Implement HSR/PRP with a Single Chip: SpeedChips XRS7000 Family

Flexibilis’ brand new product family is first of its kind in the world: An integrated circuit with which you can add HSR/PRP functionality to your device. This new chip series is called XRS7000 and is part of Arrow Electronics’ SpeedChips product family.

HSR and PRP are standardized redundancy protocols (IEC 62439-3 Clause 5 & 4) for wired Ethernet and provide zero-loss redundancy with no single point of failure. The aim of redundancy is to make fail-safe systems and HSR is currently the most efficient redundancy protocol available for Ethernet.

There are two different chips available which both have HSR and PRP support: XRS7003 (three ports) and XRS7004 (four ports). The chips also include IEEE 1588v2 Precision Time Protocol (PTP) transparent clock functionality. They can be used for example in industrial automation, motion control, substation automation, vehicle communication and networking equipment.
