PCI1005-I/5CW

Specialized Overview

The PCI1005-I/5CW is a PCIe Gen4x16 fanout switch manufactured by Microchip Technology. It features seven ports: one upstream port configured as x4 and six downstream ports configured as x2, providing a total of 16 lanes. The device supports a switching capacity of up to 256 GB/s with full line rate performance at 16GT/s per lane. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 353-ball FCCSP package measuring 16 x 16 mm.

Specialized Feature Summary

• Non-blocking architecture supporting bifurcation to x2/x4 lanes and enumeration of x1 devices on any port
• Integrated firmware security including OEM-controlled Root of Trust for Secure Boot from SPI flash
• Comprehensive diagnostic capabilities via ChipLink tools for signal integrity analysis and error monitoring
• Supports Active State Power Management (ASPM) with L0, L1, L2, and L3 link states

Specialized Applications

• Level 2/3 Advanced Driver-Assistance Systems (ADAS)
• Defense & Aerospace Compute Applications
• Embedded Servers & Industrial PCs
• Video Acceleration Equipment

Specialized Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature rating. The '-I' suffix indicates the industrial temperature range (-40°C to +85°C), while '/5CW' denotes the 353-ball FCCSP package. Confirm whether the required quantity necessitates Tray or Tape & Reel packaging options available for this family.

Specialized Selection Notes

Select the PCI1005 variant when a non-Transparent Bridge (NTB) configuration is not required, as this model provides zero NTBs compared to other family members. Ensure the system design accommodates the specific port lane distribution of one x4 upstream port and six x2 downstream ports for optimal bandwidth utilization.

Specialized Part Context

This component belongs to the PCI100x family of low-lane count PCIe Gen4 switches. Unlike the PCI1003 or PCI1004 models which include Non-Transparent Bridge capabilities, the PCI1005 is designed specifically as a fanout switch without NTB support. It shares the same 353-ball FCCSP package and core switching technology as its siblings.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult Microchip technical support for cross-reference information regarding alternative components.
