Sitara processors – Industrial communication

TI's Sitara Arm® processors feature a unique peripheral, the Programmable-Real time Unit Industrial Communications Subsystem (PRU-ICSS), which eliminates the need for an external ASIC or FPGA by enabling the integration of real-time industrial Ethernet and Fieldbus protocols.

Ethernet, Fieldbus, encoder and redundancy protocols are available for the PRU-ICSS, including certified solutions for EtherCAT, Profibus, Profinet and others. The PRU-ICSS supports multiple protocols on the same hardware using firmware supplied by TI through the industrial software packages and stacks from industry partners.

PRU-ICSS (Programmable Real-Time Unit Industrial Communication Subsystem) is a subsystem containing Programmable Real-Time (PRU) cores which run Ethernet and Fieldbus protocols. PRU cores are mainly used for industrial communication, but can also be used for general purpose applications.

• Support for multiple protocols on one platform:
  • PROFIBUS, PROFINET (RT/IRT), SERCOS-III, Ethernet/IP (with DLR), POWERLINK, EtherCAT, CC-Link IE Field Basic and others
  • Master and Slave protocols
  • Redundancy protocols such as HSR & PRP
  • Encoder protocols such as BiSS C, EnDAT 2.2, Tamagawa and HIPERFACE DSL
  • Standard 10/100Mb Ethernet
• Fully tested, certified, and supported solutions
• Protocol-specific software available from TI’s industrial software package
• General-purpose software available from Processor SDK
