SpeedChips XRS7000 Series

Single chip HSR & PRP switch

XRS7000 series switches are integrated circuits (ICs) with which you can add HSR, PRP and time synchronization functionality to your device. This chip series is the first off-the-shelf HSR/PRP Ethernet chip in the market and is part of Arrow Electronics’ SpeedChips product family.

XRS7000 series switches offer availability and reliability for Ethernet networks and can be used for example in industrial automation, motion control, substation automation, vehicle communication and networking equipment. HSR and PRP are standardized redundancy protocols for Ethernet providing zero-loss redundancy with no single point of failure.

Features: XRS7003 & XRS7004

There are two different XRS7000 versions available: XRS7003 (three ports) and XRS7004 (four ports). XRS7003 can be employed in HSR and PRP end nodes and XRS7004 in both end nodes and HSR and PRP RedBoxes. A QuadBox can be built using two XRS7004 devices.

  • Compatible with High-availability Seamless Redundancy (HSR)
  • Compatible with Parallel Redundancy Protocol (PRP)
  • Two (XRS7003) or three (XRS7004) 10/100/1000 Mbit/s RGMII ports
  • Time and frequency synchronization using IEEE1588-2008 Precision Time Protocol v2
  • I2C and MDIO for register access
  • Cut-through and store-and-forward operation
  • Quality of Services (QoS) with priority tagging, packet filtering and four priority queues per port
  • Port-based VLAN and VLAN tagging
  • PPS (Pulse per Second) input and output
  • Support for MAC address based authenticating methods
  • RMON statistics counters
  • Two industrial range packages available: 144-Pin Plastic Enhanced Quad Flat Pack (EQFP) and 256-Pin Fine Line Ball Grid Array (FBGA)
