PCI Express System Interconnect Solutions

Renesas introduced the industry’s first PCI Express Gen1, Gen2 and Gen3 system interconnect solutions. Consisting of a broad family of configurations for control, data and services plane traffic, the solutions provide deterministic, non-blocking, line rate performance and advanced support for inter-processor communications and peripheral sharing in bladed and large-scale embedded applications. 

  • Delivers high performance and scalability
    • Industry’s first 64-lane devices offer 128GBps (Gen3), 64GBps (Gen2) and 32GBps (Gen1) capacity 
    • Industry’s first 16-port device increases system scalability
  • Enables flexible system scaling and optimal resource utilization
    • Multi-root support through partitionable switch architecture
    • Dynamic I/O allocation and sharing
    • Flexible I/O mapping
  • Ensures high RAS and security
    • Advanced multi-host failover
    • Endpoint security and isolation

PCI Express I/O Expansion Switching Solutions

The Renesas family of PCIe switches for I/O expansion is the broadest, most targeted set of solutions aimed at providing high-performance "aggregation" or "fan-out" switching to fill the connectivity gap created by north bridge devices with limited high-performance I/O expansion. The family offers the most comprehensive set of solutions with configurations ranging from 3 to 48 lanes and 3 to 12 ports.

  • Delivers high performance and scalability
    • Industry’s first Gen2 switches
    • Industry’s first 12-port switch
    • Cut-through switching architecture for low system latency
    • Support for a large number of flow control credits
    • 2 Kbyte maximum payload size (MPS)
  • Simplifies thermal management
    • Lower power, 20% to 50% lower than competitive offerings
    • Reduces or eliminates heat sinks, air flow requirements
  • Saves board space
    • Small footprint, up to 40% smaller than competitive offerings

PCI Express Inter-domain Switches

Inter-Domain Switches provide high-performance I/O connectivity and switching functions between a PCIe upstream port and one transparent and one non-transparent downstream ports.
