Industrial Communication Protocols Supported on Sitara Processors and MCUs
Industrial communication is typically handled by the Programmable Real-Time Unit Industrial Communication Subsystem (PRU-ICSS) in Sitara processors and microcontrollers (MCUs). The PRU-ICSS is a co-processor subsystem containing Programmable Real-Time (PRU) cores and Ethernet media access controllers (EMACs), which implement the low level industrial Ethernet and fieldbus protocols through firmware.
