CAST Adds Switched TSN Endpoint Controller to Time-Sensitive Networking Ethernet IP Cores Family

Woodcliff Lake, NJ — January 17, 2020
Enables easy implementation of small, low-power, low-latency TSN Ethernet nodes for daisy-chained or ring networks

Semiconductor intellectual property (IP) provider CAST, Inc. today announced the availability of a new IP core implementing a switched endpoint controller supporting the Time-Sensitive Networking (TSN) Ethernet standards.

The new TSN-SE TSN Ethernet Switched Endpoint Controller IP core integrates hardware stacks for timing synchronization (IEEE 802.1AS), traffic shaping (IEEE 802.1Qav and IEEE 802.1Qbv), frame-preemption (IEEE 802.1Qbu and IEEE 802.1Qbr), and a low-latency Ethernet MAC.

The company believes the TSN-SE to be one of the smallest and most energy-efficient such cores available, and it features remarkably low latency, implementing nearly every function in hardware. Furthermore, the endpoint controller portion of the core has been proven in multiple industry plugfests, public demos, and customer applications.

“Industrial and automotive systems designers can now build efficient TSN Ethernet ring networks with all the technical features, reliability, performance, easy reusability, and great customer support CAST IP cores are known for,” said CAST CEO Nikos Zervas.

About the TSN-SE Switched Endpoint Controller Core

Sourced from partner Fraunhofer IPMS, the new core builds on the Fraunhofer/CAST team’s market-leading technical and customer experience helping customers integrate TSN Ethernet and other industrial and automotive interfaces.

The highly-competitive core enables high-precision timing synchronization and flexible yet accurate traffic scheduling. Cut-through switching and minimal buffering—even at the Ethernet MAC level—enable extremely low and deterministic input and output latencies. Standard AMBA® interfaces and other features facilitate easy system integration, simplifying the development of time-aware daisy-chained networks.

The TSN-SE is available now, in synthesizable Verilog source code or as a targeted netlist for Intel, Xilinx, or Lattice FPGA devices. It joins TSN Endpoint and CAN-to-TSN Gateway cores in CAST’s popular Automotive Interfaces family, which also includes IP for CAN 2.0/FD, LIN, and SENT.
