PCI1001-I/5CW

Specialized Overview

The PCI1001-I/5CW is a PCIe Gen4x16 fanout switch from the PCI100x family, designed for non-blocking connectivity with up to 256 GB/s switching capacity. It features one 4-lane upstream port and three 4-lane downstream ports, supporting full line rates of 16GT/s per lane. The device 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

• Supports Non-Transparent Bridge (NTB) functionality for Root Complex connections with configurable domains and address translation.
• Includes firmware security features such as Secure Boot from SPI flash and OEM-controlled Root of Trust for configuration signing.
• Provides comprehensive diagnostics via ChipLink tools, enabling real-time eye capture and TLP latency analysis over PCIe or sideband signals.

Specialized Applications

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

Specialized Procurement Notes

Verify the specific ordering suffix against the Product Identification System table to confirm the correct temperature grade and packaging format. The 'I' suffix indicates the industrial temperature range (-40°C to +85°C), while '/5CW' denotes the 353-ball FCCSP package and tray shipping method. Ensure compatibility with system power requirements and thermal design limits before finalizing procurement.

Specialized Selection Notes

Select this component when a low-lane count PCIe Gen4 switch is required for fanout applications without Non-Transparent Bridge capabilities. Compare against the PCI1005 variant if additional downstream ports are needed, or consider the PCI1003/PCI1004 models if NTB support is necessary for isolated domain access. Confirm that the 353-ball FCCSP package fits the PCB layout constraints.

Specialized Part Context

This part belongs to the SwitchtecTM Low Lane Count PCIe Gen4x16 Switch Family, which offers data center-grade performance in a compact form factor. The PCI1001 variant specifically provides a 4-port configuration optimized for connecting multiple endpoints to a single host root complex, serving as a bridge between high-bandwidth hosts and peripheral devices.
