Microchip PCI12000-I/ZUX, Ethernet Switch IC SPI, SPI, 72-Pin VQFN

The Microchip single-chip 3-port PCIe switch with an integrated programmable I/O. The integrated PCIe physical interfaces provide a 2-lane (2x8GT/s) upstream port and two 1-lane (1x8GT/s) downstream ports. The device is targeted to address the need for higher bandwidth PCIe sub-systems within embedded applications. PCIe upstream can be delivered across a single or multiple lanes to accommodate best system architecture. The PCI12000 includes a compliant PCIe implementation from external facing physical interfaces through to switch fabric and endpoint controllers.
