Sitara Processors – Grid infrastructure

TI's Arm™ and DSP processors cover all functions of grid infrastructure equipment:

Single Chip Drive to connect, control & communicate

Protection relays

Protection relays (also called intelligent electronic devices, IEDs) monitor and analyze process parameters and make quick decisions to protect grid equipment. Low-latency real-time communication is required for connecting to switchyard equipment, and reliable upstream communication is needed to transmit data to higher layers of SCADA control. Protection relays also must quickly process parameters such as IEC61850 sampled values (SV). TI's Sitara processors provide single chip, cost-optimized solutions for protection relays.

Benefits

  • Single chip solution for control, communication, and analytics.
  • Integration of HSR, PRP, and other protocols.
  • Scalable platform of Arm-Cortex devices enables re-use across wide range of equipment

Differentiators

  • Arm Cortex-A15 and Cortex-M4 cores, TI C66x DSP cores, and PRU-ICSS on a single chip for <4W.
  • HSR and PRP solutions for PRU-ICSS subsystems on AM335x, AM437x, and AM57x.
  • Wide range of peripherals including up to 6 ports of Ethernet from highest-end devices.

Industrial Ethernet switches

Industrial Ethernet switches in the power grid require high reliability, high security, and a large number of Ethernet connections. Increasing amounts of data need to be transported over the wide area network as more grid equipment becomes Ethernet-based. This creates a need for high performance, high-reliability Ethernet switches; TI's Sitara portfolio scales from entry-level to high-end solutions with common software and security solutions across the family.

Benefits

  • Large number of Ethernet ports and integrated HSR and PRP eliminate external switching or protocol components.
  • High performance with low power consumption enables fanless designs without compromising on features.
  • Cryptographic accelerators and optional secure boot provide security features without the use of external components.

Differentiators

  • HSR and PRP solutions and up to 6 ports of Ethernet for high number of reliable connections.
  • Sitara family scales from Cortex-A8 to dual Cortex-A15 with common software.
  • High reliability of up to 100K power on hours and industrial temperature ranges.

Merging units

Merging units take in process data from switchyard equipment over serial-based connections and send out the information over Ethernet networks for protection relays and other Ethernet-based relay room equipment. Merging units can contain a large number of signal processing cards in addition to a front end; the high number of processing units requires low power consumption to keep designs fanless.

Benefits

  • Software reusability across a broad portfolio of devices.
  • Fewer analog components due to high integration.
  • Industrial protocols implemented  through the PRU-ICSS

Differentiators

  • Industry-leading low power consumption plus wide temperature ranges suitable for rugged use cases.
  • Software support across the Sitara family for RT Linux, Linux, and TI-RTOS for real-time applications.

Renewable energy gateways 

Renewable energy gateways connect solar or wind inverters with users, utilities, and the cloud. Sitara Arm processors provide a wide range of peripherals to connect to both the energy side, such as a solar inverter, and to the rest of the world. AM335x is a simple solution for renewable energy gateways because it has a large industrial peripheral set and flexible, easy to use software including mainline Linux and commercial options. 

Benefits

  • Software reusability across a broad portfolio of devices. 
  • Fewer analog components due to high integration.
  • Industrial protocols implemented  through the PRU-ICSS.

Differentiators

  • Scalable portfolio of Arm Cortex processors from Cortex A8 and beyond.
  • Support for several peripherals like CAN, WI-FI, RS-232, and USB.
  • Support for several protocols including EtherCAT, HSR, PRP, and more.
