PCI1001/3/4/5 Switchtec™ PCIe Switches

Microchip Technology PCI1001/3/4/5 Switchtec™ Low Lane Count PCIe Switches build on the legacy of Microchip’s high‑performance Switchtec product line. These devices deliver many of the features found in larger data‑center‑class switches, but in a compact, low‑lane‑count format that supports flexible PCIe connectivity and efficient system design. A smaller form factor makes the components ideal for System-on-Chip (SoC) and accelerator interfaces, as well as for expanding port‑ or lane‑limited PCIe connections. The PCIe Gen 4 switch family complies with the PCIe Base Specification 4.0 and supports up to 16 lanes, offering Non‑Transparent Bridge (NTB) options, embedded low‑power states, and extensive diagnostics and debugging capabilities.
