devices that can be connected to it are far more than RS485
• CAN also has far better levels of data accuracy compared to RS485
• Compared to industrial Ethernet, the level of immediacy of CAN is relatively better than Ethernet
The main feature of Nuvoton NUC980 series microcontroller is the built-in high capacity DRAM 128 MB SDRAM because built-in DRAM can save on overall cost, reduce PCB size significantly and lower electromagnetic interference (EMI). They also have many peripheral functions including 10 sets of UART serial ports, 4 sets of CAN 2.0 B, 8 sets of USB Host and dual-Ethernet, able to provide the requirements for Industry 4.0 CAN gateway applications.
